Hello,
Let's r the ration
We suppose x ≠0
x=r*(x-2)==>r=x/(x-2)
x+3=r*x==> (x+3)/x=x/(x-2)==>(x+3)(x-2)=x²
==>x²+3x-2x-6=x² ==>x-6=0==>x=6
x-2=6-4=4
x=6
x+3=6+3=9
6=4*3/2
9=6*3/2
Ration 3/2
First term: 4

Answer:
Answer:
d--22→ 28
d→ 50
Step-by-step explanation:
Let d dollars be the initial amount in your bank account.
We have been given that you spent $22, so the amount left after spending $22 will be: .
We are also told that after spending $22, you have at least $28. This means that the amount left after spending $22 will be greater than or equal to $28.
We can represent this information in an equation as:
Therefore, the inequality represents the initial amount of money you had.
Now let us solve for d by adding 22 to both sides of our inequality.
Therefore, initially you had at least $50.

Using it's concept, it is found that the domain of the function ![f(x) = \sqrt[4]{x}](https://tex.z-dn.net/?f=f%28x%29%20%3D%20%5Csqrt%5B4%5D%7Bx%7D)
is given by:

<h3>What is the domain of a function?</h3>
It is the <u>set that contains all possible input values for the function</u>.
In this problem, we have the fourth root, which is an even root, that can only be calculated for non-negative values, hence the domain is given by:
A. .
