11.4.3 Quiz: Solving Inequalities Question 2 of 10
Solve - 2x - 6 > x + 9.
A. 3 > -3
B. 2 > -5
C. x < -5
D. x < -3

C

Step-by-step explanation:

-2x - 6 > x + 9

-3x > 15

x < -5

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!
