Answer:
c=rt is the equation to express the total cost c to use the internet at the coffeehouse for t hours.
Step-by-step explanation:
Given A coffeehouse charges a flat rate, r for each hour customer wants to use the internet. we have to write the equation to express the total cost c to use the internet at the coffeehouse for t hours.
Charges of internet per hour = r
Total hour = t hours
Hence, Cost = (Charges per hour)(Total hours)
=
∴ c=rt
which is the linear equation to express the total cost c to use the internet at the coffeehouse for t hours.
Answer:
True, since 1 is 1/1, which is 100%

Step-by-step explanation:
Answer: C. Package 3
First, find out what each cell phone package costs for 1 month by dividing the cost by however many months:
Package 1: $160 ÷ 4 = $40 for 1 month
Package 2: $128 ÷ 4 = $32 for 1 month
Package 3: $60 ÷ 2 = $30 for 1 month
Since package 3 costs the least amount of money for 1 month out of all of the other packages, that package offers the best deal. So C) Package 3 is your answer
(x1,y1) = (-2,7)
m = -5
(x,y) = (a,2)
Forming the equation,
(y-y1) = m(x-x1)
y - 7 = -5[x - (-2)]
y - 7 = -5x - 10
y + 5x = -3
Putting the values of (x,y) we get,
2 + 5a = -3
5a = -5
a = -1
