Answer: \Large\boxed{f(x-1)=x}

Step-by-step explanation:

<u>Given function</u>

f(x + 1) = x + 2

<u>Isolate [ x + 1 ] on the right-hand side</u>

f(x + 1) = x + 1 + 1

f(x + 1) = (x + 1) + 1

<u />

<u>Substitute [ x + 1 ] with x</u>

f(x) = x + 1

<u>Substitute [ x ] with [ x - 1 ]</u>

f(x - 1) = (x - 1) + 1

\Large\boxed{f(x-1)=x}

Hope this helps!! :)

Find the equation of the line through the points (-2,5) and (3,-10). Give your answer in slope-intercept form.
Brilliant_brown [7]
m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{-10 - 5}{3 - (-2)} = \frac{-15}{3 + 2} = \frac{-15}{5} = -3

y - y₁ = m(x - x₁)
 y - 5 = -3(x - (-2))
 y - 5 = -3(x + 2)
 y - 5 = -3(x) - 3(2)
 y - 5 = -3x - 6
   + 5         + 5
      y = -3x - 1

Alex has 520 yards of fencing to enclose a rectangular area.
Pavlova-9 [17]
<span>Perimeter =2w+2L= 520.
We can solve this by understanding that the area is maximized by a square
Therefore L=w.

p=2w+2w=520=4w
w=130

Area
 
A=wL=130(130)= 16900 square yards</span>
