Answer:
As shown in picture:
A(-4, 1)
Z(-2, 3)
P(3, -4)
The length of AZ is calculated by:
L = sqrt((-4 - -2)^2 + (1 - 3)^2) = 2.83
The length of AP is calculated by:
L = sqrt((3 - -4)^2 + (-4 - 1)^2) = 8.60
THe length of ZP is calculated by:
L = sqrt((3 - -2)^2 + (-4 - 3)^2) = 8.60
=>Perimeter of triangle AZP is calculated by:
P = AZ + AP + ZP = 2.83 + 8.60 + 8.60 = 20.3
Hope this helps!

To find the inverse we swap y and x and solve for y:
x = 9y + 15
x - 15 = 9y
y = (x-15)/9
Last choice
Answer:
Step-by-step explanation:
The zero of a function is also known as the x-intercept of a function. The x-intercept of a function exists where y = 0. So we will begin by setting each of those lines = 0:
4x - 20 = 0 and -1/2x + k = 0 and then solve each for x:
4x = 20 so
x = 5 and
-1/2x = -k and
1/2x = k so
x = 2k. Now we set the 2 x expressions equal to each other and solve for k:
5 = 2k so
k = 5/2
It would reflect over the x-axis and then reflect over the y-axis
Answer and Explanation:
Suppose Waheeda needs x more dollars.
Right now, she has $15. She needs x more, so we add x to 15. The end result we hope to have is $75. So, the equation is:
x + 15 = 75
To solve, we simply subtract 15 from both sides: x = 75 - 15 = 60
Thus, she still needs $60.
Hope this helps!
