Question

F(x)= 4x-5 what is f(100)?

Answer 1

Answer:

26.25 = x

Step-by-step explanation:

f ( x ) = 4x - 5

f  ( x ) = Y-value

x = x - value

If f ( 100 ) = The Y is 100

100 = 4x - 5

+5   =      +5                    Add 5 on both sides. The 5's will cancel on the right

-------------------

105 = 4x                 Divide by 4 on both sides. The 4's will cancel on the right

----- =  ----

4     =  4

26.25 = x

Hope this helps!!
