I think it’s 5. I’m not sure
We know that the domain is actually the number of rolls
that she gets because it is the input variable in the equation f (r) = 40 r + 26. The number of rolls that
she can get can never be a negative number nor a zero nor a decimal number.
However she can only get up to 10 rolls. Therefore the answer is:
all integers from 1 to 10, inclusive
Answer:
f(1) = 3
Step-by-step explanation:
f(t) = t² - 1t + 3
we want to find f(1)
all we have to do is replace the t's with 1 and evaluate
f(1) = (1)² - 1(1) + 3
evaluate exponent 1² = 1
f(1) = 1 - 1(1) + 3
multiply
f(1) = 1 - 1 + 3
subtract
f(1) = 3

Answer:
x + 20 = area
Step-by-step explanation:
You need to recall the equation for a rectangle:
Width x Length = Area
So simply plug the values into this:
(0.5x+10) * 6
(0.5x * 6) + (10 * 6)
= 3x + 60
Simplified down by dividing by three:
= area
<h3>x + 20 = area</h3>
