Mrs. Rodsan has found a summer job driving the ice cream truck! She keeps track of the data on selling ice cream and finds that the number of sponge
bob pops sold in the first 5 hours she drives the truck can be modeled by
f(x) = 2(x - 2) + 1, where x is the number of hours. After the first 5
hours the number of sponge bob pops sold can be modeled by f (x) = 3x.
How many more spongebob pops will she sell driving for 7 hours than driving
for 4 hours? Show all work?

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
