Answer:

x² - x - 2

Step-by-step explanation:

Since the curve cuts the x-axis at x = -1 and 2. The factors will be x+1 and x-2

Taking the product of the factors

f(x) = (x+1)(x-2)

f(x) = x² - 2x + x - 2

f(x) = x² - x - 2

Hence the required function is x² - x - 2

In 2005, joe planted a tree that was 3 feet tall. In 2010, the tree was 13 feet tall. Assuming the growth of the tree is linear,
kifflom [539]
<h2>Greetings!</h2>

Answer:

2 feet per year

Step-by-step explanation:

First, we need to find the amount it grew:

13 - 3 = 10

So between 2005 and 2010 it grew 10 feet.

Now to find the yearly growth we need to divide the distance by time:

10 ÷ 5 = 2

So it grew 2 feet per year.

James is running on a trail that is 5/4 of a mile long. So far he has run 2/3 of the trail. How many miles has he run so far?
aalyn [17]
Step 1) You would need to convert your 2 fractions into equivalent numbers. In this case, the closet gcf (greatest common factor) is 12. So, 5/4 would convert to 15/12 and  2/3 converts to 8/12.

Step 2) You know have your decimals that are equivalent. All you have left now is to subtract. Take 15/12 and subtract 8/12 from it. You would now get 7/12 of a mile that is still needed to run. 

Step 3) Usually, you would simplify your new fraction. In this case, our fraction doesn't simplify. It will stay 7/12 of a mile. For example, If our number had ended up being 4/12, then we would simplify it to 1/3 of a mile. Because, 4 divided by 4 is 1 and 12 divided by 4 is 3. You can't simplify your answer anymore.

Tameka bought 50 cans of soda (cola, grape, and orange) to serve at a party. She has 8 more colas than grape sodas, and 3 less o
Alexxx [7]

<u>Answer: </u>

Number of three types of soda’s can bought by Tameka that is grapes, colas and oranges are 15, 23 and 12 respectively.

<u> Solution: </u>

Total numbers of sodas cans bought by Tameka = 50

Three types of cans are colas, grape and orange.

Let’s assume number of grape cans = x

Given that Tameka has 8 more colas can than grapes.

So number of colas can = 8 + number of grapes can = 8 + x

Also orange cans are 3 less than grape cans.

So number of orange cans = number of grape cans – 3 = x – 3

Total number of cans = number of grape cans + number of colas cans + number of orange cans  

= (x) + ( 8 +x ) + ( x – 3) = 3x +5

And Total number of cans is 50 , it means

3x + 5 = 50

On solving above equation of one variable, we get

3x = 50 – 5 = 45  

x = 15

Number of grapes can = x = 15

Number of colas can = 8 + x = 8 + 15 = 23

Number of orange cans = x – 3 = 15 – 3 = 12

Hence number of three types of soda’s can bought by Tameka that is grapes , colas and oranges are 15 , 23 and 12 respectively.
