Membership Fitness Charges:   $30.00  per Month

All Day Fitness Club Charges:    $22.00  per Month

Initiation Fee :     $80.00  


Equation:

30T         =        22T           +      80      ========>     T         =        10 Months

Lets solve your equation step-by-step.

30t        =        22t         +        80

Step 1: Subtract 22t from both sides.

30t      −         22t       =       22t        +       80       −       22t

8t          =          80

Step 2: Divide both sides by 8.

8t / 8                       =            80 / 8

Answer   ==========>            T             =              10 Months Will the total amount paid to the two fitness clubs will be the same.





Hope that helps!!!!!!!!!!!                                          : )

A quadratic equation has the solutions x- -5 and x=4 What are the x-intercepts of the graph of the function?
DedPeter [7]
Answer:
(-4, 0) and (1, 0)

Step-by-step explanation:
"Solutions" in this case have the same numeric values as do "x-intercepts."
If x = -4 is a "solution" of this quadratic equation, then (-4, 0) is the corresponding x-intercept. Likewise, if x = 1 is a solution, then (1, 0) is the corresponding x-intercept.
