malia works at a movie theater and is paid hourly. one month, she earned $388.80. the total amount she earns can be found using the equation y = 8.1x, where x is the number of hours she works and y is the total amount she earns in dollars.

bill works at a golf course and is also paid hourly. the table shows the total amount he is paid for different numbers of hours worked.

number of hours total amount earned
18 $144.90
28 $225.40
35 $281.75

malia's unit rate than bill's is greater .

a greater lesser

b $8.05 per hour $8.10 per hour $388.80 per hour $402.50 per hour

c $8.05 per hour $8.10 per hour $388.80 per hour $402.50 per hour

b and c are supposed to be the same.

Malia : y = 8.1x

Malia =  8.10 hours worked

Bill : if he earned 144.90 for working 18 hrs144.90/18 = 8.05 per hr worked.

so Malia makes 5 cents more per hours worked.

(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
