Solve for x: 2x + 13 = 8x - 41

kherson [118]

Answer:

9 is your answer for x.

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. Do the opposite of PEMDAS.

PEMDAS is the order of operations, & =

Parenthesis

Exponent (& Roots)

Multiplication

Division

Addition

Subtraction

First, subtract 13 & 8x from both sides:

2x (-8x) + 13 (-13) = 8x (-8x) - 41 (-13)

2x - 8x = -41 - 13

Simplify. Combine like terms:

-6x = -54

Isolate the variable, x. Divide -6 from both sides:

(-6x)/-6 = (-54)/-6

x = (-54)/(-6)

x = 9

x = 9 is your answer.

What is the slope between the points (5,-4) and (-3,4) <br> -1<br> 4<br> 0<br> 1

kumpel [21]

Answer:

The answer is -1.

Step-by-step explanation:

You have to apply gradient formula :

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

So you will have to substitute the coordinates into the equation. Let (x1,y1) be (-3,4) and (x2,y2) be (5,-4) :

$m = \frac{ - 4 - 4}{5 - ( - 3)}$

$m = \frac{ - 8}{8}$

$m = - 1$
