Below are the graphs of y = | x | and y = | x | - 9 . how are the graphs related?

a. the graphs have the same shape. the y-intercept of y = | x | is 0 and the x-intercept of the second graph is –9.

b. the graphs have the same y-intercept. the second graph is steeper than y = | x | .

c. the two graphs are the same.

d. the graphs have the same shape. the y-intercept of y = | x | is 0 and the y-intercept of the second graph is –9.

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!

this is a direct variation proportion. y = kx

y is the total amount due, k is the constant of variation, and x is the number of texts sent.

plug in the 3.20 and the 16 to solve for the "k". this is the constant of proportionality. it is the value that will not change.

3.20 = k(16). solving you get $.20 per text.

the equation would then be y = .20x
