Two angles are supplementary when they <span>add up to 180 degrees.
x = </span><span>smaller angle
</span>2x+3 =<span> larger angle
x + 2x + 3 = 180
3x = 180 - 3
3x = 177
x = 177/3
x = 59</span>° ← smaller angle
2x + 3 = 2*59 + 3 = 121° ← larger angle
Answer:
(h, k) is the point that represents the vertex of this absolute value function
Step-by-step explanation:
Recall that the vertex of an absolute value function occurs when the expression within the absolute value symbol becomes "zero", because it is at this point that the results in sign differ for x-values to the left and x-values to the right of this boundary point.
Therefore, in your case, the vertex occurs at x = h, and when x = h, then you can find the y-value of the vertex by looking at what f(h) renders:
f(h) = a | h - h | + k = 0 + k = k
Then the point of the vertex is: (h, k)
Answer: To find the inverse, interchange the variables and solve for y.
Step-by-step explanation:
f-^1 (x)= - 5x/3
