Answer: 3/5
Step-by-step explanation:
First, you need to find the inverse of f(x)=2x+5 .
Then, you'd plug in 8 into that equation, which I got

Answer:
The graph is being stretched vertically, so it will be thinner.
Step-by-step explanation:
g(x) = 8f(x) means that you are multiplying each original y-value by 8, so the graph gets thinner. When there's a number n greater than 1 in front of the function, it's a vertical stretch by n.
There should be 30 cars in the parking lot
Circumference~(pi)(diameter)~28.26
Area~ (pi)(radius)squared~63.59
I believe these are right
Let that certain number be 'n'
50% (n) = 39
50% ⇒ 0.5
0.5 (n) = 39
Divide both sides by 0.5
0.5n = 39
/0.5 /0.5
n = 78.
So that certain number is actually <em><u>78! :)</u></em>
CROSS CHECK:
50% of 78
0.5 × 78
= 39
Hope this helps! :)
