Answer:
C. 3.2
If GF = 3.2 a possible measure of TS is 3.2
Scale for the horizontal axis is in increments of 1. Scale for the vertical axis in in increments of 100. Black – Lesha, Blue - Keon Part B:What does the rate of change for each line represent? The rate of change represents the amount of calories per snack.Part C:What is Lesha’s rate of change? Answers will vary.Example: 100 calories/snack. Part D:How does Lesha’s rate of change compare to Keon’s rate of change? Why are the two rates different from one another? In this case it doubles - the rates are different because with healthy snacks the <span>caloric intake per snack is less than unhealthy snacks.</span>
Answer:
1 song costs $1.21
Step-by-step explanation:
The distance between the number of songs for 16 and 18 is 2, and the same from 18 to 20. So with this we can find the difference between the costs correlated with these amounts of songs and divide by 2 to get the cost per song.
21.78 - 19.36 = 2.42
24.20 - 21.78 = 2.42
2.42 / 2 = 1.21
This means for every 1 song bought, you pay $1.21
To solve this, set up a proportion with X being our unknown. If she cleans 12 houses in 10 hours, she cleans 27 houses in X hours. It will look like
.
Now cross-multiply to get 12x = 27(10) or 12x = 270. Divide by 12 on both sides to isolate x, X = 22.5.
It will take Kathy 22.5 hours to clean 27 houses. Must be some pretty small houses.
Slope intercept form is y = mx + b where m is the slope and b is the y intercept.
6 = -3 (2) + b
6 = -6 + b
b = 0 (there is no b)
So your equation would be:
y = -3x
