Veronika [31]
Let's use the SAS postulate! SAS means Side, Angle, Side. I would sometimes write this the other way and get in trouble, haha. 
It technically means if a triangle that has a congruent angle between two congruent sides, it means it is congruent. Here is a picture.

Naya [18.7K]

To solve this problem you must apply the proccedure shown below:

1. You have the following information given in the problem above:

a- \frac{3}{4}of acne employees receive raises.

b- \frac{1}{3} of those who receive raises also receive bonuses.

2. Therefore, you must multiply both fractions, as following:

(\frac{3}{4} )(\frac{1}{3} )=\frac{3}{12}

3. Now, simplify the expression:

\frac{3}{12} =\frac{1}{4}

The answer is: \frac{1}{4}

The inverse of the function y = 9 - x 2, for all values x ≥ 3, is _____, where x can take values _____.
anastassius [24]
Inverse of y=9-x²; you just replace x by y and y by x: x=9-y².

And the value of y:    y² = 9-x  and y =√(9 - x) [this is the inverse function]

f⁻¹(x) = √(9-x): CONDITION :  (9-x) >=0, that means x< or = 9
 
Answer as per your problem:

The inverse of the function y = 9 - x 2, for all values x ≥ 3, is _____y =√(9 - x), where x can take values _____x<=9.
