What is the slope of a line perpendicular to the line passing through (-23, 8) and (12, -17)

Radda [10]

Answer:

$m=\frac{7}{5}$

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 of a perpendicular line is the negative reciprocal of the original

Step-by-step explanation:

Step 1: Define

Point (-23, 8)

Point (12, -17)

Step 2: Find slope m

Substitute: $m=\frac{-17-8}{12+23}$
Subtract/Add: $m=\frac{-25}{35}$
Simplify: $m=\frac{-5}{7}$

Step 3: Find perpendicular slope m

Take negative: $m=\frac{5}{7}$
Take reciprocal: $m=\frac{7}{5}$

And we have our final answer!

What is the solution to the equation 4x + 2 = x3? (Round to the nearest tenth).

frutty [35]

Answer:

X = -2

Step-by-step explanation:

4x + 2 = x3

Subtract 2 from both sides: 4x = x3 -2

Subtract x3 from both sides: 4x - 3x = -2

This leaves 1x = -2 which can also be written as x = -2

x = -2
