Factor the polynomial completely 9x^3 + 30x^2 - 25x

Mathematics
1 answer:
Rama09 [41]3 years ago
7 0
9x^3 + 30x^2 - 25x

step one: find the greatest common factor (GFC)
GFC=x

step two: factor out the GFC (write the GFC first. then in parentheses, divide each term by the GFC)

x(9x^3 over x + 30x^2 over x + -25x over x)

step three: simplify each term in parentheses

x(9x^2+30x-25) ...should be the answer

What function equation is represented by the graph?
kupik [55]

the answer would be ...

f(x) = -5/2x + 4

We know this because the constant in this equation, 4, is the y-intercept!

This means that the number without the variable is <u>where the line intersects the y-axis. </u>

Additionally, the slope is called the "rise over run", but in this case it is negative. At the point, 4, on the y-axis,<u> we go down 5 units (the numerator of the slope) and to the right by 2 units (the denominator). </u>

We find ourselves at where the line intercepts the x-axis!

I hope my explanation isn't confusing and that it is helpful! If you have any questions or concerns, message me! :)

I watched a video and didn't get my free answer, can I have some help,
vazorg [7]

Answer:

y + 13 = 5(x + 2)

Step-by-step explanation:

The slope-intercept form of the equation of a line is

y = mx + b,

where m = slope, and b = y-intercept.

From the slope-intercept equation y = 5x - 3, we see that the slope of the line is 3.

The point-slope form of the equation of a line is:

y - y1 = m(x - x1)

where m = slope, and (x1, y1) is a point on the line.

We have point (-2, -13), so x1 = -2, and y1 = -13.

We also have slope 5, so m = 5.

Now we use the coordinates of the given point and the slope in the point-slope equation.

y - (-13) = 5(x - (-2))

We simplify to get

y + 13 = 5(x + 2)
