If you substitute the values x = 0 and y = −5 into the second equation, you get a false statement: 2(−5) − 10 = 2(0). To solve this system, try rewriting the first equation as x = 2y − 8. Then substitute 2y − 8 in for x in the second equation, and solve for y. The correct answer is x = −2, y = 3.

Answer:
37.7 yd
Step-by-step explanation:
The circumference of a circle can be found using the formula ...
C = 2πr
For a radius of 6 yd, the circumference is ...
C = 2π(6 yd) = 12π yd ≈ 37.7 yd
The length of the circular border was 37.7 yards.
Answer:
A.
exponential
Step-by-step explanation:
Exponential is best suited here because life span gradually increases from b to a over the years continuously. Whenever there is a continuous steady increase, exponential function is more suitable.
Logrithamic function will not suit because rate of change of log is 1/x and if x population is very large this will be almost equal to 0 which is not correct.
But exponential say a^x rate of increase= a^x log a and when a is small this will represent a slow steady state of increase.
Step function will not suit as step functions are discontinuous at every integral value, but the population function is a continuous function.
Absolute value function is suitable only for functions symmetrical about a particular value of x or y
But here there is no symmetry but steady increase. Hence exponential is the best suitable graph.
