Answer:
(8, 0 )
Step-by-step explanation:
Given the 2 equations
y = 8 - x → (1)
y = 5x - 40 → (2)
Substitute y = 5x - 40 into (1)
5x - 40 = 8 - x ( add x to both sides )
6x - 40 = 8 ( add 8 to both sides )
6x = 48 ( divide both sides by 6 )
x = 8
Substitute x = 8 into either of the 2 equations and solve for y
Substituting into (1)
y = 8 - 8 = 0
Solution is (8, 0 )

Answer:
y=3/5,6
Step-by-step explanation:
Split the second term in 5{y}^{2}-33y+185y2−33y+18 into two terms.
5{y}^{2}-3y-30y+18=05y2−3y−30y+18=0
2
Factor out common terms in the first two terms, then in the last two terms.
y(5y-3)-6(5y-3)=0y(5y−3)−6(5y−3)=0
3
Factor out the common term 5y-35y−3.
(5y-3)(y-6)=0(5y−3)(y−6)=0
4

Solve for yy.
y=\frac{3}{5},6y=53,6
Answer:

The point that satisfies both the inequalities is (0, 3).
Correct option is (C).
What is Inequality?Inequalities are mathematical formulas in which neither side is equal.
As per the given data:
We are given two inequalities, and we have to find out whether the points that are given in the options are satisfying the solution set of the given inequalities or not.
The inequalities are as follows:
x + y > 2
4x + y ≥ -1
For option (A). (2, 0)
Substituting the points in the given inequalities.
2 > 2 and 8 ≥ -1
Hence, this is incorrect.
For option (B). (0, 2)
Substituting the points in the given inequalities.
2 > 2 and 2 ≥ -1
Hence, this is incorrect.
For option (C). (0, 3)
Substituting the points in the given inequalities.
3 > 2 and 3 ≥ -1
Hence, this is correct.
For option (D). (0, -1)
Substituting the points in the given inequalities.
-1 > 2 and -1 ≥ -1

Find the distance between -7, -3 2/3 on a number line.
Answer:
3 and 1/3 because 7 minus 3 and 1/3 equals 3 2/3 or you could also do 3+3=6 and 2/3+1/3=1 and 1+6=7
The distance between -7 and -3 2/3 on the number line is 3 1/3
How to determine the distance between the numbers?The numbers are given as:
-7 and -3 2/3
Calculate the absolute difference between both numbers
d = |-7 + 3 2/3|
Evaluate the difference
d = | 3 1/3|
Evaluate the absolute value expression
d = 3 1/3
Hence, the distance between -7 and -3 2/3 on the number line is 3 1/3

Mario had 12 apples and gave away x apples. Luigi had 26 apples and gave away three times as many apples as Mario did. How many apples did Mario give away if they had the same number of apples left?
Answer:
7 Apples
Step-by-step explanation:
For this question, we can write expressions for Maria's apples and Luigi's apples and form an equation as they end up with the same amount.
Mario starts with 12 apples but gives away x number. This means Mario's final amount of apples can be represented as: 12-x
Similarly Luigi starts with 26 and gives away 3 times the amount of Mario. So the number he gave away can be represented as: 3x (3 times the number Mario gave away). Therefore we can represent Luigi's final number as: 26-3x
Since they both end up with the same number of apples, we can put these expressions equal to each other in an equation to solve for x (the number of apples Mario gave away):
Mario Luigi
12-x = 26-3x
12-x=26-3x
Now we just need to move the unknowns to one side and the other terms to the other, combine and solve:
12-x-12=26-12-3x
-x=14-3x
-x+3x=14-3x+3x
2x=14
2x/2=14/2
x=7
Mario gave away 7 apples.
Hope this helped!
So I'm practicing writing Standard and Slope Intercept equations. Can anyone help me on writing both equations if the points are (3,5) and (0,0)?
Answer:
standard: 5x-3y=5
slope intercept: y=5/3x-5/3
Step-by-step explanation:
so standard form is: ax+by=c
(a must be positive)
slope intercept form is: y=mx+b
(m is the slope of the line that the two points form)
first, find the slope:
(y1-y2)/(x1-x2)
(5-0)/(3-0)
slope=5/3=m
to do slope intercept, b is the y-intercept
to find that plug in one of your pairs of numbers like so,
y=mx+b
0=5/3x+b
b=-5/3
now we have slope intercept form!!
y=5/3x-5/3
to do standard form:
first, take your slope intercept form; y=5/3x-5/3
then subtract 5/3x from both sides making:
-5/3x+y=-5/3
multiply everything by -3 to get rid of the fraction and the negative like so:
5x-3y=5
and boom! standard form!
I always prefer going from slope-intercept to standard because its easier but its your choice! I hope I helped you!! Please mark brainliest!! Have a supertastic day

Kim works as a server in a restaurant. She is serving the table where a group of her friends are eating. Her friends always tip 15%. If the cost of the meal is $23.60, how much of a tip will Kim earn?
if the bill was $23.60, and the tip was 15%, kim will earn $3.54. the overall total of the meal would be $27.14 :)
Anwser will be $3.54
15% = .15 ( to convert percent to decimal, change the % to . and move the decimal two places to the left)
23.60 * .15 = 3.54

Mr. Ling defined two linear functions. He represented one function with a table of values and graphed the other function, as shown below
Which statement is true about the slope?
F. The slope of the function in the table is equal to the slope of the function in the graph
G. The slope of the function in the table is the opposite of the slope of the function in the graph.
H. The slope of the function in the table is the reciprocal of the slope of the function in the graph.
J. The slope of the function in the table is the opposite reciprocal of the slope of the function in the graph.
PLEASE HELP I REALLY NEED IT TO PASS ALGEBRA!!!! please please help
Answer:
G. The slope of the function in the table is the opposite of the slope of the function in the graph.
Step-by-step explanation:
Let's calculate the the slope of the function represented by values on a table and also the function represented on a graph.
Slope of the function represented by the table:
Use any two pairs. Let's use (1, 1) and (2, 4).
[tex] slope(m) = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{4 - 1}{2 - 1} = \frac{3}{1} = 3 [/tex]
The slope of the linear function represented by the table of values is 3.
Slope of the function represented by the graph:
Use any the coordinates of any two points on the line graph. Let's use (0, 4) and (1, 1).
[tex] slope(m) = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{1 - 4}{1 - 0} = \frac{-3}{1} = -3 [/tex]
Therefore, the statement that is correct is:
"G. The slope of the function in the table is the opposite of the slope of the function in the graph."
3 is the opposite of -3.

Answer:
5.099
Step-by-step explanation:
Write an equation for a line that is parallel to 9x + 3y = 8 and passes through the point (-1, -4).
Answer:
y = -3x - 7
Step-by-step explanation:
turn into slope-intercept form:
9x + 3y = 8: subtract 9x to isolate y
3y = -9x + 8: divide by three to isolate again
y = -3x + 8/3 (line): Substitute y and x and replace 8/3 with b
-4 = -3(-1) + b: distribute
-4 = 3 +b: isolate b by subtracting 3
-7 = b
Substitute for b in original equation
y = -3x - 7
Answer:
y=-3x-7
Step-by-step explanation:
First you need to change the equation to slope intercept form. so the equation becomes y=-3x+8/3. now you change it point slope, y-y1=m(x-x1), y--4=-3(x--1), which also becomes y+4=-3(x+1), now you multiply. -3 times x and 1 which makes the equation, y+4= -3x+-3, then subtract from each side since its a positive number. so now the equation y= -3x-7
