Answer:
D) (8, 6)
Step-by-step explanation:
Given: M(9, 8) is the midpoint of RS . The coordinates of S are (10, 10).
Here we have to use the mid-point formula:

Here (x, y) is the midpoint.
(x, y) = M(9, 8)
(x2, y2) = (10, 10)
Here x = 9, y = 8 and x2 = 10 and y2 = 10
Now let's plug in these values in the mid-point formula and find (x1, y1)

Let's simplify and find the value of x1 and y1



So the coordinates of R(8, 6)
Answer:
m < -9
Step-by-step explanation:
m+15<6
Subtract 15 from each side
m+15-15<6-15
m < -9
Answer:
(3.5, 17)
Step-by-step explanation:
It would be nice to see the whole graph, so we can see where the functions cross.
Without that information, we can still eliminate unreasonable choices.
A) the quadratic at y=3.5 is well above the exponential
B) the most likely choice (3.5, 17)
C) at x=-8, the quadratic is above the exponential
D) neither graph goes anywhere near y = -8
Answer:
41.1
Step-by-step explanation:
It was decreased by 26.7 between noon and midnight.
If it was -14.4 at midnight, which i after noon, you minus 26.7 and -14.4.
26.7--14.4 is 41.1.
(- and - = +)
Answer: each of the students took 1/4 of an eraser home.
Step-by-step explanation:
On the last period our teacher had 1/2 of an eraser left. She gave it equally to 2 students. This means that the amount of eraser that each student takes home would be
(1/2)/2 = 1/2 × 1/2 = 1/4 of an eraser. Converting to decimal, it becomes 0.25 of an eraser.
