Answer:
Please check the explanation.
Step-by-step explanation:
The midpoint (a, b) of line joining points (x₁, y₁) and (x₂, y₂)
a = x₁ + x₂ / 2
b = y₁ + y₂ / 2
Given that the midpoint of AB is (4, -3).
i.e. (a, b) = (4, -3)
Given that A has coordinate (1, 5).
i.e. (x₁, y₁) = (1, 5)
We have to determine the coordinates of B.
i.e. (x₂, y₂) = B
Thus,
4 = (1 + x₂)/2
(1 + x₂) = 4 × 2
1 + x₂ = 8
x₂ = 7
and
-3 = (5 + y₂)/2
(5 + y₂) = -3 × 2
5 + y₂ = -6
y₂ = -11
so (x₂, y₂) = (7, -3) = B
Thus, the coordinates of B = (x₂, y₂) = (7, -3)
Therefore,
x₂ + y₂ = 7 + (-3)
= 7 - 3
= 4
Hence, the value of x₂ + y₂ = 4
Answer:

Please represent the angle with a Greek letter, such as Ф, α, β, etc. Click on the 'omega' symbol at the bottom of your screen, to display math symbols.
8π 180 deg
------ * -------------- = 160° This is the formula for
9 π conversion of radians to degrees
17, because you divide 22 in half and add 6 because there are half as many mollies and there are 6 more guppies then goldfish.
Answer:
No, this matrix is singular
Step-by-step explanation:
-1*-2*3=6
2*1*-2=-4
1*2*-1=-2
So, 6+(-4)+(-2)=0 -SINGULAR-
