For this case we have the following system of equations:

We multiply the first equation by -1:

We have the following equivalent system:

We add the equations:

Equality is not fulfilled, so the system of equations has no solution.
Answer:
Option C
<h2>
Answer:</h2>
The ratio is a fraction that tells us how many times longer a thing is compared to another thing. In mathematics, we express a ratio as the relationship between two numbers, namely
, so the ratio can be written as:

If we can change this number without changing the ration we need to multiply both the numerator and the denominator by the same number. For instance, if we have the following ratio:

We can multiply both the numerator and denominator, say, by 7. Then:

As you can see, the ratio's number has changed but without changing the ratio itself because:

Answer with explanation:
Presume that, initial water level to be, 0 mm, at a time t=0.
And water level is rising at the rate of
.
After 6.2 years level of water will be =1.8 × 6.2
=11.16 mm
→Averge, that is increase in water level after 6.2 years is given by

→→Rate of Depreciating of water level is given by = Negative of Increase of water level=

-6,1
step by step
first you sympypfly the answer and then what you want to do is mutyplying te answer by the formula of the graph by then you should already have the table of the formula,then what you want to do is to try to coordinate the number of the graph,AND THA'S HOW YOU GET (-6,1)
