Answer:
1/25
Step-by-step explanation:
substitute -2 where there are x
f(x) = 5^x
f(-2) = 5^(-2)
f(-2) = 1/(5^2)
f(-2) = 1/25
Not entirely sure about question a... but b would be (lol) 27

Answer:
21m
Step-by-step explanation:
So for the rectangle, do 5*6, and you will get the area of the whole backyard. Then to get the area of the grass, you do 3*3 to get 9.
Finally, to get the cement, you subtract the area of the grass from the area of the whole backyard so 30-9 to get 21.
5*6=30
3*3=9
30-9+21
Please mark brainliest if you can!
Start with the first sentence, and the definition of the area of a rectangle:
l * w = 36
Rewrite the equation to get
l = 36 / w
or
w = 36 / l
Either one shows the inverse relationship between w and l.
Assuming the last part wants you to write an equation for an x-y graph, the equation would be
y = 36 / x
