Answer:

Step-by-step explanation:

We will first look at the end behavior of the graph

Is it down then up which means that the degree is 3 and the coeficcent is positive

this leaves B or C

We then know that the x intercepts are (-2,0) (1,0) (3,0)

The easiest way to proceed from here is just plugging in numbers into our euqation and if the end result is 0 then we got it!

looking at the B we have

-2³-2*-2²-5(-2)+6

this equals 0 which means this is our answer (this elimates C because the only difference between the two equations is the sign on the 5x)

You can also factor it and find the zeroes that way, but it's just more work

What is -7+(-2)? I got nine but I'm not sure if that's correct.

horrorfan [7]

It's actually (-9)... think of it as a hot air balloon, the positivies being balloons and the negatives being sandbags or weights.
You have 7 sandbags/weights and add 9 more sandbags/weights, causing u to go lower, therefore, *negative* 9
Hope that helped! :))

(From Textbook) A company makes dog food out of chicken and grain. Chicken has 10 grams of protein and 5 grams of fat per ounce,

Doss [256]

Answer:

The company use 0 ounces of chicken and 100 ounces of grain in each bag of dog food in order to minimize cost.

Step-by-step explanation:

Let x be the number of ounces of chicken

let y be the number of ounces of grains

We are given that Chicken has 10 grams of protein and 5 grams of fat per ounce.

Chicken has protein in 1 ounce = 10

Chicken has protein in x ounces = 10x

Chicken has fat in 1 ounce = 5

Chicken has fat in x ounces = 5x

We are also given that grain has 2 grams of protein and 2 grams of fat per ounce

Grain has protein in 1 ounce = 2

Grain has protein in y ounces = 2y

Grain has fat in 1 ounce = 2

Grain has fat in y ounces =2y

Now we are given that . A bag of dog food must contain at least 200 grams of protein and at least 150 grams of fat.

So, equation becomes:

$10x+2y\geq 200$ ---A

$5x+2y\geq 150$ ---B

Since x and y represent the ounces .

So, $x\geq 0$ ---C and $y\geq 0$ ----D

Plot A ,B ,C and D on the graph

Refer the attached graph so , the corner points are (0,100),(10,50) and (30,0)

We are also given that chicken costs 10 cents per ounce and grain costs 1 cent per ounce

So, Cost function becomes : $c=10x+y$

At(0,100)

$c=10x+y$

$c=10(0)+100$

$c=100$

At(10,50)

$c=10x+y$

$c=10(10)+50$

$c=150$

At(30,0)

$c=10x+y$

$c=10(30)+0$

$c=300$

Minimum cost is 100 cents at (0,100)

So, the company use 0 ounces of chicken and 100 ounces of grain in each bag of dog food in order to minimize cost.

The regular price of an item at a store is p dollars. The items is on sale for 10% off the regular price. Some of the expression

Stolb23 [73]

Answer:

<u><em>C, </em></u> Expression B and Expression D

Step-by-step explanation:

<h2><u><em>Step 1 : Analyzing the question:</em></u></h2>

The regular price of an item at a store is p dollars. The items is

on sale for 10% off the regular price. Some of the expressions

below represent the sale price, in dollars, of the item.

It says " <em>item on sale for 10% off </em>". That means $p-0.1p$ or $0.9p$ .

<h2><u><em>Step 2 : Looking at the next portion of the question:</em></u></h2>

Expression A: 0.1p

Expression B: 0.9p

Expression C: 1 - 0.1p

Expression D: p - 0.1p

Expression E: p - 0.0p

<u>Expression A</u> doesn't make any sense. It only shows the how

much you save

<h3><em><u>Expression B:</u></em> This is one of the answer. </h3><h3 /><h3> $p-0.1p=0.9p$ </h3><h3 />

<u>Expression C: </u> You can't subtract $0.1p$ from $1$

<h3><em><u>Expression D: </u></em> D makes sense. $p-0.1p=0.9p$ </h3><h3 />

<u>Expression E: </u> This is the same thing as $p$

<h2><u><em>Step 3: The answers:</em></u></h2>

<u><em>The answer is C .</em></u>
