Answer:
The other endpoit has this cordinadetes (11, 11).
Step-by-step explanation:
Midpoint (MD) (Xm, Ym)
Xm = 5
Ym = 2
Xm of the Midpoint: Xm = X1 + X2/ 2
Ym of the Midpoint: Ym = Y1 + Y2/2
<em>We can say that S is (x1, y1), so x1 = -1 and y1 = -7</em>
Then:
Xm = -1 + x2/2
5= -1 + x2/2
10 = -1 + x2
x2 = 11
Also:
Ym = -7 + y2/2
2 = -7 + y2/2
4 = -7 + y2
11 = y2
Answer:
Plan A would be the least expensive
Step-by-step explanation:
Plan A= $0.45x100= 45, 45+40=$85
Plan B= $0.35x100= 35, 35+70= %105

The lower-priced speaker docks and higher-priced speaker docks is 9 and 36 respectively.
<h3>Algebra</h3>
- Cost of higher-priced speaker = $170
- Cost of lower-priced speaker = $80
- Number of lower-priced speaker = 4x
- Number of higher-priced speaker = x
Higher-priced speaker = 170 × x
= 170x
Lower-priced speaker = 80 × 4x
= 320x
Total sales = $4,410
170x + 320x = 4,410
490x = 4,410
divide both sides by 490
x = 4,410 / 490
x = 9
So,
Number of lower-priced speaker = 4x
= 4 × 9
= 36
Number of higher-priced speaker = x
= 9
Therefore, the lower-priced speaker docks and higher-priced speaker docks is 9 and 36 respectively.
