Answer:
A: 60%
Step-by-step explanation:
- multiply .6 by 4.5 and then you get 2.7
- then add 2.7 and 4.5 and then you get 7.2
Write the conjugates of them then FOIL both the top and bottom, then factor
Sorry for the awful art skills but I'm pretty sure that is the answer
You would take 280-105=175 miles away and take 105 and divide that by your time 1.5 too get 70 mph
Answer: They are not parallel, they are coincident
Step-by-step explanation:
If two lines have the same slope but a different y-intercept, the lines are parallel. If two lines have the same slope and the same y-intercept, the lines are coincident.
We can rewrite 5x−y=−5 adding -5x to both sides and multiplying by -1:
5x - y =-5
5x - y -5x = -5 - 5x (adding -5x to both sides)
-y = -5 - 5x
Multiplying by -1
y = 5x + 5
Both equations look the same so they are coincident. They have the same intercept y=5 and the same slope m=5.
