Use the elimination method to solve the system of equations. Choose the correct ordered pair.

x + y = 9
x – y = 7

# Choice
A. (12, –3)
B. (8, 1)
C. (7, 0)
D. (16, –7)

Step-by-step explanation:

x + y = 9 equation 1

x - y = 7 equation 2

Now solving both equations

x + y = 9

x - y = 7

2x = 16

Therefore x = 8

Now putting x = 8 in equation 1

8 + y = 9

Therefore y = 1

Here B (8 , 1) is your answer

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4
