Answer: 45z + 11
Explanation:
-9(-5z - 2) - 7
= 45z + 18 - 7
= 45z + 11
have a plan and using some good tools like anki ,or xmind to make your study more effective.
Digging -28 would take 16 hours because 14 times 2 equals 28 and 8 times 2 equals 16 so answer is 16
Answer:
The coordinates of point B are (6,7).
Step-by-step explanation:
Given points are
Blue = A(-4,8)
Purple = M(1,7.5)
Green = B
It is given that point M is the midpoint of point A and B.
Let coordinates of points are (a,b).
Midpoint of two points is


Coordinates of midpoint are (1,7.5).

On comparing both sides we get


Therefore, the coordinates of point B are (6,7).
