Answer:

A x =30

Step-by-step explanation:

(y+x) and (y-x) make a straight line so they add to 180 degrees

(y+x) + (y-x) = 180

Combine like terms

y+y+x-x=180

2y=180

Divide by 2

2y/2 = 180/2

y= 90

(y+x) and 2x make a straight line so they add to 180 degrees

y+x+2x = 180

Combine like terms

y+3x = 180

Since we know y we can substitute it in

90+3x = 180

Subtract 90 from each side

90-90+3x= 180-90

3x = 90

Divide by 3

3x/3 = 90/3

x= 30

Slope -4 passing through the point (5,3).

bonufazy [111]

A negative slope means the line would be going downward, so you would go down first (instead of up as with a positive slope), then over right.

Therefore, you would go down 4 (or negative 4 considering you are going down) and right 1.

Rise over run still applies here. Rise over run is a fancy way of saying to put the number (or slope) in fraction form.

-4 as a fraction would be -4/1.

So start at (5,3), go down 4 and over 1, repeatedly and you got it.

**Just remember the rise over run can be confusing with negative slopes.**

Solve 2cos ²y -siny -1=0 for 0° ≤y≤360°
