Answer:

r = 4

General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define equation

-5 + 22 = r - 4 + 3r + 5

Step 2: Solve for r

Combine like terms: 17 = 4r + 1
Subtract 1 on both sides: 16 = 4r
Divide 4 on both sides: 4 = r
Rewrite: r = 4

Step 3: Check

Plug in r to verify it's a solution.

Substitute: -5 + 22 = 4 - 4 + 3(4) + 5
Add/Subtract: 17 = 3(4) + 5
Multiply: 17 = 12 + 5
Add: 17 = 17

Find the slope and the y-intercept of the of the linear equation. 0=2-3y+12x

andrew11 [14]

The slope is 4 and the y-intercept is $\frac{2}{3}$

Step-by-step explanation:

The general form of a linear equation is Ax + By + C = 0, where

A is the coefficient of x
B is the coefficient of y
C is the numerical term
A, B, and C are integers
The slope of the line = $\frac{-A}{B}$
The y-intercept = $\frac{-C}{B}$

∵ The linear equation is 0 = 2 - 3y + 12x

- Switch the two sides and arrange the terms as the general

form above

∴ 12x - 3y + 3 = 0

∴ A = 12

∴ B = -3

∴ C = 2

∵ The slope of the line = $\frac{-A}{B}$

- Substitute A by 12 and B by -3

∴ The slope of the line = $\frac{-12}{-3}$

∴ The slope of the line = 4

∵ The y-intercept = $\frac{-C}{B}$

- Substitute C by 2 and B by -3

∴ The y-intercept = $\frac{-2}{-3}$

∴ The y-intercept = $\frac{2}{3}$

The slope is 4 and the y-intercept is $\frac{2}{3}$
