Answer:
D = 20H
Step-by-step explanation:
The amount Troy (D, in dollars) charges to mow a lawn is proportional to the time (H, in hours) it takes him to mow the lawn.
Hence, we can write D = kH ......... (1), where k is a constant.
Now, given that Troy charges $30 to mow a lawn that took him 1.5 hours to mow.
So, from equation (1) we get
30 = 1.5k
⇒ k = 20.
Therefore, equation (1) becomes D = 20H (Answer)
1440 mi/do
The other three are stating a mileage per time period , this one does not
Let's solve the inequality.
x - 5 >= -2
Add 5 to both sides:
x >= 3
The solution of the inequality is the number 3 and all numbers greater than 3.
Since the inequality symbol is "greater than or equal to" which includes "equal to", draw a solid dot on 3. Because of the "greater than" part, you need numbers greater than 3, so color to the right of 3.
The correct answer is choice B.
