Answer: m = 2
Step-by-step explanation:
What we know:
The slope needs to pass through the points (1, -5) and (4, 1)There are 4 potential slopes given to us- only one is correctWe need to find the slope and make sure it is an optionHow to solve:
By using the slope equation and the two points given to us, we can calculate the slope.
Process:
Set up equation (y2 - y1) / (x2 - x1)Substitute (1 +5 ) / (4 - 1)Simplify 6 / 3Simplest form 2/ 1 =Slope = 2
Solution: m = 2

equation of the line (6,10) , (-3,-2)
Answer:
[tex]y=\frac{4}{3}x+2[/tex]
Step-by-step explanation:
using two points you can find the slope of the line using the formula [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
plugging in the x- and y- values into the equation above, you'll get:
[tex]m=\frac{-2-10}{-3-6}=\frac{-12}{-9}=\frac{4}{3}[/tex]
so far, you have [tex]y = \frac{4}{3}x+b[/tex]
using any of the two points, you can solve for b. in this case, the point (-3, -2) is used.
[tex]-2=\frac{4}{3}(-3)+b\\-2=-4+b\\-2+4=-4+b+4\\2=b[/tex]
the overall equation is [tex]y=\frac{4}{3}x+2[/tex]

−1.3=x−(−13.2)
What is the solution to the equation?
Enter your answer in the box.
x =
x= -14.5
Step-by-step explanation:
-1.3=x-(-13.2)
the two - signs cross eachother out, making it a +.
making the equation -1.3=x-(-13.2) turn into -1.3=x+13.2.
so you should automatically know your x is going to have to be negative.
What I did:
13.2+1.3=14.5,
but since the 1.3 was actually negative, (-1.3) the 14.5 will turn negative, making it -14.5
3. Allison bought some shirts for her clothing store for $15 each. She received $50 off her entire purchase and spent a total of $400. How many shirts did Allison purchase for her store?
Answer:
30
Step-by-step explanation:
15x30 = 450
Answer:
She purchased 30 shirts.
Step-by-step explanation:
She paid only $400 Dollars, because she got a discount of $50.
So the total before getting the discount was $450.
If you divide $450 by $15 (the price for 1 shirt) you come up with 30.
450/15 = 30

Answer:
-7.5x -12.5, x < -17.5x +2.5, x ≥ -1Step-by-step explanation:
The absolute value function changes slope at its vertex. Here, that vertex is translated to x = -1. To the left of that point, the function is equivalent to one that negates its argument:
|x| = -x . . . for x < 0
|x| = x . . . for x ≥ 0
for (x+1) < 0
y = -7.5(x +1) -5 = -7.5x -12.5
for (x+1) ≥ 0
y = 7.5(x +1) -5 = 7.5x +2.5
This means we can write the piecewise function as ...
[tex]y=\begin{cases}-7.5x-12.5,&\text{if }x<-1\\7.5x+2.5,&\text{if }x\ge-1\end{cases}[/tex]
Juan has 20 books to sell. He sells the books for $15 each.
The amount of money Juan makes from selling x books is represented by the equation y=15x
y
=
15
x
What is the theoretical range of the equation?
Question 2 options:
All multiples of 20 between 0 and 300, inclusive
All integers from 0 to 20, inclusive
All multiples of 15 between 0 and 300, inclusive
All real numbers
Answer:
Well u would multiply 20 x 15 to find out the highest if the range which is 300 . So that knocks it down to B or D. But since they're $15 each, It would be based of the multiples of 15 making your answer B .
The range is all the y values.....or the f(x) values .
So the practical range would be the multiples of 15 between 0 and 300,Inclusive .

A class of 30 students visits an art museum and a special exhibit while there.
a. Use the Distributive Property to write and simplify an expression for the cost.
b. Estimate a reasonable value for x. Explain.
c. Use your estimate for x to evaluate both expressions in part (a). Are the values the same?
PRICES:
Museum Exhibit
Child (under 5) Free Free
Student $8 $x
Regular $12 $4
Senior $10 $3
Answer quick!!
A reasonable price for X would be $ 2.
Since a class of 30 students visits an art museum and a special exhibit while there, and the prices were as follows:
Child (under 5) Free Free Student $ 8 $ x Regular $ 12 $ 4 Senior $ 10 $ 3
To estimate a reasonable value for x, the following logical reasoning must be made:
Regular 12 Senior 10 Student 8 = -2 Regular 4 Senior 3 = -1
Therefore, a reasonable price for X would be $ 2.

There are 4 Year 11 pupils in a football club, out of a total of 29 pupils.
Write this proportion as a percentage.
Give your answer correct to 1 decimal place when appropriate.
Answer:
14%
Step-by-step explanation:
So if we have 4 Year 11 pupils out of a total of 29 pupils at a football club, the fraction for that would be 4/29, if we convert 4/29 into a decimal number we get 0.13793103448, so we round this number up to the nearest 1 decimal place, and that would be 0.14 which equals 14%. Hope this helps.

Mae buys 7 boxes of drinks. The cost of each box of drinks is £7 and each box holds 12 cans.She sells 3/4 of the total number of cans for 70p each and the remaining cans for 40p each. WORK OUT THE TOTAL OF PROFIT HE MAKES
Answer:
£3.50
Step-by-step explanation:
The total number of cans Mae bought was ...
(12 cans/box)×(7 boxes) = 84 cans
The revenue from sales is ...
(3/4)(84)(70p) +(1/4)(84)(40p) = 84(3/4×70p +1/4×40p) = 84(52.5p +10p)
= £52.50
The cost of the drinks was ...
(£7/box)×(7 boxes) = £49.00
Mae's profit is the difference between her sales revenue and her cost:
profit = revenue - cost
profit = £52.50 -49.00 = £3.50

Determine whether the ratios form a proportion.
16/9, 28/15
Answer:
No
Step-by-step explanation:
One way of doing this problem is to reduce the given fractions as much as possible. Unfortunately, neither ratio reduces. So the fraction 16/9 is NOT equal to the fraction 28/15 and our conclusion must therefore be "the rations do not form a proportion."
