Answer:
and 
Step-by-step explanation:
To find the inverse, we will set f(x) equal to y, swap the x and y values, and then solve for y.
Given:
f(x) = x² - 25
Equal to y:
y = x² - 25
Swamp x and y values:
x = y² - 25
Add 25 to both sides of the equation:
y² = x + 25
Square root both sides of the equation:

Step-by-step explanation:
i think its gonna be b because i did the math and got thr answer b
Zero because you combine 12z and 15z because they are like terms giving you 27z. The equation now looks like 27z-6=27z-5. Subtract 27z on both sides leaving you -6=-5 which is false. So the equation has 0 solutions.
Answer:
c = 7.
Step-by-step explanation:
The slope = (y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are the 2 points.
So here we have the equation
- 3 = (3 - (-3)) /(5 - c)
-3 = 6 / (5 - c) Cross multiply:
-3(5 - c) = 6
-15 + 3c = 6
3c = 6 + 15
3c = 21
c = 7.
It looks like the shadow for the lamp only went up 8 feet so I assuming it would go up 8 feet as well for the guy
