Answer:

x = 4

Step-by-step explanation:

The steps we need to take:

1. Simplify left side.

2. Separate the variable and its coefficient from constants

3. Divide both sides by the coefficient to find "x

1) Simplify left side.

5(3x - 4) + 12 = 52

15x - 20 + 12 = 52

15x - 8 = 52

2) Separate the variable and its coefficient from constants by adding 8 to both sides.

15x - 8 + 8 = 52 + 8

15x = 60

3) Divide both sides by the coefficient to find x. (the coefficient is the number that comes before the variable)

15x / 15 = 60 / 15

x = 4

What would be the slope for (-4,-7) (-6,4)

Sliva [168]

Answer: $\frac{11}{-2}$

Step-by-step explanation:

ok so I'm going to try to show it the best c an

m = slope

the equation you use is

$\frac{y2-y1}{x2-x1} =$ m

so when using that formula with the cords, you get

$\frac{4-(-7)}{-6-(-4)}$

and then subtract everything and you'll get

$\frac{11}{-2}$

To subtract two rational expressions that have a common denominator, you simply _____ the numerators.

Gala2k [10]

The answer is subtract.

For example:

$\frac{3x^2 - 3}{x+2} - \frac{x^2+6}{x+2}$

$\frac{3x^2 - 3-x^2-6}{x+2}$

$\frac{2x^2-9}{x+2}$
