Write a polynomial f(x) that meets the given conditions. Answers may very
AnnZ [28]

The polynomial is: f(x)=x^3-2x^2-23x+60

Step-by-step explanation:

We need to write a polynomial f(x) that meets the given conditions: Degree 3 polynomial with zeros 3,-5,4

Since zeros are at 3,-5 and 4

So, x=3, x=-5 and x=4

or:

x-3=0, x+5=0 and x-4=0

Multiplying all factors to find the polynomial:

(x-3)(x+5)(x-4)=0\\(x(x+5)-3(x+5))(x-4)=0\\(x^2+5x-3x-15)(x-4)=0\\(x^2+2x-15)(x-4)=0\\x(x^2+2x-15)-4(x^2+2x-15)=0\\x^3+2x^2-15x-4x^2-8x+60=0\\x^3+2x^2-4x^2-15x-8x+60=0\\x^3-2x^2-23x+60=0

So, the polynomial is: f(x)=x^3-2x^2-23x+60

Ronch [10]

Based on the image attached of the graph, the points that show equivalent ratios that would also be on the graph are option A and D which are: (6,18)  (1,3).

<h3>What is the graph about?</h3>

Note that: \frac{x}{y}

=\frac{3}{9}

= 1/3

So when you use 1/3 to compare all the options given, you will see that only option A and D  is equal to the value given.

So if a person can write that  we got  1 fish and we needs 3 gallons and when a person  make a point on the line, it will be (1,3).

The other equivalent fraction is known to be 6/18. When a person multiply the numerator and denominator by 2, the value that will be obtained is:

\frac{3 x 2 }{9 x 2}   = 6/18.

So therefore, Based on the image attached of the graph, the points that show equivalent ratios that would also be on the graph are option A and D which are: (6,18)  (1,3).

See full question below

Christina wants to buy some miniature goldfish. She reads that a 9-gallon aquarium is the right size for 3 miniature goldfish. The graph represents this relationship.

A. (6,18)

B. (6,12)

C. (4,10)

D. (1,3)

25 points!
Dahasolnce [82]

Answer:

Okay, so. What I'd do is this.

(5x+3)+(x+3)=180

Then I'd combine like terms.

So:

(5x+3)+(x+3)=180\\ 6x+6=180

Once you've got 6x, you subtract 6 from 180.

(5x+3)+(x+3)=180\\ 6x+6=180\\6x=174

Now all that's left to do is divide each side by 6 to get x.

X should be 29.

Step-by-step explanation:

(5x+3)+(x+3)=180

You know that adding the equations will give you 180 because you know they're supplementary.
