Answer: 21/5 or 4 1/5

Step-by-step explanation:

To solve 7/9 x 5 2/5

First Convert the improper fraction to proper fraction

5 2/5 = 27/5

= 7/9 × 27/5

Divide 27 by 9 = 3

= 7/1 x 3/5

Next, multiply the two numerators: 7 x 3 =21

And the two denominators: 1 x 5= 5

= 21/5

Collins middle school's basketball team won 75% of their games if they lost the board games how many games did they win?
attashe74 [19]

<em>The phrase in the original question is:</em>

<em>....if they lost 12 games......</em>

<em>not</em>

<em>....if they lost board games......</em>

Answer:

36 games won

Step-by-step explanation:

Given

\%Win = 75\%

Lost = 12\ games

Required

Number of games won

Give that: \%Win = 75\%

The percentage loss is:

\%Loss = 100\% - \%Win

So, we have:

\%Loss = 100\% - 75\%

\%Loss = 25\%

Calculate the number of games (n) using:

Lost  = \%Loss * n

12 = 25\% * n

Make n the subject

n = \frac{12}{25\%}

n = 48

So, the games won is:

Win = n - Lost

Win = 48 - 12

Win = 36

Identify the parent function that can be used to graph the function f(x)= -2x+2
iris [78.8K]

Answer: OPTION C

Step-by-step explanation:

2. The parent function of a linear function is the simplest form of a linear function and this is:

f(x)=x.  Because from this function we can make transformations that allow us to obtain the function f(x) = -2x + 2

3. If you take the parent function and make f(x)-1, then you have:

f(x)-1=x-1 (The function is shifted down 1 unit on the y-axis).

4. Then you make -2f(x), as following:

y=-2(f(x)-1)=-2x+2 (The function is reflected in the y-axis).

5. That is how you obtain the final function.
