Tina has been dieting for a total of 13 weeks she lost 3 pounds on the first week of her diet we gained back a pound on the second week on each meaning week of her diet she lost 2 pounds how many pounds has tina lost it all? a.26 lbs b.20 lbs c.22 lbs d.24 lbs

Week 1 she lost 3 pounds

week 2 she gained 1 pound

so in the first 2 weeks she lost 3-1 = 2 pounds total.

13 weeks - 2 weeks = 11 weeks left.

Each of those weeks she lost 2 pounds, so 11 weeks x 2 pounds = 22 total pounds in 11 weeks.

22 pounds +2 pounds = 24 total pounds lost in 13 weeks.

The answer is D.

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

step-by-step explanation:

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.
