Answer:
Step-by-step explanation:
Use the midpoint formula to solve:
We know the midpoint and one set of coordinates, so filling those in:
Since the -7 is the x coordinate of the midpoint, we set the x part of the equation equal to -7 and solve for x, and then do the same for y. The 2 equations are:
and 
We solve each one of these to get the x and y coordinates of the other endpoint. In both cases, multiply both sides of the equations by 2 and then solve by either adding or subtracting.
-14 = x - 19 so
5 = x
16 = y + 30 so
-14 = y
The coordinates of the other endpoint are (5, -14)
Answer:
The brother received 25% and the sister received 75%
Step-by-step explanation:
Answer:
1: A) 12 meters
2: B) 225 = (12 + x)(14 + x)
Step-by-step explanation:
42 times 2 = 84
84/12 = 7
(To check) 12 - 7 = 5
I'll be expecting that brainliest :)
Answer:
- 61x - 67
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
d = - 9x - 2 - (- 5x + 3)
= - 9x - 2 + 5x - 3
= - 4x - 5 and a₁ = - 5x + 3, thus
= - 5x + 3 + 14(- 4x - 5) = - 5x + 3 - 56x - 70 = - 61x - 67
