Answer: When a system of two linear equations gives an answer of 
, there are infinitely many solutions. It also means that the graph represents parallel lines, so the answer is the third choice.
Step-by-step explanation: When it comes to systems of equations in algebra, you will see three types of solutions:
1. When you get an exact value & number for x and y, the system has <u>one solution</u> and is consistent/independent.
2. When you get like in this case, the system has <u>infinitely many solutions</u> and is consistent/dependent.
3. When you get numbers that are not equal, for example, 
, you have <u>many solutions</u> and the system is inconsistent/independent.

Answer:
x = −
4 ± √
10,
Step-by-step explanation:
2(x + 4)² = 20
=> 2(x + 4) (x + 4) = 20
=> 2x + 8 (x + 4) = 20
=> 2x² + 8x + 8x + 32 = 20
=> 2x² + 16x + 32 = 20
=> 2x² + 16x + 12 = 0
=> Now solve using the quadratic formula:
x = −
4 ± √
10,
Radical form: −
4 ± √
10,
Decimal form: -0.84, -7.16
