Answer:
Step-by-step explanation:
Both equations of this system are of degree one.
They are both linear as the graph of both is a line.
The direct variation between x and y may be written as,
y = kx
where k is the constant of variation. From the first set of values of the variables,
12 = k(8)
the value of k is 1.5. Substituting the next set to the same equation,
y = 1.5(14)
The value of y is 21.
Answer:x=(y-25)/15
Step-by-step explanation:
If you divide a negative by a positive then you get a negative or if you divide a positive by a negative then you make that number negative
