Answer:

\frac{59}{8}  or 7\frac{3}{8}

Step-by-step explanation:

\frac{80}{4}  - 12\frac{5}{8}

First you need to make the 12 5/8 into an improper fraction by multiplying 12 by 8 and then adding the total by 5.

12\frac{5}{8} -> \frac{101}{8}

Now you have \frac{80}{4} - \frac{101}{8} so you need a common denominator by multiplying the first fraction by 2

\frac{80}{4} -> \frac{160}{8}

Then you subtract 160 - 101 which equals 59.

\frac{59}{8}  or 7\frac{3}{8}

Li believes that the graph shows a direct variation. Why is Li incorrect in saying that the graph shows a direct variation?
padilas [110]

Answer:

Option 2) When the x-value is 0, the y-value is 1.

Step-by-step explanation:

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

In a proportional relationship the constant of proportionality k is equal to the slope m of the line <em>and the line passes through the origin </em>

Remember that in a direct variation

For x=0, the value of y is equal to zero too

therefore

The graph is not a direct variation , because

When the x-value is 0, the y-value is 1.
