Any function in the form

is known as an
exponential function. And one of the important things to know about such functions is that the

is the value of the function when

. Check it out:

Recall that
any number to the zero power is 1, so this becomes:

So, again, when

we see that

. (Don't forget that

is the same thing as

!) This represents the point

, which is also the y-intercept of the function!
Answer:
Step-by-step explanation:
Angle A:
Because quadrilateral ABCD is cyclic, angles A and C are supplementary. This means angle A = 180 - 101 = 79 degrees
Angle B: same kind of logic as A
2/5x -3 = -y
-2/5x + 3 = y
