Simplify the expression 9+1/2(7n-26)-8.2

-122/10 -35/10n

Step-by-step explanation:

P E M/D A/S

1) Solve anything in ()s first. Since nothing can be solved in ()s, move onto step 2.

2) Exponents. Since none of the numbers have exponents, move onto step 3.

3) Multiply/Divide:

       1

9 + (7n-26) -8.2

      2

= 9 + 7/2n - 13 -8.2

4) Add/Subtract:

9 + 3 1/2n -13 - 8.2

= -4 + 3 1/2 -8.2

*Convert -8.2 to a fraction, then get the denominators to match:

-8 2/10 = -82/10

7/2n = 35/10n

-4 = -40/10

*Now, you can add theses numbers together to get the final

-40/10 + 35/10n -82/10

= -122/10 -35/10n

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
