Match the polynomial on the left with the appriately factored expression on the right x^2-3x-18
Lapatulllka [165]

The factored expression of the polynomial expression given as: x^2 - 3x - 18 is (x + 3)(x - 6)

<h3>How to match the polynomial?</h3>

The polynomial expression is given as:

x^2 - 3x - 18

Express -3x as 3x - 6x

So, we have:

x^2 + 3x - 6x - 18

Factorize the polynomial expression

x(x + 3) - 6(x + 3)

Factor out x + 3

(x + 3)(x - 6)

Hence, the factored expression of the polynomial expression given as: x^2 - 3x - 18 is (x + 3)(x - 6)

You need to buy some chicken for dinner tonight. You found an ad showing that the store across town has it on sale for $3.19 a p
SSSSS [86.1K]

Answer:

Yes, it is worth the extra drive, going to the further store is cheaper.

The cheaper option saves you $0.89.


Step-by-step explanation:

1.) Neighborhood store

It is 2.4 miles away

The car averages about 25 miles per gallon, then you would need:

2.4 miles / (25 miles/gallon) = 0.096 gallons of gas < 13 gallons (Ok)

The gas is about $3.89/gallon, then the gas would cost:

0.096 gallons * ($3.89/gallon) = $0.37344 = $0.37

The chicken is sold for $3.49 a pound, and you need 6 pounds, then you would pay:

6 pounds * ($3.49/pound) = $20.94

In total you would need:

$0.37 (gas) + $20.94 (chiken) = $21.31 if you buy the chicken in the neiborhood store

2.) Store acroos town

It is 8.2 miles away

The car averages about 25 miles per gallon, then you would need:

8.2 miles / (25 miles/gallon) = 0.328 gallons of gas < 13 gallons (Ok)

The gas is about $3.89/gallon, then the gas would cost:

0.328 gallons * ($3.89/gallon) = $1.27592 = $1.28

The chicken is sold for $3.19 a pound, and you need 6 pounds, then you would pay:

6 pounds * ($3.19/pound) = $19.14

In total you would need:

$1.28 (gas) + $19.14 (chiken) = $20.42 if you buy the chicken in the store across town


$20.42 < $21.31, then it is worth the extra drive, going to the further store is cheaper.

The cheaper option saves you: $21.31-$20.42=$0.89

2. Graph each equation using a table of values.<br> (a)) y = 3x - 1
kiruha [24]

Make an x and y table, and pick any values to plug in for x in the equation.

I will use the numbers from -2 to 2

Now plug in the values you picked for x into the equation to find its y-value

x = -2

y = 3x - 1   Plug in -2 for x

y = 3(-2) - 1

y = -6 - 1

y = -7

x = -1

y = 3x - 1

y = 3(-1) - 1

y = -3 - 1

y = -4                

Do the same for the rest of the numbers, and graph each point and draw a line connecting them.

You are getting ready for a family vacation. you decide to download as many movies as possible before leaving for the road trip.
PilotLPTM [1.2K]
Here is the solution for the given problem above.
Given: 1 2/5 hour = time it takes to download a movie
            5 1/4 hours = total hours for the download
            ? = number of movies downloaded
First, we need to simplify 1 and 2/5 hour, which is 1.4 hour, and 5 1/4 is 5.25 hours. Next, to get the number of movies downloaded, we divide 5.25 by 1.4 and the result is 3.75. Round this off to a whole number and we  get 4. Approximately, you were able to download 4 MOVIES. Hope this helps.
