Children = .65 * people
people = 520 / .65
800 people were in attendance
Negative multiply negative = Positive
Negative multiply positive = negative
Thus the answer is -4a + 16b - 12c - 12d.
First we need to find the gradient of K
which is y1-y2/x1-x2
(-1,3) and (5,-2)
so it becomes 3-(-2)/-1-5
m=-5/6
when two lines are perpendicular their gradients multiply to make -1
that means the gradient of L has to be 6/5
we can substitute the point on L (5,-2) and the gradient of 6/5 into y=mx+c
-2 = (6/5) x 5 + c
c = -8
the equation of line L is y= 6x/5 -8
Answer:
the area of the top and bottom are 16 so the area of the left and right must be less than 16 in order to make it a true rectangle
Have two ways: 1. Reflects with respect x-axis and later with respect y-axis.
2. The opposite: first with respect y-axis and later with respect x-axis.
B and D are correct.
