Answer:

First point: (1,0)

Second Point: (2,1)

Third Point: (3,2)

Fourth Point: (8,7)

Step-by-step explanation:

For the first two points, you have to plot the two pairs of coordinates that are given. After this, you have to plug the x values into the equation to get the missing y values.

For example: The third point

X= 3

Y= X - 1

Y= 3 - 1

Y=2

So this means that the third coordinate is (3,2)

Two Cars Start at the Same Point and travel in the Same Direction at the average speeds of 70 miles per hour, and 40 miles per h

cestrela7 [59]

Answer:

You can check it by solving it in your head. They are separating at the rate of 55-40 or 15 miles per hour. So in 1 hour or 60 minutes they'll be 15 miles apart, so in 20 minutes they'll be 5 miles apart, so in 40 minutes they'll be 10 miles apart. So it has to be 40 minutes.

Step-by-step explanation:

55t-40t=10

15t=10

15t/15=10/15

2/3

40 Minutes

Yvette is considering taking out a loan with a principal of $16,200 from one of two banks. Bank F charges an interest rate of 5.

umka21 [38]

Hi there
First find the monthly payment of each offer to see which monthly payment is lower
The formula of the present value of annuity ordinary is
Pv=pmt [(1-(1+r/k)^(-kn))÷(r/k)]
Pv present value
PMT monthly payment
R interest rate
K compounded monthly 12
N time
Solve the formula for PMT
PMT=pv÷[(1-(1+r/k)^(-kn))÷(r/k)]

Bank F
PMT=16,200÷((1−(1+0.057÷12)^(
−12×8))÷(0.057÷12))
=210.53

Bank G
PMT=16,200÷((1−(1+0.062÷12)^(
−12×7))÷(0.062÷12))
=238.21

From the above the monthly payment of bank f is lower than the bank g
And since the lifetime of bank g is lower than bank f the answer is
b. Yvette should choose Bank F’s loan if she cares more about lower monthly payments, and she should choose Bank G’s loan if she cares more about the lowest lifetime cost.

Good luck!
