First refrigerator cost
C(x1)=700+85x
C(10)= 700+850
C(10)= 1550
refrigerator 2nd
C(x2) = 1000+25x
C10) =1000+250
C(10)=1250
Now you know it.
same cost
700+85x=1000+25x
60x=300
x= 5 years
Answer: The y values remain the same, but the x value changes its sign
Step-by-step explanation: There is a way to remember this. If you reflect across the y axis the y will stay the same and, if you reflect across the x axis the x will stay the same. So if the axis is in the problem then that axis will stay the same and the other axis will change to its opposite.
D) because a straight line has an infinite solution
Answer:
A) on the y-axis
Step-by-step explanation:
A residual plot has the Residual Values on the vertical axis (y-axis); the horizontal axis (x-axis) displays the independent variable.
