Answer:22
Step-by-step explanation: divide 46.2 by 14 to get 3.3 then divide 72.6 by 3.3 easy way but there is a harder one I just forgot lol
The answer would be 14/5.
First of all, get the denominators to be the same. The LCM is 5
×
7
=
3/5
So 1
/7
×
5/
5
=
5
/3/5
And 2/
5
×
7
/7
=
14
/35
Now we have 5
/35 and 14
/35
Then all you have to do is divide Joe's by Jane's to get the answer.
14
/35
÷
5

=14
/35
×
35/
5
=
14
/5
Meaning the answer is 14/5.
Hope I could help! :)
F(x) = 8.
This is a constant function. No matter the value of x, f(x) will always be = 8
Therefore when x = 10, f(x) = 8.
Answer: 
<u>Step-by-step explanation:</u>
y = 8x² - 3 (Restriction: none - x is All Real Numbers)
The inverse is when you swap the x's and y's and then solve for y
x = 8y² - 3 <em>swapped the x and y</em>
x + 3 = 8y² <em>added 3 to both sides</em>
<em>divided both sides by 8</em>
<em>square rooted both sides</em>
<em>simplified</em>
rationalized the denominator
<em>simplified</em>
<em>simplified</em>
<u>Restriction:</u>
The radical <em>(inside the square root sign)</em> cannot be negative
→ 2(x + 3) ≥ 0
x + 3 ≥ 0 <em>divided both sides by 2</em>
x ≥ -3 <em>subtracted 3 from both sides</em>
Answer:
f(n) = n/36
Step-by-step explanation:
The length of a string is given in yards, is a function f(n) of the length n in inches.
We have to write a function rule for this situation.
∵ 36 inches = 1 yard
∴ 1 inch = 1/36 (yard)
∴ n inches = n/36
and function representing the length will be
f(n) = n/36
