b)3

c)0

d)2

Step-by-step explanation:

to find the degree of the polynomial just look at the exponents. The highest exponent you see is the answer. For polynomials with variable but no exponents (like in a) the degree is technically 1 for that expression. if there is just a digit with no exponent (like in c) then the degree is 0

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .
