Answer:

I got this. Use the order PEMDAS search Up if you don’t know what it means.

Step-by-step explanation:

Start with What’s inside the parentheses

(X - 3) = 3x

(X + 5) = 5x

The divide.

How to divide it - The number coefficients are reduced the same as in simple fractions. When dividing variables, you write the problem as a fraction. Then, using the greatest common factor, you divide the numbers and reduce. You use the rules of exponents to divide variables that are the same — so you subtract the powers.

The equation 3x + 6 = 12 involves two operations performed on x: multiplication by 3 followed by addition of 6. What operations

BlackZzzverrR [31]

3x + 6 = 12
First operation was subtraction (subtracting 6 to leave 3x alone)
Second operation was division (Dividing 3 from 3x to isolare x)

3x + 6 = 12
3x + 6 -(6) = 12 - 6
3x = 6

$\frac{3x}{3}$ = $\frac{6}{3}$
3 and 3 cancels out
x = 2

What is the slope of the line that passes through the points (7,26) and (12, -39)?

Elena-2011 [213]

The slope (m) = -13.

We can use the slope formula:

m = (y2 - y1) / (x2 - x1)

Let (x1, y1) = (7, 26)
(x2, y2) = (12, -39)

Plug in the values into the formula:

m = (y2 - y1) / (x2 - x1)
m = (-39 - 26) / (12 - 7)

m = -65/5

m = -13

What is the equation of the line that passes through the points (-6,2) and (4,-3)

stich3 [128]

Answer:

The equation is: 9x-y = 56

Step-by-step explanation:

Given two point: (x,y) = (-6,2)

(x,y) = (4,-3)

Now, to find the slope of the line:

Slope = y1-y2/x1-x2 => 2-4/-6-(-3) = -1/9

Then, the equation of the line passing through a point:

=> y-y1 = m(x-x1)

=> y-2 = -1/9(x-6)

=> 1(y-2) = -9(x-6)

=> y-2 = -9x+54

=> 9x-y = 56
