Solve the inequality. Graph the solution.
−8 ≤ z + 6.4
Answers
Answer:
Solve for z- by simplifying both sides of the inequality, then isolating the variable.
Inequality Form:
z≥−14.4
Step-by-step explanation:
The solution of the inequality −8 ≤ z + 6.4 is z ≥ 14.4.
What are open and closed circles?A closed circle on a point represents including(less than or equal to or greater than or equal to) the point and an open circle on a point represents we are not including(strictly less than or greater than) that point.
The solution of the inequality −8 ≤ z + 6.4 is,
z ≥ 6.4 + 8.
z ≥ 14.4.
∴ The graph of the inequality z ≥ 14.4 will be a line denoted by a closed circle at 14.4 to infinity or a region greater than or equal to 14.4.

the number 1953125 is equal to 5^9
explain how the infomation above informs that 1953125 is not a square number
Answers
Step-by-step explanation:
Given
[tex]1953125=5^9[/tex]
For a perfect square, its square root must be an integer
The square root of 1953125 i.e. [tex]\sqrt{1953125}=\sqrt{5^9}[/tex]
or, [tex]\sqrt{5^9}=5^\frac{9}{2}[/tex]
Clearly, [tex]\frac{9}{2}[/tex] is not an integer so, [tex]5^{\frac{9}{2}}[/tex] is also not an integer
Hence, 1953125 is not a square number

Abi and Ali shared £35 in the ratio 1 : 6.
Work out how much Ali received.
Answers
Answer:
£30
Step-by-step explanation:
To tackle these 'sharing' ratios problems, first find the total amount parts in the ratio.
1 : 6 = 1 + 6 = 7 parts
Now divide the total amount of parts by the total amount of money shared
35 / 7 = 5
Now multiply the answer by the value that is appropriate.
In this case, they want you to work out how much Ali recieved.
Ali's value is 6
6 × 5 = £30
hope this helps :)
If Abi and Ali shared £35 in a ratio of 1: of 6, Ali received £210.
What is the ratio?
It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
It is given that, Abi and Ali shared £35 in a ratio of 1: of 6.
We have to apply operations in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
Suppose the share of Abi and Ali is 1x and 6x and the total amount they shared is £35.As a result,
x+6x=£35
7x=£35
x=£5
The amount Ali received is found as,
=6x
= 6×£35
=£210
Thus, if Abi and Ali shared £35 in a ratio of 1: of 6, Ali received £210.

Function 2
y = 5x + 4
How much more is the rate of change of function 2 than the rate of change of
function 1? (4 points)
Answers
Primarily, horizontal lines mean zero slope. Therefore the equation is y= 3 because you are only left with the y-intercept at this point. The rate of change is another way of saying slope. Function 2's slope is 5 and function 1's slope is 0. Therefore, the rate of change of function 2 is greater than the rate of change of function 1 by 5.
5 is the answer.

