X + 3y = -3 solve for Y (ex. y= 3 + 5x

AnnyKZ [126]

Answer:

y = -1/3x - 1

Step-by-step explanation:

Let's solve for y.

Step 1: Add -x to both sides.

x+3y+−x=−3+−x

3y=−x−3

Step 2: Divide both sides by 3.

y=-1/3x-1

$\frac{-1}{3} x-1$

Sin^22x - 2cos2x + 2=0

zhuklara [117]

Answer:

x=πn, n∈Z

Step-by-step explanation:

if sin²2x=1-cos²2x, then

1-cos²2x-2cos2x+2=0; ⇒ cos²2x+2cos2x-3=0; ⇔ (cos2x+3)(cos2x-1)=0;

$\left[\begin{array}{cc}cos2x+3=0\\cos2x-1=0\\\end{array} \ \ \left[\begin{array}{cc}x \ 'does-not-exist'\\cos2x=1\\\end{array} \ \ 2x=2\pi n, n=Z \ x=\pi n, n=Z$

Yakvenalex [24]

Answer:

How much should I spend on rent and utilities?

We calculate your monthly rent at 25% of your monthly net income (after monthly debt). This allows you to have enough cash left for other expenses and savings. Utilities are in general 2.5% of your monthly net income, and so in this case, you should expect to spend $0 or more per month on utilities.
