Answer:

Simplifying

10x + -2 = 118

Reorder the terms:

-2 + 10x = 118

Solving

-2 + 10x = 118

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '2' to each side of the equation.

-2 + 2 + 10x = 118 + 2

Combine like terms: -2 + 2 = 0

0 + 10x = 118 + 2

10x = 118 + 2

Combine like terms: 118 + 2 = 120

Combine like terms: 118 + 2 = 12010x = 120

Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.

Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.x = 12

Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.x = 12Simplifying

Combine like terms: 118 + 2 = 12010x = 120Divide each side by '10'.x = 12Simplifyingx = 12

What is the value of the power a if 5 to the power of a is equal to 1/125

padilas [110]

First of all, you should know/notice that

$125=5^3$

You should also know how negative exponents work:

$a^{-m}=\dfrac{1}{a^m}$

So, if you wanted

$5^x=125$

the answer would be x=3, but since you want 125 to be at the denominator, the answer is x=-3:

$5^{-3}=\dfrac{1}{5^3}=\dfrac{1}{125}$

Answer:

$\square\quad{y=\dfrac{1}{2}x+4}\\\\\square\quad{\dfrac{y-5}{x-2}=\dfrac{1}{2}}$

Step-by-step explanation:

The slope of a line is the same everywhere, so an equation can be written making use of that fact.

$\dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}\\\\\dfrac{y-5}{x-2}=\dfrac{7-5}{6-2}=\dfrac{2}{4}\\\\\boxed{\dfrac{y-5}{x-2}=\dfrac{1}{2}}$

Cross-multiplying gives ...

2(y -5) = x -2

2y -10 = x -2 . . . eliminate parentheses

2y = x +8 . . . . . . . add 10; next, divide by 2

$\boxed{y=\dfrac{1}{2}x+4}$

These equations match choices B and D.