A local food truck specializes in gourmet grilled cheese sandwiches. Each month, the owners of the truck have a constant total of $7,900 in expenses (salaries, truck loan, etc.) and it costs $1.70 per sandwich to make each sandwich. The food truck sells its sandwiches for $7.75 each.
a) Write an inequality to represent how many sandwiches, s, the food truck will have to sell each month to earn more money from selling sandwiches than it pays in expenses and sandwich costs.
b) Solve the inequality. Show your steps or explain your answer.
c) To gain more sales, the food truck offers a discount one month of $1.50 off its sandwiches.
How many more sandwiches will it need to sell to earn more money from selling sandwiches than it pays in expenses and food costs? Explain your answer, mathematically or in words.
Answers
Answer:
a) s × ($7.70 - $1.70) > $7,900
b) s > 1,306 sandwiches
c) 431 more sandwiches
Step-by-step explanation:
The question is
The given parameters are;
The constant total expenses (fixed cost), C = $7,900
The cost it takes to make each sandwich, [tex]p_s[/tex] = $1.70
The price at which the food truck sells its sandwiches, [tex]c_s[/tex] = $7.75
Where "s" represent the number of sandwiches sold, we have;
a) Therefore, the inequality that represent the number of sandwiches the food truck will have to sell each month to earn more money from selling sandwiches than it pays in expenses and sandwich costs is given as follows;
s × ([tex]c_s[/tex] - [tex]p_s[/tex]) > C
Substituting the known values, gives;
s × ($7.75 - $1.70) > $7,900.00
b) From the inequality, which we have;
s > $7,900/($7.75 - $1.70)
However, $7,900/($7.75 - $1.70) = 158,000/121 ≈ 1,305.79
We round up to the nearest whole number since we are counting sandwiches which are counted per each piece
Therefore;
s > 1,306 sandwiches
An explanation is that the food truck will have to sell more than 1,305 sandwiches to be earn more money than it pays in expenses and sandwich costs.
c) The amount in discount the food truck offers in a specific month = $1.50
Therefore, the amount the food truck sells the sandwich in the given month [tex]c_s[/tex] = $7.75 - $1.50 = $6.25
Therefore the number of sandwich the food truck company will have to sell on that month to earn more money from selling sandwiches than it pays the in expenses and sandwich cost, "s" is given as follows;
s × ([tex]c_s[/tex] - [tex]p_s[/tex]) > C
s × ($6.25 - $1.70) > $7,900, which gives;
s > $7,900/($6.25 - $1.70)
$7,900/($6.25 - $1.70) ≈ 1,73.26
We round up to get, s > 1,737
We round up
Therefore, the number of more (extra) sandwiches the food truck have to sell to earn money from selling sandwiches than it pays in expenses and food costs is the difference in the number of sandwiches it has to sell at $7.75 and $6.25 to earn more money than it pays in fixed expenses (costs) and the sandwich cost which is given as follows;
At $7.75 the number of sandwiches the food truck has to sell s > 1,306
At $1.70 the number of sandwiches the food truck has to sell is s > 1,737
The more number of sandwiches it has to sell = 1,737 - 1,306 = 431 more sandwiches
The more number of sandwiches it has to sell = 431 more sandwiches
(From which we check to have; 1306 + 431 = 1737 which is correct)
The inequality represents how many sandwiches, the food truck is [tex]s \times ($7.75 - $1.70) > $7,900.00[/tex]
The solution of the inequality is,1,305.79
The more number of sandwiches it has to sell is 1373 more sandwiches
Given that,
A local food truck specializes in gourmet grilled cheese sandwiches.
Each month, the owners of the truck have a constant total of $7,900 in expenses (salaries, truck loan, etc.) and it costs $1.70 per sandwich to make each sandwich.
The food truck sells its sandwiches for $7.75 each.
We have to determine,
Write an inequality to represent how many sandwiches, the food truck.
Solve the inequality.
To gain more sales, the food truck offers a discount one month of $1.50 off its sandwiches.
How many more sandwiches will it need to sell to earn more money from selling sandwiches than it pays in expenses and food costs
According to the question,
The constant total expenses (fixed cost), C = $7,900
The cost takes to make each sandwich, = $1.70
The price at which the food truck sells its sandwiches, = $7.75
Where "s" represents the number of sandwiches sold.
The inequality that represents the number of sandwiches the food truck will have to sell each month to earn more money from selling sandwiches than it pays in expenses and sandwich costs is given as follows;[tex]s \times (c_s-p_s)>c[/tex]
Substituting the known value in the equation,
[tex]s \times ($7.75 - $1.70) > $7,900.00[/tex]
The inequality, which we have; s > $7,900/($7.75 - $1.70)$7,900/($7.75 - $1.70)
= 158,000/121
≈ 1,305.79
The nearest whole number since we are counting sandwiches which are counted per piece.
Therefore;
s > 1,306 sandwiches
An explanation is that the food truck will have to sell more than 1,305 sandwiches to earn more money than it pays in expenses and sandwich costs.
The amount in discount the food truck offers in a specific month = $1.50 Therefore, the amount the food truck sells the sandwich in the given month = $7.75 - $1.50 = $6.25The number of sandwiches the food truck company will have to sell on that month to earn more money from selling sandwiches than it pays the in expenses and sandwich cost, "s" is given as follows;
[tex]s \times (c_s-p_s)>c[/tex]
s × ($6.25 - $1.70) > $7,900, which gives;
s > $7,900/($6.25 - $1.70)
$7,900/($6.25 - $1.70) ≈ 1,73.26
s > 1,737
Therefore, the number of more (extra) sandwiches the food truck have to sell to earn money from selling sandwiches than it pays in expenses and food costs is the difference in the number of sandwiches it has to sell at $7.75 and $6.25 to earn more money than it pays in fixed expenses (costs) and the sandwich cost which is given as follows;
At $7.75 the number of sandwiches the food truck has to sell s > 1,306
At $1.70 the number of sandwiches the food truck has to sell is s > 1,737
The more number of sandwiches it has to sell = 1,737 - 1,306 = 431 more sandwiches
The more number of sandwiches it has to sell = 431 more sandwiches
= 1306 + 431 = 1737

Elerick made 20 baskets during a basketball game. The number of 3-point shots was two more than half the number of 2-point shots. How many of each type of shot did he make? How many total points did he get?
Answers
Answer:
12 2-point shots and 8 3-point shots48 points in generalStep-by-step explanation:
The number of 3-point shots made is two more than half of the number of 2-point shots made.
Assume the number of 2-point shots is x.
Number of 3-point = 0.5x + 2
The relevant expression will be:
x + (0.5x + 2) = 20
1.5x + 2 = 20
1.5x = 20 - 2
x = 18/1.5
x = 12 shots
3 point shots = 20 - 12 = 8
There were 12 2-point shots and 8 3-point shots.
Total points :
= (12 * 2) + (8 * 3)
= 48 points
2.) Solve:
-24 - 2m = -4m - 8(m + 8)
Answers
Answer:
m = -4
Step-by-step explanation:
First, you should distribute -8 into m + 8 to get -8m - 64. Then, you should combine -4m and -8m together to get -12m as a result. Your equation should now be -24 - 2m = -12m - 64. Add 12 on both sides to get -24 + 10m = -64. Add 24 on both sides to get -40 on the right side. Finally, divide 10 on both sides to get your m value which is -4.
Answer:
-4
Step-by-step explanation:
-24 - 2m = -4m - 8(m + 8) (Remove the parentheses)
-24 - 2m = -4m - 8m - 64 (Collect like terms)
-24 - 2m = -12m - 64 (Move the term)
-2m + 12m = -64 + 24 (Collect like terms, Calculate)
10m = -40 (Divide both sides)
m = -4
