180=2x+y
180-y=2x
(180-y)/2=x
The domain is the value of x, the range is the value of y.
A parabola opens infinitely to the right and left, so x can be any number, the domain is all real numbers
Vertically, however, a parabola opens only one way, either upward or downward. when it opens upward from a a certain level, say, the lower point (the vertex) has a y coordinate of 2, we say the range is all real numbers larger than or equal to 2, or y≥2. When it opens downward, we say the range is all real numbers smaller or equal to 2, y≤2
Answer:
C. -2 and -1
Step-by-step explanation:
-1.5 is bigger than -2 but smaller than -1.
Thus, it is between these two number
Answer:
what is this
Step-by-step explanation:
Answer:
x = 13.5°
Step-by-step explanation:
Angles 2 + 3 = a straight line, so 180°
180 - 66 = 114 = angle 2
114 = 10x - 21
114 + 21 = 10x
135 = 10x
135 / 10 = x
13.5 = x
