Answer:
x = 5 , y = 5
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values.
sin30° =
, cos30° =
, then
sin30°=
=
=
( cross- multiply )
2x = 10 ( divide both sides by 2 )
x = 5
and
cos30° =
=
=
( cross- multiply )
2y = 10
( divide both sides by 2 )
y = 5
Answer:
Some possible values are -5, -3, -2.
Step-by-step explanation:
Basically if d(discriminant)
d > 0 = 2 x intercepts,
d = 0 means one x intercept
d < 0 = 0 x intercepts

Answer:
x^2 + y^2 = 36
Step-by-step explanation:
Just add 36 to both sides. This is a circle with the center at the origin and radius 6.
Answer: I think the last option is the correct answer.
