Answer:
126
Step-by-step explanation:
By cyclic quadrilateral theorem:

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.
Answer:
A: 18x+15
Step-by-step explanation:
5(4x+3)-2x
Distribute the 5
20x +15 - 2x
Combine like terms
20x-2x +15
18x +15
Ok so for starters you want to choose an equation and solve for a variable.
So, I am going to choose x from the first equation.
Add y to both sides and you get x=11+y
Next, substitute 11+y for x in the other equation so you get...
2(11+y) +10y=-6
Next distribute the 2 throug the 11 and the y
22+2y+10y=-6
12y=-28
y=-28/12
reduce this fraction to make this easier.
y=-7/3
Now plug in why to either of the equations to find x
x-(-7/3)=11
x+7/3=11
x=11-(7/3)
x=(33/3)-(7/3)
x=26/3
so x = 26/3 and y = -7/3
you can also check to see if this is correct by substituting each of these values into the equations.
your answer for this question is y=c hope this helps
