Answer:
c. The system is inconsistent
Step-by-step explanation:
Multiplying the first equation by 2 gives ...
4x +2y = 4
Compare this to the second equation:
4x +2y = -5
There are no values of x and y that can satisfy both equations. The system is inconsistent.
_____
The equations describe lines that are parallel and do not intersect.
Answer:
- 4
Step-by-step explanation:
Using the rule of exponents
•
×
⇔ 
•
⇔ 
=
= 
and right side
=
× 
Hence
=
× 
= 
Equating exponents on both sides gives
a + 10 = - 2a - 2 ( add 2a to both sides )
3a + 10 = - 2 (subtract 10 from both sides )
3a = - 12 ( divide both sides by 3 )
a = - 4
The answer for this multiple choice is D
