Answer:
B.
Step-by-step explanation:
The Domain is {-8, - 3, 1 , 4} and it is not a function because the value 1 maps on to 2 and -5. A one-to-many relation is not a function.
Answer:
x=41
y=139
Step-by-step explanation:
x+y = 180 since they form a straight line
y is 3x +16
y = 3x +16
Replace y in the first equation
x+3x +16 = 180
Combine like terms
4x +16 = 180
Subtract 16 from each side
4x+16-16 =180-16
4x =164
Divide each side by 4
4x/4 =164/4
x = 41
y = 3x +16
y = 3*41 +16 = 123+16 =139
Answer:
3x[2] + 5x +2

Answer:
x = 90° or π/2 rad
Step-by-step explanation:
4+ 2 sin x=14-8 sin x
2 sin x + 8 sin x = 14 - 4
10 sin x = 10
sin x = 1
Using a calculator
x = sin
1
x = 90° or π/2 rad
