Where’s the answers ?
Step-by-step explanation:
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:
X= -12
Step-by-step explanation:
-2x-4=20
-2x-4+4=20+4
-2x=24
x=-12
First 5 terms are: -1,0,3,8,15
Step-by-step explanation:
we will put n=1,2,3,4,5 to find first 5 terms of the sequence
Explicit formula for sequence is:

Putting n=1

Putting n=2

Putting n=3

Putting n=4

Putting n=5

Hence,
First 5 terms are: -1,0,3,8,15
