Answer:
The value of n depends on the questin. N would be a variable in an equation.
Step-by-step explanation:
For example. 2*n=6
n is the variable in the equation. Therefore, the value of n is 3. Because 2*3=6.
The equation of the line for this question can be stated as,
What does y = when x is -1 or
What does x = when y is 2
So since the slope of the line is 2, we can assume that B and C must be the answers but since you want one answer we need to be more accurate.
The answer is C
Because when y = 0 x = -1 and when y = 2 x = 0
Because he needs less than (note that he didn't say he needs no more than) 6 pounds, first inequality is C) x+y<6
Now in inequalities that have 7 and 5 in them, 7 represents the cost of first ingredient and 5 the cost of second ingredient. If we multiply each of that number with quantity of that ingredient and sum both up we get the price of the mixture.
Because he says that he wants that mixture costs no more than 30 that means that it costs less than 30 but 30 can be the answer as well.
The last answer is E) 7x + 5y
