Consider the absolute value inequality: |x - 6| > 20. Will the graph of the solutions to the inequality result in an "and" or

Dmitrij [34]

Step-by-step explanation:

Case 1 : |x| > a, => x > a or x < -a

Case 2 : |x| < a, => -a < x < a

Since this question follows Case 1, we will have an "or" inequality.

Hey!

Let's write the problem.
$2x-4-5x=2$
Add like terms...
$-3x-4=2$
Add $4$ to both sides.
$-3x-4+4=2+4$
$-3x=6$
Divide both sides by $-3$ .
$\frac{-3x}{-3}=\frac{6}{-3}$

Our final answer would be,
$x=-2$

Thanks!

So,

5*1.5= 7.5

x= 7.5

All points on a given line have their y-coordinate as 9. What is the equation of this line? A. x + y = 9 B. x – y = 9 C. x = 9 D

Phoenix [80]

D. y = 9 because it has a complete zero slope while the y-intercept of the equation is 9, so the equation is y = 9.
