Parabola skate rental rents skate boards for $4.50 per hour with a rental fee of $35. arc of hawk skate rental rents skate boards for $5.25 per hour with a rental fee of $25. rate of change

Step-by-step explanation:

Parabola Skate Rental:   4.50x + 35

Arc Hawk Skate Rental:  5.25x + 25

If you want to know when their cost will be the same, set the equations equal to each other.

5.25x + 25 = 4.50x + 35

0.75x + 25 = 35          subtracted 4.50x from both sides

0.75x = 10           subtracted 25 from both sides          

             divided both sides by 0.75

     x =        simplified the fraction

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
