Answer:
Step-by-step explanation:
Let
y --->Mala's age
x---> sister's age
we know that
---> equation A
so
The sum of ages of the sisters is
substitute equation A in the expression of the sum of ages
simplify
refer to the image given below:
Answer:
Step-by-step explanation:
Midpoint = (x₁+ x₂)/2 , (y₁ +y₂)/2
= [(-1)+(-3))/2] , (-2 + 9)/2
= (-4/2) , (-7/2)
= (-2 , -3.5)
Answer:AAS
C would be the answer
Step-by-step explanation:
Answer:
5x + 6y = -10
Step-by-step explanation:
(-2, 0) and (-8, 5)
m = (y₂ - y₁) / (x₂ - x₁)
m = (5 - 0) / (-8 -(-2)
m = 5 / (-8+2)
m = -5/6
y = mx + b
(-8, 5)
5 = -5/6(-8) + b
5 = 40/6 + b
b = 5 - 40/6
b = -5/3
y = mx + b
y = -5/6x - 5/3 *6
6y = -5x -5(2)
6y = -5x - 10
5x + 6y = -10
