Answer:
2) y = 0.95x + 4
3) slope: height increases by 0.95 units as x increases by 1 unit
intercept: initial height
Step-by-step explanation:
Using (20,23) and (40,42)
Slope: (42 - 23)/(40 - 20)
0.95
y = 0.95x+ c
23 = 0.95(20) + c
c = 4
y = 0.95x + 4
Answer: y=8x-3
explanation:
y=mx+b
m= slope
b= y intercept
m=8 b=-3
y=8x-3
Answer:
120 votes
Step-by-step explanation:
So one way to solve this is by creating an equation to solve for x.
So we are given 4/7, that will be one side of the equation.
And we are trying to figure out how many votes out of the 210 she received, so on the other side of the equation we will have x/210, since we are solving for x.
So 4/7 = x/210
We want to get x alone, so we can multiply 4/7 by 210, which equals 120.
So x equals 120!
Answer:
18
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is
here [ a, b ] = [ 1, 5 ]
f(b) = f(5) = 3 × 5² = 75
f(a) = f(1) = 3 × 1² = 3, hence
average rate of change = = = 18
