W(x)=x^3 - 5x^2 + 8x - 4 I need the x and y intercepts and the behavior of this equation.

1 answer:

4 0

X intercept is where the line crosses the x axis or where y=0
y intercept is where the line crosses the y axis or where x=0

the equation is 3rd degree and the leading coefient is positive so it goes from bottom left to top right, with 2 changes in direction (up to down or down to up)

x intercepts
W(x)=0=x^3-5x^2+8x-4
um, I graphed it and the x intercepts are at x=1 and x=2

y intercept is where x=0
W(0)=0^3-5(0)+8(0)-4=-4
the y intercept is y=-4

Below are two parallel lines with a third line intersecting them.

Ulleksa [173]

Answer:

x = 88

Step-by-step explanation:

These angles are same side exterior angles, and when the lines are parallel, same side exterior angles are supplementary

x + 92 =180

Subtract 92 from each side

x+92-92=180-92

x =88

liq [111]

Answer:

8,185,320 different leadership structures

Step-by-step explanation:

Since the order at which the members of the committee are chosen matters, this is a permutation of 4 out 55 people and it is given by:

$n=\frac{55!}{(55-4)!}=55*54*53*52 \\\\n=8,185,320$

8,185,320 different leadership structures are possible.

How do you interpret a slope and the y- intercept?

nexus9112 [7]

The slope is rise over run, how many times you go up (or if down it'd be a negative) and over.
The y-intercept is what point on the y axis the line passes through
