Which of the following best describes the equation below? y = 4x + 3 a. nonlinear b. both linear and nonlinear c. neither linear nor nonlinear d. linear

D

Step-by-step explanation:

its linear because you can make it into a line:

a complex number is a number that can be expressed in the form a + bi, where a and b are real numbers, and i is a solution of the equation x2 = −1. because no real number satisfies this equation, i is called an imaginary number. has no real solution, since the square of a real number cannot be negative.

no

step-by-step explanation:

2-7=-5

7-2=5

when you combing like terms for ech expression, 5 and -5. these numbers are not equal to each other.
