Solve the absolute value equation.<br><br> 4 − |x| = 1
Alika [10]

Answer:

x = +3 and -3

Step-by-step explanation:

Start by solving for |x| as normal:

4 - |x| = 1

- |x| = -3 (subtract 4 from both sides)

|x| = 3 (multiply both sides by -1)

the absolute value of x means it will be positive, so you need to recognize that whatever is in the absolute value bars will be made positive.

this means that x = 3 AND -3, because both |3| and |-3| = 3

check your answer by plugging x = 3 and x = -3 back in:

4 - |3| = 1

4 - 3 = 1

1 = 1

and

4 - |-3| = 1

4 - 3 =  1

1 = 1

Write an equation in slope intercept form for the following graph.​
Umnica [9.8K]
Y = -1/2x + 3
Why?
Looking at the line start where the line intercepts the y line, it goes down one over 2 and that’s your slope, the 3 is bc that’s where the line crosses the y line

Answer:Decreasing

Step-by-step explanation:

Focus only on the 8-10 interval for x. Note that for x=8 , y=1, for x=9, y=0 and for x=10, y=-1. Y is obviously decreasing for 8 .
