How would i solve these?
olchik [2.2K]
So for a, the y-intercept would be positive 2 (first equation) and the slope would be 3/1. When you graph the y-intercept, which you have to do first, you can use the slope to figure out the line. The same thing would happen with the second equation. -8 is the y-intercept and -2/1 is the slope. (Negative slope would be, in this case, down 2 right 1)

You are running a concession stand at a basketball game. You are selling hot
Nuetrik [128]

x= hot dogs

y= soda

Total sold

1 x + 1 y = 87 .............1

2 x 0.50 y = 78.50 .............2

Eliminate y

multiply (1)by -0.50

Multiply (2) by 1.00

-0.50 x -0.50 y = -43.50

2 x + 0.50 y = 78.50

Add the two equations

1 x = 35.00

/ 1

x = 35.00

plug value of x in (1)

1 x + 1 y = 87

35 + y = 87

y = 87 -35

y = 52

y = 52.00

x= 35 hot dogs

y= 52 soda
