Ineed to solve the absolute value for |2x - 7| = |2x + 9| anything will !

-1/2

Step-by-step explanation:

One way: Since both sides have absolute value, you could square both sides to get rid of the absolute value.  This will result in a possible quadratic given the degrees inside the squares; I can already tell you know in this cases the variable squares will cancel since the coefficient of x on both sides inside the | | are the same.

Expand both sides using: .

Subtract on both sides:

Add on both sides:

Subtract on both sides:

Simplify:

Divide both sides by 64:

Reduce the fraction by dividing top and bottom by :

The solution is -1/2.

Let's check it.

So x=-1/2 does check out.

Another way: This is for all the people who hate quadratics.

We could consider cases.  These cases must be checked.

is

Let's solve all four of these and then check the solutions.

2x-7=2x+9

Subtract 2x on both sides:

-7=9 (not possible)

Moving on.

2x-7=-(2x+9)

Distribute:

2x-7=-2x-9

Add 2x on both sides:

4x-7=-9

Add 7 on both sides

4x=-2

Divide both sides by 4:

x=-2/4

Simplify:

x=-1/2

We already checked this from before.

its d. the first coordintaes are 10,32

step-by-step explanation:

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true
