What is the y-intercept of the function f(x)
f(x) = -_x + ?

Note: Your function is not clear.

So, I am assuming a sample function such as

f(x) = -2x + 3

So, I would solve the question based on the assuming function. The reason is that the procedure will remain the same and your concept will be likely cleared anyways.

Please check the explanation.

Step-by-step explanation:

Assuming the function

f(x) = -2x + 3

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

now substituting x = 0 in the function

y = -2x + 3

y = -2(0) + 3

y = 0 + 3

y = 3

Therefore, the point (0, 3) represents the y-intercept of the function.

The graph of the function y = -2x + 3 is also attched below.

From the graph, it is clear that

at x = 0, y = 3

Thus, point (0, 3) represents the y-intercept of the function.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

answer: c
