Answer:
4 * 2y + 4 * 1
4(2y + 1)
Distributive property
Step-by-step explanation:
8y + 4
We can factor out a 4 out of both as both are divisible by 4
8y / 4 = 2y
4 / 4 = 1
So 8y + 4 is the same as saying 4 * 2y + 4 * 1
This can be written as 4(2y + 1) which is written using the distributive property

Answer:

4/3 2
8/3 10/3
22/3 24/3
Step-by-step explanation:
Substitute y with 2 for the first problem
2=x+2/3
Subtract 2/3 on both sides:
4/3
Thus:
x y
4/3 2
Now Substitute x with 8/3 for the second problem
y=8/3+2/3
Add:
y=10/3
Thus:
x y
8/3 10/3
Now Substitute x with 8/3 for the third problem
y=22/3+2/3
Add:
y=24/3
Thus:
x y
22/3 24/3
Thus the Full equation is:
x y

A population of caribou in a forest grows at a rate of 3% every year. If there are currently 208 caribou, which function represents the number of caribou in the forest in t years?
Answers
Answer:
f(x)=208^0.3x
Step-by-step explanation:
Think of this as a graph. You start out with 208 caribou, which is your y intercept, as it is there when the growth is 0.
The generic formula fr an exponential equation is a^x.
A represents your initial value. In this case, its 208
x represents the growth. In this case, it's 0.3%.
Your equation should be f(x)=208^0.3x

Find the value of x in the isosceles triangle shown below
Answers
Answer:
x = 10
Step-by-step explanation:
if there 2 same triangle then they are right triangle
By using Pythagorean theorem for 1 of right triangle, we have
[tex]\sqrt{74} ^{2}[/tex] = [tex]7^{2}[/tex] + [tex](\frac{x}{2}) ^{2}[/tex]
74 = 49 + [tex]\frac{x^{2}}{4}[/tex]
74 - 49 = [tex]\frac{x^{2}}{4}[/tex]
25 = [tex]\frac{x^{2}}{4}[/tex]
therefore, x = [tex]\sqrt{25*4}[/tex] = [tex]\sqrt{100}[/tex] = 10

A jar is filled with quarters and nickels in the ratio 1 2/5 to 2 1/3. If there are 24 quarters in the jar, what is the ratio in dollar value of quarters to that of the nickels???
Answers
Answer:
3 : 1
Step-by-step explanation:
The ratio of coins is ...
1 2/5 : 2 1/3 = 7/5 : 7/3 = 3 : 5
The quarters have 5 times the dollar value of nickels, so the ratio of dollar values is ...
5(3) : 5 = 3 : 1
The quarters have 3 times the dollar value of the nickels.
__
Additional comment
The number of nickels is 5/3 times the number of quarters, so is 5/3(24) = 40.
The dollar value of the quarters is 24($0.25) = $6.
The dollar value of the nickels is 40($0.05) = $2.
As above, the ratio of dollar values is 6:2 = 3 : 1.
