The newberg tigers are having team shirts made. one option is to pay reggie's tees a $40 setup fee and then buy the shirts for $4 each. another option is to go to city printing, paying $20 for a setup fee and an additional $8 per shirt. the team parent in charge of the project notices that, with a certain number of shirts, the two options have the same cost. how many shirts is that?

answer: a

step-by-step explanation:

step-by-step explanation:

it will be a cylinder. with a diameter of 8 and 4 single pieces high

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
