Sergio039 [100]2 years ago
6 0

Answer:

D) 3

Step-by-step explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtractions

~

First, subtract 4 from both sides of the equation:

2x + 4 (-4) = 10 (-4)

2x = 10 - 4

2x = 6

Next, divide 2 from both sides of the equation:

(2x)/2 = (6)/2

x = 6/2

x = 3

D) 3 is your answer.

(3,-2);slope 1/3 what is the answer?
wolverine [178]

Answer:

y = \frac{1}{3} x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = \frac{1}{3} , then

y = \frac{1}{3} x + c ← is the partial equation

To find c substitute (3, - 2) into the partial equation

- 2 = 1 + c ⇒ c = - 2 - 1 = - 3

y = \frac{1}{3} x - 3 ← equation of line
