Question

A credit card company charges $\backslash (10$when a payment is late, and $\backslash )5$a day each day the payment remains unpaid.

Is the equation $y=10+5x-3x^2$linear? Why or why not?

Short answer

The equation $y=10+5x-3x^2$is not linear. the linear equation doesn't contain a squared independent variable $x^2$.

Step-by-step solution

Step 1:Given Information

Given that a credit card company charges $\$10$ when a payment is late, and $\$5$a day each day the payment remains unpaid.

Step 2:Explanation

The general linear equation is shown down:

$y=a+bx.......\left(1\right)$

Here, $a$is the $y$-intercept and $b$is the slope. Also, $y$is the dependent variable and$x$is the independent variable.
