Answer:
Step-by-step explanation:
<u>Given points:</u>
- A(-1, -9) and M(0.5, -2.5)
Let the coordinates of B are (x, y)
<u>Use midpoint formula to determine the point B:</u>
- 0.5 = (- 1 + x)/2 ⇒ 1 = -1 + x ⇒ x = 1 + 1 = 2
- -2.5 = (-9 + y)/2 ⇒ -5 = -9 + y ⇒ y = -5 + 9 = 4
Answer: 2
2x-7=11 X=9 set up the up the negative portion of solutions Set up the negative portion of the 2x - 7= - 11 x= -2 and then x = 9,-2
Step-by-step explanation:
Subtract 13 from both sides.
-13
-7 = -20
-2x = -20
Divide by 2 on both sides.
Remember: Negative divided by a negative makes a positive.
-2/-2 = 1
-20/-2 = 10
Your answer:
x = 10
