Answer:

Step-by-step explanation:

 3x -  y  = -1

<u>-3x + 3y = 27  </u>

       2 y = 26

When adding, 3x + (-3x) = 0

3y - y = 2y

27- 1 = 26

One of the tables shows a proportional relationship.
beks73 [17]

Answer:

See attached

Step-by-step explanation:

The graph of a <u>proportional linear relationship</u> is a line that <u>passes through the origin</u> (0, 0).

From inspection of the given tables, the <u>linear equations</u> for each table of points is:

  • Table 1:  y = x + 1
  • Table 2:  y = x/2
  • Table 3:  y = x + 2
  • Table 4:  y = 2x + 1

The only equation for which y = 0 when x = 0 is y = x/2  →  Table 2.

Given points from Table 2:

  • (2, 1)
  • (4, 2)
  • (6, 3)
  • (8, 4)

To <u>graph the line</u>, plot the given points and draw a line through them (see attached).

Madelyn just graduated from college and owes $15,100 on her student loans. The bank charges a monthly interest rate of 0.2%. If
Dimas [21]

Answer:

  $121

Step-by-step explanation:

A suitable calculator or spreadsheet can tell you the payment amount for the given loan values. The annual interest rate will be 12 times the monthly, rate, or 2.4%. The number of monthly payments in 12 years is 12×12 = 144.

__

A calculator shows the monthly payment will be about $121.

__

If you want to figure this "by hand," the amortization formula is used.

  A = Pr/(1 -(1+r)^-t)

where P is the loan amount, r is the monthly interest rate, and t is the number of months.

  A = 15100(0.002)/(1 -(1.002^-144)) ≈ 120.789 ≈ 121

The monthly payment would be $121.

Mr. Menendez ran 13.1 miles at a constant rate for 150 minutes. To find how fast he ran, you solve the equation 13.1 = x • 150.
Novay_Z [31]
X represents his unit rate which is answer #1, speed in miles per minute. It wouldn't make sense to have total distance which is #2 because his total distance is what you are using to find out what x is! Then the number of miles he has run so far makes no sense whatsoever so eliminate that, then 4 is basically is the time it takes to run 13.1 miles which is 150. Hope you understand why the answer is 1. and mark as brainliest!
