If (a, b) is on the graph of f(x), then the point (b, a) must be on the graph of the inverse function f^-1(x).
<h3>Therefore your answer is d. (-2, 8).</h3>
Answer:
x=1
Step-by-step explanation:
Answer:
∠x = 72°
Step-by-step explanation:
since two sides are equal, their opposite angles are equal.
Then the upper angle is also equal to 54°.
All triangle angles add up to 180°.
∠x = 180 - 54 - 54 = 72°
Answer: a = 18
Step-by-step explanation:
The pythagorean theorem says that the sum of the square of the two legs of a triangle is equal to the square of the hypotenuse.
The two legs are 80 and a, and the hypotenuse is 82 which gives us
80² + a² = 82²
a² = 324
a = 18.
C is correct. here is the graph to prove it. the black line is the only one that goes through all 4 dots.
