You would start by saying his budget is $80 so you start with 80= he pays an initial fee of $59.50 every month plus $5 per gigabyte so you would set it up like
80=59.50+5x
X being how many gigabytes he uses then you solve 80-59.50 is 20.5 divided by 5 gives you 4.1 but you round down cause you don’t want to pass the limit so therefor the most gigabytes he can use is 4
Answer:
S = 5t
Step-by-step explanation:
Speed of the pedestrian = 5 km/h
It means that distance walked in 1 hour = 5 km
Distance walked in t hours = 5*t km = S
Hence;
Formula for dependence of S on t is .
Answer:
Step-by-step explanation:
Applying double angle identity:
Doing so would give:
We need to get everything to one side so we have 0 on one side.
Subtract 1 on both sides:
Add on both sides:
Let's factor the left-hand side.
The two terms on the left-hand side have a common factor of .
.
This implies we have:
.
We need to solve both equations.
You are asking they be solved in the interval .
This means look at your unit circle and find when you have your y-coordinates is 0.
You this at 0 and . (I didn't include because you don't have a equal sign at the endpoint of .
Now let's solve
Subtract 1 on both sides:
Divide both sides by 2:
Now we are going to go and look for when the y-coordinates are -1/2.
This happens at and .
The solution set given the restrictions is
Need help myself not sure sorry
Answer:
Factoring a monomial means breaking it down into each individual prime number and/or variable factor. This is also called "expanding" a monomial.
