Is -2x+4y=0 a funtion?

Yes, it is a function

Step-by-step explanation:

-2x+4y=0 is a function as it maps one x value to just one y value.

-2x+4y=0 can be rearranged to turn it into a linear equation:

-2x+4y=0

4y=2x

y=x/2

Since this equation is a line (see in attatched graph) and every x value has just one y value, it is a functuon.

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
