Answer:
Option (D).
Step-by-step explanation:
Initial population of the deer = 4800
Decrease in the population of the deer after every 8 years =
Decrease in population is an exponential process, so the expression representing population will be,
Where is the population after 'x' slots of 8 years.
r = fraction of decrease in the population
x =
By substituting the values of r and x in the expression,
Therefore, Sylvia should do few corrections in her expression.
(8) should be replaced by () and should be replaced by .
Option D. will be the answer.
2 y = - x - 12 y = x + 5
- x - 1 = x + 5- 2 x = 5 + 1- 2 x = 6x = - 6 : 2x = - 32 y = - 3 + 52 y = 2y = 1The solution is ( - 3 , 1 ).Answer: x = - 3.
Answer:
We have been given an equation
We will factorize it by middle term splitting.
Step 1:
Taking common factors out by clubing first two terms ad last two terms
Step 2:
Step 3:
Equating both above factors to zero as:
Step 4:
And .
Answer:
13
Step-by-step explanation:
7 more waiters than cooks
w = 7 + c
w = 7 + 6
