What is the answer to | 2x + 9 | = 15

x  =  3 &  −

12

Step-by-step explanation:

Find all solutions for  x  by breaking the absolute value into the positive and negative components.

Let's solve your equation step-by-step.

|2x+9|=15  Solve Absolute Value.

|2x+9|=15

We know either 2x + 9 = 15 or 2x + 9 = −15

2x + 9 = 15(Possibility 1)

2x + 9 − 9 = 15 − 9(Subtract 9 from both sides)

2x=6  (Divide both sides by 2)

x=3  

2x + 9 = −15(Possibility 2)

2x + 9 − 9 = −15 − 9(Subtract 9 from both sides)

2x=−24  (Divide both sides by 2)

x=−12

x=3 or x=−12

step-by-step explanation:

the required function is .

step-by-step explanation:

from the given table it is noticed that the graph passing through (-3,7), (0,4), (3,1) and (8,-4).

it is a linear function because the value of y is decrease by one as the value of x increase by 1.

the slope of the function is

the slope of the function is -1 and the y-intercept is 4.

the slope intercept form is

where, m is slope and b is y-intercept.

therefore the required function is . the graph of this function is shown below.
