Answer:

x = -8

Step-by-step explanation:

-8x + 3(x - 5) = 25

Distribute the 3 into the (x - 5).

-8x + 3x - 15 = 25

Combine like terms.

-5x - 15 = 25

Add 15 to both sides.

-5x = 40

Divide both sides by -5.

x = -8.

Proof:

-8x + 3(x - 5) = 25

Substitute variable.

-8(-8) + 3((-8) - 5) = 25

Subtract inside parenthesis.

-8(-8) + 3(-13) = 25

Multiply -8 and -8.

64 + 3(-13) = 25

Multiply 3 and -13.

64 + (-39) = 25

Add 64 and -39.

25 = 25

How do I create and graph equations in two variables?

lina2011 [118]

Substitute x=0 in the equation and find the value for y that makes the resulting equation true. For example, in the equation x-2y=2, when x=0, the equation becomes -2y=2. Since y=-1 makes this equation true, one point on the line is (0,-1)

Answer:

a. Ans;

$(4a {b}^{5} )^{4} = ({4})^{4} ( {a})^{4} ({b}^{5} )^{4} = 256 {a}^{4} {b}^{20}$

__o__o__

b. Ans;

$2 {p}^{ \frac{1}{3} } = 6 \\ 2 \sqrt[3]{p} = 6 \\ \\ \sqrt[3]{p} = \frac{6}{2} \\ \\ \sqrt[3]{p} = 3 \\ \\( {p}^{ \frac{1}{3} }) ^{3} = {(3)}^{3} \\ \\ p = {3}^{3} \\ \\ p = 27$
