Hi there!
Since the slope of a line perpendicular to a line is always the negative inverse of that slope, you just switch the numerator and denominator around and add or omit the negative sign to the original slope.
The answer would be -2.
Hope this helps!
Answer:
Verizon Wireless offers better plan
Step-by-step explanation:
Now it is easiest to calculate an yearly cost for both companies.
First calculate cost for Verizon
If y is annual payment and x is monthly payment
Relation is
y = 20 + 12x
y = 20 + (12)(20)
y = 260
So for Verizon wireless, annual amount is $260
Now calculate cost for Consolidated Communication
If y is annual payment and x is monthly payment
Relation is
y = 10 + 25x
y = 10 + (12)(25)
y = 310
So for Consolidated Communication, annual amount is $310.
Here by comparison we can see that the offer of Verizon Wireless is better in long term.

Answer:
see explanation
Step-by-step explanation:
Given that S varies inversely as G then the equation relating them is
S = 
← k is the constant of variation
To find k use the condition S = 7 when G = 1.8, then
k = SG = 7 × 1.8 = 12.6
S = 
← equation of variation
When G = 3, then
S = 
= 4.2
