Answer:
C
Step-by-step explanation:
Since these lines have the same slope and different y-intercepts, they are parallel lines. As such lines do not intersect, we can say that :
The system has no solutions.
20 i think sorry if its wrong not my best subject.
Answer:
(11,6)
Step-by-step explanation:
I just took the test and it was this answer.
Answer:
1A) Degree: 3
1B) 4 terms
1C) 
2A) 
2B) 
Step-by-step explanation:
The given polynomial is 
Let us rewrite the polynomial in decreasing powers of x.
This gives us the expression;
-----> This is called the standard form.
So let us answer the question:
A) The degree is the exponent of the first term when the polynomial is written in standard form.
Degree: 3
B) The terms are separated by + or - signs.
Number of terms: 4
C) Standard form:
2A) The given expression is 
We expand using the distributive property to get:
We regroup the terms to get:
We simplify to obtain:
2B) The given expression is 
Regroup the terms to get:
We simplify to get:
