Answer:
4x - 12
Step-by-step explanation:
Expand 8 - 4(-x + 5) as follows:
8 + 4x - 20
4x - 12 (First answer is the correct one)
Perpendicular means that the slopes are negartive inverses, aka
slope1 times slope2=-1
y=mx+b
slope=m
y=-1/2x-2
slope=-1/2
we need to find negative inverse
-1/2 times what=-1
answer is 2
y=2x+b
input the point (2,-2) to find b
(x,y)
(2,-2)
-2=2(2)+b
-2=4+b
minus 4 from both sides
-6=b
y=2x-6
the equtaion is y=2x-6
The first 2 represents 200,000
The second 2 represents 20,000
The third 2 represents 2,000
The fourth 2 represents 200
The fifth 2 represents 20
The last 2 represents 2
Answer:
Step-by-step explanation:
So for question 1, we can see that we have a 30 60 90 triangle with a hypotenuse of 9.
So therefore, y=9/2 and x=4.5sqrt3.
