Move 3x to the other side of the equal sign. You are then left with y=-3x+10.

Just make the equation look like this y = mx + b
So 3x + y =10 would equal y = -3x + 10

Trig: Which complex number's graph is shown?

Andrei [34K]

ANSWER

$2 \sqrt{2} ( \cos( \frac{7\pi}{4} + i \sin( \frac{7\pi}{4} ) )$

EXPLANATION

The complex number shown has coordinates (2,-2)

$z = 2 - 2i$

The modulus is

$|z| = \sqrt{ {2}^{2} + {( - 2)}^{2} }$

$|z| = \sqrt{ 8} = 2 \sqrt{2}$

The argument is

$\theta= \tan^{ - 1} ( \frac{ - 2}{2} )$

$\theta= \tan^{ - 1} ( -1) = \frac{7\pi}{4}$

The polar form is

$2 \sqrt{2} ( \cos( \frac{7\pi}{4} + i \sin( \frac{7\pi}{4} ) )$

The first option is correct.

Kevin bought 4 pizzas to share with friends. If each person has 2/3 of a pizza how many friends can have pizza?

rjkz [21]

Divide 4 pizzas by 2/3:

When you divide using a fraction, reverse the second fraction and multiply:

4 / 2/3 = 4 x 3/2 = 12/2 = 6 people.
