110+90+145=345
345 divided by 3=115

so the score of her third game was 145 points.

Answer: A.145

Step-by-step explanation:

Given : Nola bowled 3 games in her bowling league.

She had a mean score of 115.

The score of her first game was 110.

The score of her second game was 90.

Let x denotes the score of her third game.

The formula to find the mean score is given by  :-

\text{Mean score}=\dfrac{\text{Sum of scores }}{\text{Number of tests}}\\\\\Rightarrow\ 115=\dfrac{110+90+x}{3}

Multiply 3 on both the sides, we get

345=200+x

Subtract 200 from both the sides , we get

x=345-200=145

Therefore. the score of her third game = 145

Answer:

the range is {7,5,1}

Step-by-step explanation:

To find the range, just plug in the domain into the function.

f(-1) = -2(-1) + 5 = 7

f (0) = -2(0) + 5 = 5

f(2) = -2(2) + 5 = 1

What is the slope of a line that is perpendicular to a line wise equation is 5y=10+2x
PIT_PIT [208]
First solve the equation by dividing 5 on both sides...

Y = 5\2x + 2

Now we want perpendicular and the line to flip across the axis so the answer is....

Y = -2\5 + 2

If f(7)=22, then f^-1(f(7))=?<br> Please help!!
alexira [117]

Answer:

  7

Step-by-step explanation:

In general, the point of an inverse function is to show you the value that gives a particular function value. That is, ...

  f^{-1}(22)=7\\\\f^{-1}(f(x))=x\\\\f^{-1}(f(7))=7

For what values of the variables are the following expressions defined? 1. 5y+2 2. 18/y 3. 1/x+7 4. 2b/10−b Example: X&gt;7
Serga [27]

Answer:

1. All real numbers

2. All real numbers except y = 0

3. All real numbers except x = -7

4. All real numbers except b = 10

Step-by-step explanation:

For any function to be defined at a particular value, it should not be <em>approaching to a value </em>\infty<em> or it should not give us the </em>\frac{0}{0}<em> (zero by zero) form </em> when the input is given to the function.

The value of function will depend on the denominator.

Now, let us consider the given functions one by one:

1. 5y+2

Here denominator is 1. So, it can not attain a value \infty or \frac{0}{0}<em> (zero by zero) form </em>

So, for all real numbers, the function is defined.

2.\ \dfrac{18}{y}

At y = 0, the value

At\ y =0,  \dfrac{18}{y} \rightarrow \infty

So, the given function is <em>defined for all real numbers except y = 0</em>

<em></em>

<em></em>3.\ \dfrac{1}{x+7}<em></em>

Let us consider denominator:

x + 7 can be zero at a value x = -7

At\ x =-7,  \dfrac{1}{x+7} \rightarrow \infty

So, the given function is <em>defined for all real numbers except x = -7</em>

<em></em>

4.\ \dfrac{2b}{10-b}

Let us consider denominator:

10-b can be zero at a value b = 10

At\ b =10,  \dfrac{2b}{10-b} \rightarrow \infty

So, the given function is <em>defined for all real numbers except b = 10</em>

<em></em>
