Answer:
Yes, the table is proportional.
Step-by-step explanation:
To find out if a table is proportional or not see if they have the same constant of proportionality.
The formula for finding the constant of proportionality is <em>k </em>= <em>y/x.</em>
1/4 ÷ 1 = 1/4
1/2 ÷ 2 = 1/4
3/4 ÷ 3 = 1/4
1 ÷ 4 = 1/4
They all have the same constant of proportionality which means they are proportional.
Answer:
x = 8
Step-by-step explanation:
Her mistake was subtracting 2 on both sides. Instead she should've added 2 on both sides.Getting a result of 2x=16. Then you divide 2 on both sides to get x = 8.
