At Plumbers “R” Us, the cost of the service call is $50 for him to show up at your house, plus an additional $ 15 per hour PLS GIVE INDEPENDENT VARIABLE AND DEPENDENT

15h + 50

Step-by-step explanation:

Lets use "h" for hours.

50 is left alone and added at the end since its just one fee. Now since 15 is per hour and we don't know how long the plumber will be there we need a variable so 15h.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

step-by-step explanation:

2*5=10

4*15=60

60+10=
