-8x-27=-7\left(1+2x\right)+2x

Darina [25.2K]

Answer:

$x=5$

Step-by-step explanation:

$-8x-27=-7\left(1+2x\right)+2x$

Expand:

$-8x-27=-7\times 1-7\times 2x+2x$

$-8x-27=-7-12x$

Add 27 to both sides:

$-8x-27+27=-7-12x+27$

$-8x=-12x+20$

Add 12x to both sides:

$-8x+12x=-12x+20+12x$

$4x=20$

Divide both sides by 4:

$\frac{4x}{4}=\frac{20}{4}$

$x=5$

Multiply or divide the following expression: Reduce all answers to lowest terms. Factor the following completely.

Semmy [17]

A function assigns the values. The value of f(-3) and f(3) + f(-3) is 8 and -8, respectively.

<h3>What is a Function?</h3>

A function assigns the value of each element of one set to the other specific element of another set.

Given the function f(x)=-x²-4x+5, therefore, the value of f(x) when the value of x is -3 is,

f(-3) = -(-3)² - 4(-3) + 5

f(-3) = -9 + 12 + 5

f(-3) = 8

Now, the value of f(x) when the value of x is 3 is,

f(3) = -(3)²-4(3)+5

f(3) = - 9 - 12 + 5

f(3) = -16

further, the value of f(3) + f(-3) is,

f(3) + f(-3) = -16 + 8

f(3) + f(-3) = -8

Hence, the value of f(-3) and f(3) + f(-3) is 8 and -8, respectively.

Simplify the expression:

Lelu [443]

$\cfrac{(12-5)^7}{\left((3+4)^2\right)^2}= \cfrac{7^7}{(7^2)^2} =\cfrac{7^7}{7^4}=7^{7-4}=7^3=343$
