Answer:
That is the system.
y = x - 4
y = 4x - 10
If you are looking for the solution then use the method of substitution or the method of elimination.
The first car consumed 21 gallons while the second car consumed 49 gallons. here is the how it's done.
for the first car gallons consumed is 15/50x70= 21 gallons
the second car consumed 35/50x70=49 gallons

This condition must be observed for the case of a quadratic equation with equal roots:




Answer:
the length is 9 in. and the width is 7 in.
Step-by-step explanation:
this is hard to explain but i promise that this is the correct answer.
Answer to first part 1: First you obtain number of intervals you would like to have by getting the square root of the total number of observations. In this case, square root of 14 = 3.74; round up and use 4.0.
Answer to Second part: 2: The interval width is then obtained by dividing the range by the number of intervals. For this case, interval width = (42-9)/4 = 8.25. This can be rounded up to the convenient evenfigure of 10.0.
Hope this helps!!!!
