Given the function [tex]f(x) = 4x - 51 + 3[/tex], for what values of [tex]x[/tex] is [tex]f(x) = 15[/tex]?

A. [tex]x = 2, x = 8[/tex]
B. [tex]x = 1.5, x = 8[/tex]
C. [tex]x = 2, x = 7.5[/tex]
D. [tex]x = 0.5, x = 7.5[/tex]

Answer :

Final answer:

To find the values of x for which f(x) = 15, set the function equal to 15 and solve for x. The answer is x = 15.75.


Explanation:

Answer:

To find the values of x for which f(x) = 15, we need to set the function equal to 15 and solve for x:

4x - 51 + 3 = 15

Combine like terms:

4x - 48 = 15

Add 48 to both sides:

4x = 63

Divide both sides by 4:

x = 15.75

Therefore, the answer is x = 15.75.
