If f (x) = 4x + Ax+6X - 5 and f (2) = 1, what is the value of A?

-7

Step-by-step explanation:

First, set the equation equal to one and the x's to 2

Then, solve the parts without variables

4 (2) + a (2) + 6 (2) - 5=1

8+a (2) + 6 (2) - 5=1

8+a (2) + 12-5=1

Then add like terms

8+a (2) + 7=1

15+a (2) = 1

Then subtract 15 from both sides

a (2) = -14

Finally, divide by two on both sides

a=-7
