Which point is an x-intercept of the quadratic function f(x)=(x-8)(x+9)?

The x-intercept points are (8,0) and (-9,0)

Step-by-step explanation:

In order to determine the x-intercept points of a quadratic function, we have to know the procedure.

If we want to determine the y-intercept point, we have to replace the "x" value by zero.

If we want to determine the x-intercept point, we have to replace the "y" value (also called f(x) ) by zero. Sometimes there is not x-intercept point.

I have attached an image of a quadratic function graph where it shows differents x-intercept points.

In this case,

There are two "x" values to get the equality:

Finally, the x-intercept points are (8,0) and (-9,0)

the dimensions are:

step-by-step explanation:

we want to find the dimensions of a rectangular box with volume of

we factor to obtain;

we rewrite the rightmost factor to obtain;

recall that:

we apply difference of two squares formula to obtain;

hence the dimensions are

$75.00

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
