2nd term:: a = -1/5 = -2/10
3rd term:: a*r = (-2/10)(2) = -4/10</span>
Answer:
Step-by-step explanation:
Take it in steps. First, find 7/9+6. Then we'll find 8+6/3, and, finally, we'll divide the two answers.
1:
7/9+6 = 7/15
2:
8+6/3 = 14/3
3:
or
Then take that in chunks: 7/14 and 15/3.
7/14 = 1/2
15/3 = 5/1
Use those to rewrite it as .
1/5 = .2
2/3 ≈ .6667 so we'll keep writing it as 2/3
.2/2 = .1, so:
=
Perpendicular lines intersect and form 4 right angles (90 degree angles)
Answer:
If lines are perpendicular, their slopes are the <u>negative reciprocals </u>

Answer:
Step-by-step explanation:
The midpoint formula is:
where (x₁, y₁) and (x₂, y₂) are the points are the endpoints.
We are given the points: (2,4) and (6,8). Therefore,
Substitute the values into the formula.
Find the x coordinate first.
- Add 2 and 6: 2+6=8
- Divide by 2: 8/2=4
Find the y-coordinate next.
- Add 4 and 8: 4+8= 12
- Divide by 2: 12/2=6
The midpoint of EF is (4,6)
