Which of the following describes the zeroes of the graph of f(x) = –x^5 + 9x^4 – 18x^3?

Allushta [10]3 years ago

Answer:

second option

Step-by-step explanation:

Given

f(x) = - x^{5} + 9x^{4} - 18x³

To find the zeros let f(x) = 0, that is

- x^{5} + 9x^{4} - 18x³ = 0 ( multiply through by - 1 )

x^{5} - 9x^{4} + 18x³ = 0 ← factor out x³ from each term

x³ (x² - 9x + 18) = 0 ← in standard form

x³(x - 3)(x - 6) = 0 ← in factored form

Equate each factor to zero and solve for x

x³ = 0 ⇒ x = 0 with multiplicity 3

x - 3 = 0 ⇒ x = 3 with multiplicity 1

x - 6 = 0 ⇒ x = 6 with multiplicity 1

What is slope-intercept form of a line that passes through points (2,11) and (4,17)?​
kramer

Answer:

y = 3x + 5

Step-by-step explanation:

Okay, so first we do the equation for rise over run which is y2 - y1/ x2 - x1

so plug the numbers 11 - 17/ 4 - 2 getting the slope -3, now since we found the slope we need to find the intercept form, what you have to do now is plug in a coordinate from the x value and y value one of the pairs essentially so,

y = 3x + b, I chose your first pair

11 = 3 x 2 + b

equals to,

11 = 6 + b

now we want b, by itself.

5 = b

so the total intercept form answer is

y = 3x + 5

I will check over it,

11 = 3 x 2 + 5

11 = 11

I hope this helped!

Given h(t) = -2(t+ 5)^2 +4, find h(-8).
bekas [8.4K]

Answer:

Substitute -8 as x into the equation.

h(-8)=-2(-8+5)^2+4

h(-8)=-2(-3)^2+4

h(-8)=-2(9)+4

h(-8)=-18+4

h(-8)=-14

-2/3y-3/4=5 <br> What is the answer i need to show my work please
vodka [1.7K]

Answer:

y=  -69/8  (negative 69 over 8)

Step-by-step explanation:

First, you have to simplify both sides of the equation:

-2/3y+ -3/4 =5

Second, add 3/4 to both sides:

-2/3y +-3/4 + 3/4=5 +3/4

-2/3y= 23/4

Next, multiply both sides by 3/(-2) (3 over -2)

(3/-2)*(-2/3y)= (3/-2) * (23/4)

<em><u></u></em>

<em><u>y= -69/8</u></em>
