Answer:
Step-by-step explanation:
The slope is 2 and the point (0,8) is on the graph. This means we have to plug this equation to y-y1=m(x-x1) where m is the slope. We know the slope and the we have the points (0,8) so we can completely fill in this equation. y-8=2(x-0) is equal to y-8=2x. You want to isolate y so you have to add 8 to both sides. y=2x+8. The graph y=2x+8 will look like this.

Answer:
1/6
Step-by-step explanation:
It'd be slightly easier to do this computation if we were to write it as follows:
20,000 7 1
------------ * ------------- * ------
1 15,000 56
20,000/15000 reduces to 20/15, or 4/3, and 7/56 reduces to 1/8.
4 1
Thus, we have ------ * -------
3 8
which in turn reduces to 1/6.
Yes because if you simplify 24 and 4 weeks(28 days) by 2 than you would get 12 and 2 weeks(14 days)
Answer:
2
Step-by-step explanation:
6x3 = 18
4x3 = 12
18 - 12 = 6
16 / 4 = 4
6 - 4 = 2
Answer:
step by step as shown
Step-by-step explanation:
f(x) = x²-1
f(5) = 5² - 1 = 24
f⁻¹(x)
y = x²-1
x = y² - 1 swap x and y
y² = x+1 ... x+1 ≥ 0 x≥-1
y = √x+1
f⁻¹(x) = √x+1
f⁻¹(8) =√8+1 = √9 = 3
