Okay, so let's start with the labeling first:
(-4 = x1, 3 = y1) and (5 = x2, -6 = y2)
So now it's time to use the formula:
x Midpoint = (x1 + x2) / 2
y Midpoint = (y1 + y2) / 2
So then that would be:
x Midpoint = (-4 - 5) = (4 + 5) / 2 = 4.5
y Midpoint = (3 - -6) = (3 + 6) / 2 = 4.5
So therefore our answer for the midpoint would be:
(4.5, 4.5) which is D
Line AH and line BG are parallel
Answer:
Discounted price = $495 Discount Rate = 34% Solution: Let x = Original Price x = 495 + 0.35x ;Multiply whole equation by 100 to remove decimals. 100x = 49500 + 35x ;Transpose 35x to the left side of the equation. 100x-35x = 49500 ; Subtract the x terms. 65x = 49500 ; Divide both sides by 65. x = 761.54 So the original price is $761.54.
The slope for that graph is two
