if x increases by 51, f (x) increases by 9.
<u>Step-by-step explanation:</u>
Given function:
The above equation would have a constant slope as it seems to be a linear function. ‘x’, the coefficient of the variable x is the slope of the function. Here,
The rate of change of the function with respect to x referred as the slope of the function. Thus,
Given, x increases by 51. So, we have
Now solve for ΔF,
Thus, we have obtained that if x increases by 51, f (x) increases by 9.

➷ Just substitute the value 5 into everywhere you see 'x':
3(5) + 2
Now solve:
f(5) = 17

Answer: B.) -4+3
Step-by-step explanation:
The model represents "-4+3" because the blue arrow (top) stops at 3 which is a positive and the red arrow (bottom) stops at -4 which is a negative.
Answer:
h = 13cm and b= 54cm.
Step-by-step explanation:
We have that the area and the base is two centimeters longer than four times the height, that is
where b is the base and h the height. Now, the area is
.
Now, we are going to use the general formula to solve quadratic ecuations:
where a=4, b= 2 and c= -702.
or
As we are searching for the lenght, we choose the positive result:
.
Take the number "of" divided by the other number then multiply it by 100% to get the percentage.
(21/33.5) ×100%= 62%
