Midpoint (m) = (x₁ + x₂)/2 , (y₁ + y₂)/2
= (3 - 11)/2, (-5 + 1)/2
= -8/2 , -4/2
= -4 , -2
distance (d) = √[(x₁ - x₂)² + (y₁ - y₂)²
=√ [(-4 - (-2))² + (-2 - 4)²
= √[(-2)² + (-6)²]
= √[4 + 36]
= √40
= 2√10
Answer:
they are both going in the same dirrection but this does not mean they are parrallel or perpendicular.
Step-by-step explanation:
So just say neither
Answer:
Step-by-step explanation:
xy = 300
x + y = 50 Solve for y
y = 50 - x substitute into xy = 300
x(50 - x) = 300 Remove the brackets.
50x - x^2 = 300 Bring the left to the right.
0 = x^2 - 50x + 300
This is a quadratic. It will have 2 solutions.
a=1
b = - 50
c = 300
Put these into the quadratic equation.
It turns out that x has two values -- both plus
x1 = 42.03
x2 = 6.97
x1 + y1 = 50
42.03 + y = 50
y = 50 - 42.03
y = 7,97
(42.03 , 7.97)
====================
x2 + y2 = 50
6.97 + y2 = 50
y2 = 50 - 6.97
y2 = 43.03
(6.97 , 43.03)
