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: the x-intercept would be (2,-2)
Answer: (a) IV (b) positive (c) (d) C (e)
<u>Step-by-step explanation:</u>
a) - = , which is located in Quadrant IV <em>per the Unit Circle. </em>
b) sec is . Cos is the x-coordinate. The x-coordinate inQuadrant IV is positive.
c) the reference angle is the angle from to 2π =
d) since the angle is below the x-axis and the reference angle is, then the angle is equal to )
e) sec = ⇒ sec = = = =

Answer: (a) (b) (0, -1) (c) A (d) -1
a) - = - =
b) is on the Unit Circle at (0, -1)
c) sin = which equals on the Unit Circle.
d) sin is the y-coordinate. sin = -1
