Answer:
C
Step-by-step explanation:
The best way to solve this is to transfer -217 to the other side. So add 217 to both sides
0 ≤ 7 + 217 - 28v Combine
0 ≤ 224 - 28v Now add 28v to both sides
28v ≤ 224 Divide by 28
28v/28≤224/28
v ≤ 8
You should have 2 questions on your mind.
- Why go to all the trouble of putting things on the opposite sides?
- What is the answer
1. You so all that trouble so that you don't have to switch the < to >. As long as you have the letter and its coefficient > 0, then you are going to be right.
2. The is v is less than or equal to 8. That's C
Answer:
A motorcycle will complete the 540 mile trip in 
And the car will complete it 2.25 hours less, i.e 11.25 -2,25 = 9 hours.
then,
Speed of the car is 
60t + 48t = 540
108t = 540
Divide both sides by 108 we get
t = 5
So, they will meet in 5 hours,
After 5 hours, the motorcycle will have traveled 
and the car will have traveled = 
Answer:
-430

Answer:
Undefined
Step-by-step explanation:
The formula for slope is 
So use the x's and y's from the given points to solve for the slope
(10, -6) (10, -6)
The slope for this line would be undefined because a number cannot be divided by 0
