Answer:
y = 4x; there are an infinite number of solutions
Step-by-step explanation:
Both equations describe the same relation between x and y. The system is "dependent", so has an infinite number of solutions. For any value of x, the solution is ...
(x, y) = (x, 4x)
If the population quadruples every period say hour, that means the "rate of growth" is 300%, so whatever the current amount, increased by 3 times as much is 4 times the current amount, or a quadrupled amount.
Answer:
B
Step-by-step explanation:
2^2 x 2^3 = 2^5
2^5/2^4 = 2^1
(-16+12)/(-4+2)= (-4)/(-2)= 2
