Andrew [12]

Answer:

y = -2/7x - 22/7

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$

Slope-Intercept Form: y = mx + b

m - slope

b - y-intercept

Step-by-step explanation:

Step 1: Define

Point (-4, -2)

Point (3, -4)

Step 2: Find slope m

Substitute: $m=\frac{-4+2}{3+4}$
Add: $m=\frac{-2}{7}$

Step 3: Find y-intercept b

Define: y = -2/7x + b
Substitute: -4 = -2/7(3) + b
Multiply: -4 = -6/7 + b
Isolate b: -22/7 = b
Rewrite: b = -22/7

Step 4: Write linear equation

y = -2/7x - 22/7

PLEASE HELP AND EXPLAIN!

Neko [114]

Answer:

12 years old.

Step-by-step explanation:

1) 2x+x=18

2) Now solve 2x+x=18

Add alike terms

3x=18

Now divide both sides by 3 (3x/3 and 18/3)

x=6

So Hannah is 6 years old. Her sister must be 12.
