Answer:
x = negative 9 or x=-9
Step-by-step explanation:
4x+24=2x+6. We can subtract 6 from both sides to get
4x+18=2x. After that, we can switch the sides to get
2x-18=4x, so negative 18 (-18) is equivalent to 2x. We get
2x=-18, divide both sides by 2 to get x=(-9).
Answer:
12/13
Step-by-step explanation:
Use SOH-CAH-TOA.
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
sin B = opposite / hypotenuse
The side opposite of angle B is side b. The hypotenuse is c.
sin B = b / c
sin B = 12 / 13
Answer:
[-3, -1)
Step-by-step explanation:
Just took the quiz and got it right
