Equation 2 is the only linear one due to the fact that there is no exponent on the x or y values.

Answer:

Equation 2: y = 8x

Step-by-step explanation:

A linear function or equation is one in which the variables involved have no exponents other than 1.

the options are:

Equation 1: y = 2x^2 + 1

Equation 2: y = 8x

Equation 3: y = 5x^3 - 1

Equation 4: y^2 = 4x - 1

Equation 1 has a quadratic exponent, the same for Equation 4.

And Equation 3 has a cubic exponent.

So the only equation that is linear is the Equation 2, because there are no exponents other than 1 in the expression.

Unit test<br> 4% of a number is what fraction of that number?
AlexFokin [52]

Answer:

1/25

Step-by-step explanation:

Well, in order to figure this out, we need to figure out how many times 4 goes into 100, because it is 4 out of 100%.

So if you divide 100 by 4 you get 25, which means 4 goes into 100 25 times.

So the fraction would be 1/25 of the number.

Hope this helps :)
