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.

Arisa [49]

Answer:

$78.72

Step-by-step explanation:

To find 30% of the original value, we need to turn this percentage into a decimal or a fraction and then multiply it by the original value

  • 30% is equivalent to 0.30, \frac{30}{100}, and \frac{3}{10}
  • So we can use either of these values. I will use 0.30 for simplicity

  • ($262.40)(0.30) = $78.72 is the amount saved

Answer:

no, because it has a constant rate of change

Step-by-step explanation:

this is because the x and y change at the same rate. non linear means that they dont change at the same rate.
