Answer: the point is already plotted. Which equation do you want to plot?
Step-by-step explanation:
If you mean negative thirteen, the number on the right of it would be negative twelve (-12)
Answer:
y = -0.25x + 40 ; $26,000
Step-by-step explanation:
From the graph attached ;
The regression equation, y could be obtained :
y = mx + c
m = slope = Rise / Run = (y2 - y1) / (x2 - x1)
Slope = (15 - 40) / (100 - 0)
Slope = - 25 / 100
Slope = - 0.25
c = intercept, where the regression line crosses the y-axis, from. The graph, c = 40
The regression equation goes thus :
y = -0.25x + 40 ; y = price of car ; x = number of miles driven
Price of car that has been driven for 56000 miles
y = - 0.25(56) + 40
y = - 14 + 40
y = 26
Hence, price of car is $26,000
Answer:
651 - ( -13 ) = 664
Step-by-step explanation:
As we know when there is a minus sign we hv to change the sign of the number after it .....
Therefore... ( -13 ) will become ( + 13 )
Then we can solve the equation...
651 - ( -13 ) = 651 + 13 = 664
Hope this helps....

Answer:
x = 13
Step-by-step explanation:
a right angle is 90 degrees and so you have to make both sides of that line add up to 90. so youre gonna want to add both sets of the numbers and equal it to 90 (90 = 53 + 24 + x) you can subtract 53 and 24 from both sides and youll be left with 13.
