The function f(x) = −x2 − 5x + 50 shows the relationship between the vertical distance of a diver from a pool's surface f(x), in feet, and the horizontal distance x, in feet, of a diver from the diving board. what is a zero of f(x), and what does it represent?

the answer is x=5; the diver hits the water 5 feet away horizontally from the board. i know because i had this one and got it right.

step-by-step explanation:

the answer is   x = 10; the diver hits the water 10 feet horizontally from the board

step-by-step explanation:

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
