Yes, this is a polynomial. It is an expression containing variables raised to a real number.
In this case, the variables are being raised to the power of one.
The degree of this polynomial, thus, is one.
Answer:
all real numbers
Step-by-step explanation:
C = -b + 12
2b - 3c = 1 1/2
2b -3(-b+12) = 1 1/2
2b + 3b -36 = 1 1/2
5b = 37 1/2
b = 37.5/5
b = 7.5
c + 7.5 = 12
c = 4.5
b = 7.5 c = 4.5
Hope this helps :)
