Answer: 
Step-by-step explanation:
Rewrite the function as following:
Now, you must solve for x as you can see below:
Rewrite it as following:
Now substitute x=9 into the function above, then, you obtain:
The correct answer is b.
A polynomial is an expression that contains terms with the form ax^n where a is equal to any number (negative or positive) and n is the power, or exponent, of x (squared, cubed, etc.). In order for it to be a polynomial, the exponent must be positive. Terms that contain square roots are not polynomials as the exponent is considered radical (1/2). Thus, b is the correct answer.
Dang, I'm only 12 I don't knowwwww
C= 28.8
A=29.9
B=30.1
Just count the lines.
Answer:
Lines a and b are parallel to each other! ... The same-side interior angle theorem states that when two lines that are parallel are intersected by a transversal line, the same-side interior angles that are formed are supplementary, or add up to 180 degrees.
