-10x - 135 = 117 + 2x A. 25 B. -18 C. -21 D. 22 Helps pls

Lina20 [59]

Answer:

Step-by-step explanation:

Add 10x to both sides:

-10x - 135 = 117 + 2x

-10x - 135 + 10x = 117 + 2x + 10x

-135 = 117 + 12x

Subtract 117 from both sides:

-135 - 117 = 117 + 12x - 117

-252 = 12x

Divide both sides by 12:

$\frac{-252}{12} = \frac{12x}{12}$

-21 = x

So the answer is C.

Hope this helps!

How would the domain and range of the function y = one-fourth x minus 6 be determined? Explain.

Liono4ka [1.6K]

Answer:

Domain = ( -∞ , ∞ )

Range = ( ∞ , ∞ )

Step-by-step explanation:

A function is given to us and we need to find the domain and range of the given function .

The function :-

$\rm \implies y = \dfrac{1}{4}x - 6$

Definitions :-

Range :- The range is the set of all valid y values .
Domain :- All real numbers except where the expression is undefined.

In this case, there is no real number that makes the expression undefined. Therefore the domain will be :-

Domain :-

$\rm Domain = ( -\infty , \infty )$

$\rm Domain = \{ x | x \in \mathbb{R} \}$

Range :-

$\rm Range = ( -\infty , \infty )$

$\rm Range = \{ y | y \in \mathbb{R}\}$

If f(x) = 3^+ 10 and g(x) = 2x - 4, find (f - g)(x).

just olya [345]

Answer:

3^x -2x +14

Step-by-step explanation:

I will assume you mean 3^x in the function f(x)

f(x) = 3^x+ 10

g(x) = 2x - 4

(f - g)(x) = 3^x+ 10 - (2x - 4)

Distribute the minus sign

= 3^x+ 10 - 2x + 4

= 3^x -2x +14
