Which of the following shows the solution to the inequality

otez555 [7]

Answer:

I got x = 1

Step-by-step explanation:

First to isolate the variable you add 3 to both sides which will give you 1/2x is less than or equal to 2. Then divide both sides by 1/2 and you will get x = 1. To check the answer I just did:

$1/2(1) -3 \leq -1\\1/2 -3\leq -1\\-2.5\leq -1$

And since -2.5 is less than -1 this statement is true. x does in fact equal 1

Answer:

$f(x - 4) = x^2 - 6x+ 8$

Step-by-step explanation:

Given

$f(x) = x^2 + 2x$

Required

Find f(x - 4)

Substitute x - 4 for x

$f(x - 4) = (x- 4)^2 + 2(x - 4)$

Expand

$f(x - 4) = x^2 - 8x + 16 + 2x - 8$

Collect like terms

$f(x - 4) = x^2 - 8x + 2x+ 16 - 8$

$f(x - 4) = x^2 - 6x+ 8$
