Answer:
D) infinitely many solutions
Step-by-step explanation:
5 ( x-3 ) - 3x = 8x - 15 - 6x
5x - 3x - 15 = 8x - 6x - 15
2x - 15 = 2x - 15
2x = 2x
Since, equations of both lines are same. Therefore, there are infinitely many solutions.
Answer: She would need 32
Step-by-step explanation:
Answer:





The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:
Yes, the points are in a curved pattern.
Step-by-step explanation:
The correct formula for the residuals is given by:

Who represent the observed value minus the predicted. We can find the individual residuals and we got:





The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:
Yes, the points are in a curved pattern.
Answer:
m = 4 or m = -8
Step-by-step explanation:
length between 2 points = √(difference of x)² + (difference of y)²
AB² = (m - (-2))² + (5 - 3)² = (m + 2)² + 4 = m² + 4m +8
AC² = ((-1) - (-2))² + (0 - 3)² = 10
AB² = 4AC²
m² + 4m +8 = 40
m² + 4m - 32 = 0
(m - 4) (m + 8) = 0
m = 4 or m = -8
