Answer:
exponential growth.
f(x)=253,980 (times) X (years)
f(x)=256,000(times) X (years)
it will be the same
Answer:
The correct answer is the value of x is 4 and y is 1 respectively.
Step-by-step explanation:
The system of equations are −5x + 13y = −7 and 5x + 4y = 24.
To solve for x and y.
For solving we add both sides of the given system of equations.
∴ −5x + 13y + 5x + 4y = 24 - 7
⇒ 17y = 17
⇒ y = 1
⇒ x = 4
Thus the values of x and y are 4 and 1 respectively.
