In the equation y = 6.7x, what is the constant of proportionality

The constant in an equation would be the number multiplied to x,

In the equation y - 6.7x, the constant would be 6.7

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.

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.
