Answer:
(6, -2)
Step-by-step explanation:
The midpoint of the segment RS is point M (5, 3). Therefore, the average of the x coordinates of R and S is 5, and the average of the y coordinates of R and S is 3. The x coordinate of R is 4. For 4 and the x coordinate of S to have an average of 5, the x coordinate of S must be 6. Therefore, our point is of the form (6, y). For 8 and the y coordinate of S to have an average of 3, the y coordinate of S must be -2. Therefore, our answer is (6, -2)

ummmmmmmm u could use photo math helps alot?
t = time
Multiply the acceleration by time and add to the height:
The equation becomes H(t) = -16 * t^2 + 90
set h(t) to 0
0 = -16*t^ +90
Subtract 90 from both sides:
-90 = -16*t^2
divide both sides by -16:
t^2 = -90 / -16
t^2 = 5.625
t = √5.625
t = 2.37 seconds, round to 2.4 seconds.
Answer:
Step-by-step explanation:
12x+7<-11 and 5x-8 is greater than or equal to 40
To solve
12x+7<-11
Collect like terms
12x=-11-7
12x=-18
Divide through by 12
-18/12
=--3/2 or -1 1/2
5x-8 greater than 40
5x=40+8
5x=48
Divide through by 5
=48/5
9 3/5
