Answer:

The system has one solution.

Step-by-step explanation:

To find the number of solutions of the system, we equal both equations for y.

If we have ax = b, in which both a and b are different of 0, we have one solution.

If both a and b are 0, we have infinite solutions.

If a is 0 and b is not, there are no solutions.

y=6/7x-8 and y=7/9x+10/9

So

$\frac{6x}{7} - 8 = \frac{7x}{9} + \frac{10}{9}$

$\frac{6x}{7} - \frac{7x}{9} = \frac{10}{9} + 8$

$\frac{54x - 49x}{63} = \frac{10}{9} + \frac{72}{9}$

$\frac{5x}{63} = \frac{82}{9}$

$45x = 63*82$

Both a and b are different of 0, so the system has one solution.

Here, we are required to identify the dependent and independent variables, the dependency relationship in the situation.

The independent and dependent variables are the weight of the dog and the amount of food it should respectively.
The dependency relationship is thus; The amount of food a dog should eat is a function of the weight of the dog
The dependency relationship using the function notation is; f(x) = {function of x}.

The independent variable in this situation is the weight of the dog while the amount of food the dog should eat is the dependent variable. The above is evident from the statement; The amount of food a dog should eat depends on the weight of the dog.

According to the premise given in the question, it is evident that the dependency relationship is;. The amount of food a dog should eat is a function of the weight of the dog
