Part (a):
Turn percentage into a decimal.
26.8% = 0.268
Multiply.
67.5 * 0.268 = 18.09 (Answer)
Part (b):
Divide.
89.87 / 215 = 0.418
Turn into a whole number.
0.418 = 41.8 (Answer)
Turn percentage to a decimal to check.
215% = 2.15
Multiply
41.8 * 2.15 = 89.87

step 1
Find out the slope WX
W(2,-3) and X(-4,9)
m=(9+3)/(-4-2)
m=12/-6
m=-2
step 2
Find out the slope YZ
Y(5,y) and Z(-1,1)
m=(1-y)/(-1-5)
m=(1-y)/-6
m=(y-1)/6
step 3
Remember that
If two lines are perpendicular
then
their slopes are negative reciprocal
that means
(y-1)/6=1/2 -----> because the negative reciprocal of -2 is 1/2
solve for y
2y-2=6
2y=6+2
2y=8
<h2>y=4</h2>
Answer:
4x-y=-9
Step-by-step explanation:
Answer: D
Step-by-step explanation:
y= -4x
y = mx + b
m = -4
If you start on (0, 0), you'd go down 4 and to the right one, so then you'd have another point at (1, -4).
