So baically
reresent
s=number of studne tickes bouthgt
a=number of adult tickets bought
300 tickest sold
total=300
a+s=300
value=rate times number of peple
student value=4s
adults value=10a
total value=1950
4s+10a=1950
a. system of equations are
s+a=300
4s+10a=1950
b. solve
s+a=300
4s+10a=1950
a+s=300
multiply by -4
-4s-4a=-1200
add to other eqaution
4s+10a=1950
<u>-4s-4a=-1200 + </u>
0s+6a=750
6a=750
divide 6
a=125
subsiute
s+a=300
s+125=300
subtract 125
s=175
a. s+a=300
4s+10a=1950
b. solution above
175 students
125 aduls
14. The answer is A; 8 is the opposite reciprocal of -1/8, which is what you need for perpendicular slope.
15. The answer is C; you can guess and check by plugging points into the equation.
Break the two denominators down to their primes.

Is all
Answer:
They all are polynomials.
Step-by-step explanation:
Given : Following expression
1) 
2) 
3) 
4) 
The following all are polynomials because polynomials are:
An expression consisting of variables and coefficients or expression more than two algebraic terms and the terms that contain different powers of the same variable(s) involve operations addition , subtraction, multiplication and non-negative integer exponent of variables.
So when we see to these functions they all are a mixture of a polynomial.
