X is less than or equal to $30, she can spend $30, she cant spend more, she can spend less.
The answer should look like X<30 with a line under the less than sign, i hope this helps.
The system of equations that represents the situation is given by:
C. x² – 2y ≥ 5000, 2x + 5y < 1000
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In tis problem, the company's stock is represented by the expression x² - 2y, and the goal is a stock value of at least $5,000, hence the first equation is given by:
x² – 2y ≥ 5000
The purchases are represented by 2x + 5y, and the goal is to keep it below $1,000, hence the second equation is given by:
2x + 5y < 1000
This means that option C is correct.

A={a,b,c}, B={9,16,25}, and f={(a,9),(b,16),(a,25)}. True or false, f is a function from A to B?

Answer: False</h3>
Explanation:
The input x = a leads to multiple outputs y = 9 and y = 25 at the same time. This is due to the points (a,9) and (a,25) in the set f.
A function can only be possible when any x input leads to exactly one y output only. You'd need to get rid of either (a,9) or (a,25) to make this a function.
The GCF of 56 and 21 is: 7
Factors of 21: 1, 3, 7, 21
Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56
7 is the highest common factor that appears in both of the given numbers.
