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
Answer:
B and D
Step-by-step explanation:
B= 4(3n-2)
D=12n-8 which equals 4(3n-2)

Answer:
x=5
Step-by-step explanation:
Isolate the x by adding 9 on both sides:
Take the square root of both sides:
Simplify:
<u>x=5</u>
Answer:
6,000,000.005
Step-by-step explanation:
The correct answer in [standard form] is 6,500,000
one million= 1,000,000
six million= 6,000,000
one thousandth= .001
five thousandth= .005
6,000,000.005
Word Form: Six million and five thousandth
