Can u pls help me with this question asap
Zinaida [17]

Answer:

3.5/1 (or just 3.5)

Step-by-step explanation:

If y = a/n, then the constant proportionality is 3.5/1 or 7/2

Think of this as "rise over run" (we are basically finding the slope)

13. Which system of inequalities has no solution?
Anit [1.1K]

Answer:

Option A

Step-by-step explanation:

We have y < 2x - 4 and y > 2x + 1.

=> 2x - 4 > 2x + 1

=> -4 > 1

Since this inequality is false for all real values of x, there is no solution for the system of inequalities.
