The storm lasted a the total of nine hours. It snowed at a rate of 1 in./h during the first two hours. The snow continues for the next six hours falling at a rate of 2 in./h and finally reduced to 1 in./h for the last hour after which completely stop snowing. Which graph shows the snowball over the nine hour period

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

faster, im not sure why but i know it is faster

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
