The line thru (-3,0) and (-6,5) has this slope:

5-0 5
m = ----------- = ------- = - 5/3
-6-(-3) -3

The y-intercept of the desired line is simply (0,0), and so b = 0 and the equation of this line is

y = (-5/3)x

What is the difference? ( -4x + 3) - (7x -<img src="https://tex.z-dn.net/?f=3x%5E%7B2%7D" id="TexFormula1" title="3x^{2}

trapecia [35]

The answer is 3x^2-19x+1

(-4x+3)-(7x-3x^2-1)
-12x+7x+3x^2+1

Combine like terms:
3x^2+(-12x+-7x)+1
= 3x^2+-19x+1

What are the real and imaginary parts of z ? z = 32 + 41.9i

goblinko [34]

Answer:

The real part is 32, while the imaginary part is 41.9

Step-by-step explanation:

z is a complex number. A complex number is made up of real and imaginary parts.

The real part is the number that stands alone, while the imaginary part is the number that is directly beside the i.

i is actually equal to $\sqrt{-1}$ . There is no solution for that.

Therefore, for the given expression, the real part is 32, while the imaginary part is 41.9.

Note: the imaginary part does not contain i.
