Answer:

  (-2, 5), (-2, -19), (5.2, 2.6)

Step-by-step explanation:

You can add ±12 to either the x- or the y-coordinate, as was done in the first two answers above.

Or, you can figure the side lengths of a triangle with hypotenuse 12 and add those to the coordinates. For example, a 3-4-5 right triangle multiplied by 2.4 will have side lengths of 7.2, 9.6 and a hypotenuse of 12. Hence we can find one of your end points to be ...

  (-2+7.2, -7+9.6) = (5.2, 2.6)

diamong [38]

Answer:

m+n=54 and m=3n+8 is the system of equations that could be used to determine the price of each book.

Step-by-step explanation:

Given,

Total cost of maths book and novel = $54

Let,

Cost of maths book = m

Cost of novel = n

According to given statement;

m+n=54      Eqn 1

the price of the math textbook, m, is $8 more than 3 times the price of the novel

m = 3n+8     Eqn 2

m+n=54 and m=3n+8 is the system of equations that could be used to determine the price of each book.

Help! I’ll give BRAINLIEST!
iren [92.7K]

It’s letter C.

If you start at point (0,0) and go up two over one (rise over run) to the left, you’ll be at (-1,2). Go up two over one again to the left to get to (-2,4). Your equation would be: y=-2x+0 (0 because you started at 0 so your y-intercept is 0) though since it’s +0 you can leave that out and have y=-2x. It’s a negative slope because the line would be going down to the right.

Find an ordered pair that is a solution to the equation.<br><br> 3x - y = 8
mojhsa [17]

Answer:

Step-by-step explanation:

There are so many order pairs that can solve this equation.

To solve this problem, we choose any value of x and find y;

  Given expression;

            3x  - y  = 8

 if x  = 0,

           3(0) - y  = 8

                 -y  = 8

                 y = -8;

  (0,-8) is a solution

ii.

  if x  = 1,

          3(1) - y = 8

               - y = 8 - 3

                  y = -5

        (1, -5) is a solution
