The football team needs a combined total of 168 T-shirts for field day. The number of
extra large T-shirts needed is three times the
number of large T-shirts needed. Based on
this information, would it be reasonable for
the football coach to order 40 large T-shirts
and 128 extra large T-shirts?

No.

Step-by-step explanation:

40 * 3 is 120 not 128, so if he ordered 42 Large T-shirts instead he would have 126 XL shirts and 126 + 42 is 168, the correct number

the system of inequity is

step-by-step explanation:

from the given graph it is noticed that we have two related lines. one is solid and another is dashed.

if a line passing through two points, then the equation of line is

the solid line passing through the points (0,4) and (4,0).

the related equation of solid line is .

similarly, find the related equation of dashed line. the dashed liune passing through the points (0,0) and (3,1).

the related equation of dashed line is

from the given graph it is noticed that the point (0,1) lies on the shaded region, therefore the point (0,1) must be satisfied by the related equations.

check the related equations by the point (0,1).

this statement is true if the sign of inequality is < instead of equality. since it is an solid line therefore the sign of inequality will be . the required inequality is

similarly, check the second related equation.

it is a dashed line, so this statement is true if the sign of inequality is > . the required inequality is

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
