Answer:
2/3
Step-by-step explanation:
There are a couple of different ways that division of fractions can be done.
1) "invert and multiply"

__
2) use the numerators when the denominators are the same

Answer:
y = -4
Step-by-step explanation:
See attached worksheet.
Answer:
(1,-2)
(0,-3)
(-3,0)
Step-by-step explanation:
each point on the line -x+y=-3
Use the Pythagorean Theorem.
a² + b² = c²
3² + b² = 19²
9 + b² = 361
b² = 352
b = 4√11
Now, solve for the remaining angles by using the trigonometric ratios:
Sine = opposite/hypotenuse
sin(A)= 3/19
sininverse(3/19) = 9.1 = angle A
180-9.1-90 = 80.9 = angle B
