What function is the inverse of f(x)=x2-16

Mathematics

Vera_Pavlovna [14]3 years ago
5 0
For inverse functions, switch the position of x and y, and solve for y.
y= x^2-16
x= y^2-16
x-16 = y^2 
\sqrt{x-16} =  \sqrt{y^2}

Anna and Maya are competing in a dance tournament where dance moves are worth a certain number of points if a dance move it's do
Gre4nikov [31]

Anna's current number of points = 225 points.

She danced correctly and earned = 75 points.

And when she danced incorrectly she loses = 30 points.

Note: For dancing correctly earned points will be added and for dancing incorrectly loses points will be subtracted from the total points has in starting.

So, we can setup an expression as

Current points + earned points - loses points

Plugging values, we get

225 +75 -30   Required expression.

Adding 225 and 75, we get 300.

Therefore, 225 +75 -30 = 300-30.

Subtracting 30 from 300, we get

300-30=270.

Therefore, Anna's final score is 270 points.

15 points for someone who can answer &amp; explain this to me thanks
iris [78.8K]

Answer:

see explanation

Step-by-step explanation:

Given

\frac{9}{a^2+9a+20} , \frac{7a}{a^2+11a+28}

Factor the denominators of both fractions

\frac{9}{(a+4)(a+5)} , \frac{7a}{(a+4)(a+7)}

The lowest common denominator of both fractions is (a + 4)(a + 5)(a + 7)

Multiply numerator/denominator of first fraction by (a + 7)

Multiply numerator/denominator of second fraction by (a + 5 )

\frac{9(a+7)}{(a+4)(a+5)(a+7)} , \frac{7a(a+5)}{(a+4)(a+5)(a+7)} , then

\frac{9a+63}{(a+4)(a+5)(a+7)} , \frac{7a^2+35a}{(a+4)(a+5)(a+7)}
