where do y = -x + 8 and y = x - 2 intersect
Answer:
(5,3)
Step-by-step explanation:
To find where two lines intersect you let them equal to each other.
-x + 8 = x -2
Add 2 on both side
-x + 10 = x
Add x on both sides
10 = 2x
Divide 2 on both sides
5 = x
Now plug x into both equations
y = -5 + 8 = 3
y = 5 - 2 = 3
so y = 3
The point they intersect is (5,3)

The width of a rectangle is 7x – 9.5 feet and the length is 9.5x + 10 feet. Find the perimeter of the rectangle.
Answer:
33x + 1
Step-by-step explanation:
Perimeter of a rectangle: P = 2(l + w) OR P = 2(l) + 2(w)length (l) = 9.5x + 10width (w) = 7x - 9.5P = 2(l + w)
P = 2(9.5x + 10) + 2(7x - 9.5)
P = 19x + 20 + 14x - 19
P = 19x + 14x + 20 - 19
P = 33x + 1

What is the area of this figure?
Select from the drop-down menu to correctly complete the statement.
The area of the figure is 'blank' cm².
Answer:
The area is 146cm squared
Step-by-step explanation:
Starting with the top portion, The formula for the area of a trapezoid is a = (base 1 + base 2) / 2 * h | (14 + 4) /2 *10 = 90.
Now for the bottom part, We know that the height of the top of the figure is 10 and that the overall figure height is 18. To find the height of the triangle at the bottom we would do 18 - 10 = 8.
The formula for finding the area of a triangle is b x h / 2 = a. 14 * 8 / 2 = 56.
Finally, we add our results. 90+56=146.

An elevator at a department store must carry fewer than 17 people at a time. An elevator operator is present in the elevator at all times. If x customers can travel in the elevator with the elevator operator, which inequality represents this situation?
A.
x + 1 < 17
B.
x > 18
C.
x + 1< 16
D.
x < 17
E.
x + 1 > 18
Answer:
A. x + 1 < 17
Step-by-step explanation:
An elevator at a department store must carry fewer than 17 people at a time. An elevator operator is present in the elevator at all times. If x customers can travel in the elevator with the elevator operator, which inequality represents this situation?
x = customers
1 = the elevator operator
< 17 = the amount of people that can be in the elevator at a time
Together, we get our inequality:
x + 1 < 17
The customers + the operator in the elevator should not be greater than 17.

15 point reward + brainliest for the correct answer <3
Answer:
y = 3n - 2
Step-by-step explanation:
so to find the slope or rate of change we use the equation
y 2 - y1 / x2 - x1
soo lets use the points
(1, 1) and (2, 4)
4 - 1/ 2 - 1
3/1
3
y = 3n + b
now we substitute a point we did not use yet
(3, 7)
7 = 3(3) + b
7 = 9 + b
b = -2
y = 3n - 2
now check
(4,10)
10 = 3(4) - 2 ?
10 = 12 - 2 ?
10 = 10
Answer:
y = 3n - 2
Step-by-step explanation:
y = mx + b or y = nx + b
Where m or n represents the slope
[tex]m\ or\ n=\frac{y_2-y_1}{x_2-x_1} \\\\m\ or\ n=\frac{4-1}{2-1} \\\\m\ or\ n=\frac{3}{1} \\\\m\ or\ n=3[/tex]
y = 3n + b
(n, y) ==> (2, 4)
y = 3n + b
4 = 3(2) + b
4 = 6 + b
-6 -6
-2 = b
y = 3n - 2
Check your answer using (2, 4):
y = 3n - 2
4 = 3(2) - 2
4 = 6 -2
4 =4
This statement is correct
Hope this helps!
1). y=x;(2,3) Tell whether the ordered pair is a solution of the equation. 2) Y=3x -2; (1,1)
Answer:
1) no, (2,3) is not a solution of y=x.
2) yes, (1,1) is a solution of y=3x-2
Step-by-step explanation:
When you have a point, the first number is x and the second number is y, (x,y).
If you substitute the numbers in for x and y, you will get a true statement if the point is a solution.
Look at y = x, put in 2 for x and 3 for y.
You get 3 = 2, that's false. So (2,3) is NOT a solution of y = x.
Then consider
y = 3x - 2; fill in 1 for x and 1 for y
You get
1 = 3(1) - 2
1 = 1 , a true statement. So (1,1) IS a solution.
Answer:
(2, 3) is not an ordered pair for y = 3x - 2.
Step-by-step explanation:
(2,3)
y = 3x - 2
3 = 3(2) - 2
3 = 6 - 2
3 = 4
This means that (2, 3) is not an ordered pair for y = 3x - 2.
