Slope-intercept form can be written as
y = mx + b
From the question above, we should move x to another side (right side), so the left side only contains of y-variable
-3x + 2y = 12
2y = 12 + 3x
To make slope-intercept form, only y is on the left side. We should move the coefficient 2 to the right side.
2y = 12 + 3x
2y = 3x + 12
y = (3x + 12)/2
Simplify the equation
y = (3x + 12)/2
y = (3/2)x + 12/2
y = (3/2)x + 6
This is the final answer ⇒ y = (3/2)x + 6
1. <span>4x=7(x-3) -----> Start with the given.
2. </span><span>4x=7x-21 -----> Distribute 7 by multiplying it to the individual terms inside the parenthesis. 7(x) - 7(3) = 7x -21
3. </span><span>-3x=-21 ------> From step 2, combine like terms by transposing. The equation becomes 4x - 7x = -21. Simplifying, it becomes -3x = -21
4. x = 7 -----> Divide both sides by -3, you get the value o x.
Hope this helps :)</span>
First we do what’s in the parentheses.
7 • 10 - 5 = 70 - 5 = 65
Then we do exponents. We don’t have any so we skip this step.
Then we do multiplication and division.
65 • 0.0007 = 0.0455
We don’t have any addition or subtraction so we skip this step.
The solution is 0.0455.
C. (1.6 , -0.8)
Walkthrough:
The X line is horizontal, and the Y line is vertical. You always want to use the X line before Y
Example: (X , Y) (1.6 , -0.8)
Well first you get N on one side alone,
Multiply it by 7 on both sides
N = -28
That is your answer, N = -28
