F(x) = 2x - 6
y = 2x - 6
2x - 6 = y |add 6 to both sides
2x = y + 6 |divide both sides by 2
x = 1/2y + 3
f^{-1}(x) = 1/2x + 3
f^{-1}(2) = 1/2 · 2 + 3 = 1 + 3 = 4
Answer: b. 4
Step-by-step explanation:
- 0.5
- 0.9
- divides very well
Use the quadratic formula where a = -16, b = 175 and c = 500 to find t. See picture for quadratic formula.
The numbers should be 2, 2, 5, 9 and 12.
<h3>What is mean, mode and median?</h3>
The arithmetic mean is found by adding the numbers and dividing the sum by the number of numbers in the list.
The median is the middle value in a list ordered from smallest to largest. The mode is the most frequently occurring value on the list.
Let us take numbers 2, 2, 5, 9 and 12.
mean = 30/5
mean= 6
range = 10.
