The interpretation of 0 = -12 is (a) There are no solutions to the system because the equations represent parallel lines.
<h3>How to interpret the result?</h3>
The result is given as:
0 = -12
By comparison 0 and -12 do not have the same value
i.e. 0 ≠ - 12
This means that the system of equation has no solution
Hence, the interpretation of 0 = -12 is (a)

Answer:
Step-by-step explanation:
1. x = y-4
0 = y - 4 -x
4 = y - x
2. 2x+4y = 10
x+4y = 5
x+y = 5/4

Answer:
(c) 52.0
Step-by-step explanation:
The angle whose cosine is 8/13 is found using the inverse cosine function:
y° = arccos(8/13) ≈ 52.0°
y ≈ 52.0

The calculator button to compute this value is probably labeled cos⁻¹. You may need to access the function using a <em>Shift</em> or <em>2nd</em> key. The calculator must be set to degrees mode to prevent the answer from appearing in radians or grads. If you use a spreadsheet, your formula may look like ...
=DEGREES(ARCCOS(8/13))
