Substitute the variable's values for the variables themselves.

5(x + 8) + x + y =>
5(3 + 8) + 3 + 30

Use the order of operations to simplify this expression.

5(3 + 8) + 3 + 30
5(11) + 3 + 30
55 + 3 + 30
58 + 30
88

So, the answer is 88.

The owner of a video game store creates the expression −2x2 + 24x + 174 to represent the store's weekly profit in dollars, where

Semmy [17]

Answer:

$-2(x-6)^2+246$ , x = $6

Step-by-step explanation:

The expression $-2x^2+24x+174$ to represent the store's weekly profit in dollars, where x represents the price of a new video game.

Let $f(x)=-2x^2+24x+174$

We need to rewrite this quadratic function in the vertex form.

$f(x)=-2(x^2-12x)+174$

$f(x)=-2(x^2-12x+36)--2(36)+174$

$f(x)=-2(x^2-12x+36)+72+174$

$f(x)=-2(x-6)^2+246$

The equivalent expression that reveals the video game price that produces the highest weekly profit is $-2(x-6)^2+246$

and the price is $6

Solve the following inequality: –1 6(–1 – 3x) > –39 – 2x

jeka57 [31]

If you would like to solve the inequality <span>–1 + 6 * (–1 – 3x) > –39 – 2x, you can do this using the following steps:

</span>–1 + 6 * (–1 – 3x) > –39 – 2x
-1 - 6 - 18x > -39 - 2x
-7 + 39 > -2x + 18x
32 > 16x
32/16 > x
x < 2

The correct result would be x < 2.
