Use a graphing calculator to approximate the x-intercept of the point where the value of the account would be zero.
Rafael has $1475 in his bank account and makes automatic monthly payments of $230.22 for a
smartphone service plan. If he stops making deposits to that account, when would the automatic
payments make the value of the account zero?
After months, the account will not have enough money left in it to make the next month's
automatic payment.
To the nearest tenth, the x-intercept of the graph of the account's value is

60%

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

show us the triangle so we can answer it

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.
