angleBOC = 270°
All 3 angles meet at O thus
angleBOC = angle AOC + angle BOD = 120° + 150° = 270°
Answer:
y = 2/3x + 6
Step-by-step explanation:
If two lines are parallel, that means their slopes are the same.
Rewrite 2x - 3y = 15 to y = 2/3x - 5
The slope is 2/3, so the answer should have a slope of 2/3 as well.
The equation is now y = 2/3x + b
To find b, substitute (-3,4)
y = 2/3x + b
4 = 2/3(-3) + b
4 = -2 + b
6 = b
So the equation is y = 2/3x + 6
That's not a linear system, but you have an awesome school system for giving you this problem.

Multiply by 6xy to clear the fractions.

That's a second degree equation, also known as a conic. That one happens to be a hyperbola.


Let's clear the fractions from the second equation, multiplying out common denominator xy:


We are being asked to find the meet of two hyperbolas, so we expect two answers, a quadratic equation.
Substituting,





We have to rule out x=0 because it's in the denominator.


Answer: (44/19, 33/20)
Y=10x+1
x=-1→y=10(-1)+1=-10+1→y=-9
x=0→y=10(0)+1=0+1→y=1
x=1→y=10(1)+1=10+1→y=11
x=5→y=10(5)+1=50+1→y=51
