Answer:
Step-by-step explanation:
Let height of a banner be , then we know that this is
of the length
of the banner; so we have
.
Now we can rearrange this equation to solve for the length of the banner given it's height:
So there we have it!
If the banner is 5 ft tall, then it's length will be:
Answer:
26 pounds
Step-by-step explanation:
let x be the number of pounds.
then
5.99+0.65x=22.89
0.65 x=22.89-5.99=16.90
Answer:
(59) = 20
Step-by-step explanation:
(x) is the inverse of f(x)
to find the inverse function, let f(x) = y and rearrange to make x the subject.
y = 3x - 1 ( add 1 to both sides )
y + 1 = 3x ( divide both sides by 3 )
= x
change y back into terms of x with x = (x) , then
(x) =
, then
(59) =
=
= 20
