Slope: (y2-y10/(x2-x1)
(-4-4)/(-1-3)= -8/-4=2
Yes it does x is the same thing as one
Answer:
<em>24 minutes</em>
<em></em>
Step-by-step explanation:
Given:
Distance per lap = 2 miles
Speed of Lou Lambert = 160 miles/hr
Speed of Ralph Redding = 170 miles/hr
Speed difference between the two = 170 - 160 = 10 miles/hr
Therefore, we can say that <em>Ralph gains 10 miles in 60 minutes </em>over Lou<em>.</em>
We have to find the time in which Ralph will gain 2 laps i.e. 2 2 = 4 miles.
Let us use unitary method to find the required time.
10 miles are gained by Ralph in 60 minutes
1 mile will be gained in
4 miles will be gained in 6 4 = <em>24 minutes</em>
What about the spaces, we can't answer if we know what those spaces are for
Answer:
-4
Step-by-step explanation:
1x+3+4=-1-4x-12
1x+7=-13-4x
5x=-20
x=-4
You can isolate to get x=-4, but that is not one of the options.
