Solve x + 3y = 9 3x – 3y = -13 (1 point)

zavuch27 [327]

Answer:

(-1, 10/3)

x = -1

y = 10/3

Step-by-step explanation:

To solve a system, one of the methods you can use is elimination. To use elimination, you need a variable to have the same coefficient in BOTH equations. Since both equations have "3y", with the same coefficient (3), we can use this method.

We want to eliminate a variable by cancelling it out. Since positive 3y PLUS negative 3y is 0, the variable in eliminated. ADD each of the terms in the equations together.

. x + 3y = 9

+ 3x – 3y = -13

. 4x – 0y = -4 3y - 3y = 0

. 4x = -4 Divide both sides by 4 to isolate 'x'

. x = -1 Solved for the x-coordinate

Since we know one variable, 'x', we can easily find the other, 'y'. Substitute 'x' with -1 in any of the equations. Then, isolate 'x'.

x + 3y = 9

(-1) + 3y = 9

-1 + 1 + 3y = 9 + 1 Add 1 to both sides to cancel out left side.

3y = 9 + 1 Add on the right side (9 + 1 = 10)

3y = 10 Divide both sides by 3 to isolate 'y'

y = 10/3 Solved for the y-coordinate

Put the 'x' and 'y' coordinates together in an ordered pair, which you write as (x, y).

The solution to the system is (-1, 10/3).

D. 0689271

E. 7042351

Step-by-step explanation:

If the number is 0,1 or 2, it is a win.

Otherwise, it is a loss.

Each number is a match.

A. 8531905

Two wins(0,1), 5 losses(8,5,3,9,5)

B. 4963184

One win(1), 6 losses(4,9,6,3,8,4)

C. 7269108

Three wins(2,1,0) and four losses (7,6,9,8)

D. 0689271

Three wins (0,2,1) and four losses (6,8,9,7)

E. 7042351

Three wins (0,2,1), four losses (7,4,3,5)

Find the midpoint of the line segment joining the points (9,2) and (-3,-2)

FromTheMoon [43]

Answer:

(3,0)

Step-by-step explanation:

The midpoint formula is as follows:

$( (x1+x2) /2, (y1 + y2) /2 )$

x1 would be 9, x2 would be -3, y1 would be 2, y2 would be -2. When plugged in, you should get 6/2, and 0/2 for y. When simplified, x would be 3 and y would be 0. This means that the midpoint of the line segment is (3,0)
