Answer:
x y
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
4/3 2
8/3 10/3
22/3 24/3
Hope this helps!
Answer:

22/3 8
Step-by-step explanation:
y=x+2/3
2=x+2/3
2-2/3=x+2/3-2/3
6/3-2/3=x
4/3=x
y=x+2/3
y=8/3+2/3
y=10/3
y=x+2/3
y=22/3+2/3
y=24/3

Find the missing values in the ratio table. Then write the equivalent ratios. People 6 18 Benches 3 12 a The equivalent ratios are 6 : 3, : 12, and 18 : . Skip to navigation
Answers
The missing values in the ratio table are;
⇒ 6 : 3 , 24 : 12, and 18 : 9
What is mean by Ratio?
A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y.
Where, x and y are individual amount of two quantities.
And, Total quantity gives after combine as x + y.
Given that;
Peoples = 6 , 18
Benches = 3, 12
Now,
The equivalent ratios are;
⇒ 6 : 3 , x : 12 , 18 : y
Find the values of x and y as;
Since, All the ratio are equivalent.
So, we get;
⇒ 6 : 3 = x : 12
⇒ 6 / 3 = x / 12
⇒ 6 × 12 / 3 = x
⇒ x = 24
And, ⇒ 6 : 3 = 18 : y
⇒ 6 / 3 = 18 / y
⇒ 6 × y = 18 × 3
⇒ y = 18 × 3 / 6
⇒ y = 9
Thus, The missing values in the ratio table are;
⇒ 6 : 3 , 24 : 12, and 18 : 9

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

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.

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]

therefore, x = [tex]\sqrt{25*4}[/tex] = [tex]\sqrt{100}[/tex] = 10

Grant mows lawns for extra money. He mows 9 lawns in 9 hours on Wednesday and 6 lawns In 6 hours on Saturday.
What is the constant of proportionality that relates the total number of lawns mowed, y, to the number of hours mowing lawns, x?

It would be y=x or x=y as we can see that 9 lawns in 9 hrs equal 1 lawn in 1 hr. 6 lawns in 6 hrs equals to 1 lawn in 1 hr as well.

Equation at the end of step 1

:
Trying to factor by splitting the middle term
2.1 Factoring 2d2-3d-2
The first term is, 2d2 its coefficient is 2 .
The middle term is, -3d its coefficient is -3 .
The last term, "the constant", is -2
Step-1 : Multiply the coefficient of the first term by the constant 2 • -2 = -4
Step-2 : Find two factors of -4 whose sum equals the coefficient of the middle term, which is -3 .
-4 + 1 = -3 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -4 and 1
2d2 - 4d + 1d - 2
Step-4 : Add up the first 2 terms, pulling out like factors :
2d • (d-2)
Add up the last 2 terms, pulling out common factors :
1 • (d-2)
Step-5 : Add up the four terms of step 4 :
(2d+1) • (d-2)
Which is the desired factorization
Final result :
(d - 2) • (2d + 1)
