4 A highway construction crew is using a road stripe painting truck that holds a maximum of
330 gallons of paint. The graph shows the paint
remaining in the holding tank after x number of
miles of stripe painted.

What is the domain of the graphed situation?
F All real numbers less than or equal to 120.
G All real numbers less than or equal to 330.
H All real numbers greater than or equal to 0
and less than or equal to 120.
J All real numbers greater than or equal to 0
and less than or equal to 330.

answer: i guess 5 units?

step-by-step explanation:

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

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

- both graphs increase on their domain.

- the graphs of both functions have the same x-intercept.

- neither graph has a y-intercept.
