The inverse of this function is f(x) = 2x - 12.
You can find the inverse of any function by switching the f(x) and x values in the equation. Then you can solve for the new f(x) value. The result is your inverse function. The work for this one is below.
f(x) = 1/2x + 6 ----> switch f(x) and x
x = 1/2f(x) + 6 ----> subtract 6
x - 6 = 1/2f(x) ----> multiply by 2
2x - 12 = f(x) ----> change the order for consistency.
f(x) = 2x - 12
The total amount of cookies that were made was 48.
If they give half of the cookies (48 cookies total) to the class, the give half of what is left (24 is left), and they eat 12, the the answer is 48 cookies total.
Answer:
18, 23
Step-by-step explanation:
a. We know that W = 5 and D = 3 so:
P = 3W + D = 3 * 5 + 3 = 18 points
b. We know that P = 50 and D = 14 and that we are solving for W so we get:
50 = 3W + 14
36 = 3W
W = 12 which means the losses are 35 - 12 = 23.
The blue dot is at -11.3 on the number line.
