What is the inverse of the function f(x) = x - 12?

ludmilkaskok [199]

Answer: $\displaystyle f(x)^{-1}=x+12$

Step-by-step explanation:

First, we will rewrite the function in terms of y as in y = x - 12.

Second, we will swap the x and y values.

y = x - 12

x = y - 12

Third, we will solve for y. In other words, we will isolate the y variable and get it "by itself" on one side of the equal sign.

x = y - 12

x + 12 = y

y = x + 12

Lastly, we will change y back into terms of the function, but the inverse.

$\displaystyle f(x)^{-1}=x+12$

Jeans ($48) Sweater ($42) Tennis Shoes ($69) T-Shirt ($21) Blouse ($52) Heather is shopping for back-to-school clothes. The item

IgorC [24]

You can use rounding to figure this problem out. If the number in the ones place is 0 to 4, round down to the nearest tens place; if the number in the ones place in 5 to 9, round up to the nearest tens place.

48 rounds to 50.
42 rounds to 40.
69 rounds to 70.
21 rounds to 20.
52 rounds to 50.

Now use mental math to estimate the cost (50 + 40 + 70 + 20 + 50). Heather will spend about $230.

Answer:
D) $230

The measure of an angle is 63°.

Irina-Kira [14]

A complementary angle is an angle that adds up to 90 degree each and every time. So, therefore the correct formula to use is 90-63=27. Now, you have your answer and can check it twice if you'd like by the formula. Again your answer is 27.

What value of x is in the solution set of 2x – 3 > 11 – 5x?

pochemuha

Given:

2x -3 > 11 -5x

Simplify both sides:

2x - 3 > -5x + 11

Add 5x to both sides:

2x - 3 +5x > -5x + 11 +5

7x - 3 > 11

Add 3 to both sides:

7x - 3 +3 > 11 + 3

7x > 14

Divided 7 to both sides:

$\frac{7x}{7}$ > $\frac{14}{7}$

x > 2
