Sin0= y/r
X= -4 and r= 9 (radius is also the hypotenuse)
In quadrant II y is positive
X^2 +y^2 = r^2
-4^2 + y^2 = 9^2
16 + y^2 = 81
Y^2 = 81-16
Y^2 = 65
Y= sqrt65
Sin0= sqrt65/9
3x+5=2x-10
-2x -2x
X+5=-10
-5 -5
X=-15
3(-15)+y=5
-45+y=5
+45 +45
y=50
2(-15)-y=10
-30-y=10
+30 +30
-y=40
Divide by -1 on both sides
y=-40
Answer:
Yes
Step-by-step explanation:
A function is when there is no two of the same domain.
The Domain is the first coordinate which is x.

6 2/3 ÷ 2/3
= 20/3 ÷ 2/3
= 20/3 × 3/2
= 20/2
= 10

Answer:C
Step-by-step explanation:
A=4.66666 repeated
B=.4444 repeated
C=.54 repeated
I believe they are checking the biggest decimal. If you take each first number and divide by the second number, you get he decimal, the largest being .54, C.
