How many solutions does the system have? y=4x-8 4y=4x-8

There is one solution (x=2, y=0)

Step-by-step explanation:

y=4x-8

4y=4x-8

Divide the second equation by 4

y = x - 2

Set the two equations equal

4x - 8 = x-2

Subtract x from each side

3x -8 = -2

Add 8 to each side

3x = 6

Divide by 3

x = 2

Now find y

y = x-2

y = 2-2=0

x=2,y=0

Step-by-step explanation:

4(4x-8)=4x-8

16x-4x=32-8

12x=24

X=2

Y=0

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

the equation is y=5x

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
