Question

I got this question that says to Complete the table for the given rule. and that is y=5x and it says (the chart has only numbers under y so you have to find what number x is)

What number is x for 4 and 2
X Y
0 5
0 4
0 2

Answer 1

x=0.8 if y=4, x=0.4 if y=2

Explanation:

Rearrange the equation to get:

5x= 4 and

5x= 2

Divide equations by 5 to get:

x=0.8

x=0.4

Answer 2

X Y

1 5

4/5 4

2/5 2

Explanation:

y=5x

We we know y we need to solve for x

X Y

5

4

2

Let y =5

5 = 5x

Divide by 5

5/5 =5x/5

1=x

Let y =4

4 = 5x

Divide by 5

4/5 =5x/5

4/5=x

Let y =2

2 = 5x

Divide by 5

2/5 =5x/5

2/5=x

X Y

1 5

4/5 4

2/5 2
