Answer:
- 6 m/s
Step-by-step explanation:
The rate of change is a measure of the slope and can be calculated using the slope formula
m = 
with (x₁, y₁ ) = (2, 78) and (x₂, y₂ ) = (10, 30) ← 2 points on the line
m = 
= 
= - 6
Rate of change is - 6 m/s
Which problem do u need help on
The equation of a line is Y=mx+b
You know that the slope is -2 and the slope is 'm' so sub it into the equation.
Y=-2x+b
To have an equation of a line you need the 'b' or 'y' intercept and the slope.
This means you have to find the 'b' because you already know the slope which is -2. To find the 'b' you have to sub in the coordinates and then solve for 'b'
Y=-2x+b
(x,y)
(3,0)
0=-2(3)+b
0=-6+b
6=b
Therefore the equation of the line is Y=-2x+6 <span />
72, because 360/4 courses = 90 as an average for Adrianna. This means that 360/5 courses equals 72 for roberto.
Answer:
Sammy can make 9 bows.
Step-by-step explanation:
3 feet of Ribbon
1/3 for each bow
1/3 + 1/3 +1/3 = 3/3 or 1 so she can make 3 bows out of one foot of ribbon
so if you repeat this than you should get 9 bows out of three feet of ribbion.
