Answer:
3 * (x + 7)
Step-by-step explanation:
Mark number as x
Then the sum of a number and seven is x + 7
Three times x + 7 can be written as
3 * (x + 7)
Parentheses mean that we first add x and 7 and then multiply their sum by 3
Alternatively you can write it as 3x + 21, since
3 * (x + 7) = 3 * x + 3 * 7 = 3x + 21
<h2>SOLVING</h2>
How do the graphs f(x) and f^-1(x) relate?
These two functions are inverses of each other.
That's the way these two are related to each other.
f^-1(x) is the inverse function of f(x), and f(x) is the inverse function of f^-1(x).
Answer:
Answer:
11.02-9.91= 1.11
Step-by-step explanation:
|-11.02| - |-9.91| (First solve in absolute)
11.02 - 9.91 (any values outside absolute becomes positive)
1.11

Answer:
<u>0</u>
Step-by-step explanation:
<u>Given</u>
- (2, -8) → (x₁, y₁)
- (-4, -8) → (x₂, y₂)
<u>Formula</u>
- Slope (m) = Δy/Δx = y₂ - y₁ / x₂ - x₁
<u>Solving</u>
- m = -8 + 8 / -4 - 2
- m = <u>0</u>
