The value of f(5) is -37
<em><u>Solution:</u></em>
<em><u>Given function is:</u></em>
We have to find the value of f(5)
To find the value of f(5), we have to substitute x is equal to 5 in given function
Plug in x = 5 in f(x)
Thus value of f(5) is -37
Answer:
x=18
Step-by-step explanation:
We need to find the areas of the rectangles
1st rectangle
A= l*w
A = (2x+4)*9
= 18x+36
2nd rectangle
A = l*w
= 15*(3x-30)
= 45x-450
Since the area of the rectangles are equal, we set these two equations equal
18x+36 = 45x-450
Subtract 18x from each side
18x-18x+36 = 45x-18x-450
36 = 27x-450
Add 450 to each side
36+450 =27x
486 = 27x
Divide by 27 on each side
486/27 = 27x/27
18=x
Y intercept is +1
Slope is 1/2
Y= 1/2x + 1
