Total people=180
discount received people=25%+10%=35%
People who did not receive discount=100-35%=65%
65%of 180=65×180/100=117
So 117 people did not receive discount

Answer:
(0, 9)
Step-by-step explanation:
The midpoint coordinates are the averages of the end point coordinates.
M = (A +B)/2
M = ((8, 10) +(-8, 8))/2 = (8 -8, 10+8)/2 = (0, 18)/2
M = (0, 9)
The midpoint is (0, 9).
Step-by-step explanation:
Her brother has 85 * x stickers.
4x + 2y = 8 (1)
8x + 4y = -4y (2)
A) Two lines are parallel if they have the same gradient
- putting both equations into the gradient- intercept form ( y = mx + c where m is the gradient)
(1) 4x + 2y = 8
2y = 8 - 4x
y = -2x + 4
(2) 8x + 4y = -4y
<span> </span>8x = -4y - 4y
y =

y = -x
<span>
Thus the gradient of the two equations are different and as such the two lines are not parallel</span>
B) When two lines are perpendicular, the product of their gradient is -1

p = (-2) * (-1)
p = 2
<span> ∴
the two lines are not perpendicular either.</span>
Thus these lines are SKEWED LINES
