Answer 1

x y

0 5

1 10

2 20

Explanation:

Given the equation: y = 5(2) .....[1]

Here, x is the input variable and y is the output variable.

For x =0

Substitute in equation [1]; we have;

y = 5(2) = 5 x 1 = 5

For x = 1

Substitute in equation [1]; we have;

y = 5(2)*1 = 5 x 2= 10

For x =2

Substitute in equation [1]; we have;

y = 5(2)*2 = 5 x 4 = 20

Therefore, the table values which is correct for the equation is;

x y

0 5

1 10

2 20
