Where's the rest of the question?
Answer:
x = 10
Step-by-step explanation:
plug and chug using a calculator
4(10+2)
10+2= 12 x 4=48
Answer:
x = 4/3
Step-by-step explanation:
- you need to move -8x to the right side.
- 0=6x-8
- then, you need to move -8 to the left side.
- 8=6x
- you can get answer!
- x = 4/3
The answer is <span>1) ± √x+81
</span>
Step 1: Substitute y for f(x). <span>
Step 2: </span>Since every (x, y) has its partner (y, x)y switch x and y.
Step 3: <span>Solve for y.
Step 1.
The function is: f(x) = x</span>² - 81
Substitute y for f(x): y = x² - 81
Step 2.
Switch x and y: x = y² - 81
Step 3.
Solve for y (which is now f⁻¹(x)): f⁻¹(x) = y
x = y² - 81
y² = x + 81
y = +-√(x+81)
Therefore, the choice 1) is correct.
