Answer:
$675
Step-by-step explanation:
Let
x = original price of laptop
Discount = 10%
Actual price paid = x - 10% of x
= x - .10x
= .90x
Cost of mouse = $13.99
Total amount paid = $621.49
Total amount paid = actual cost of laptop + Cost of mouse
621.49 = .90x + 13.99
621.49 - 13.99 = .90x
607.5 = .90x
x = 607.5 / .90
= 675
Original cost of the laptop = $675
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.

Answer:
y=3x-4
Step-by-step explanation:
The fractions less than 1/2 are:
A. 1/3
C. 2/5
Answer:
w=2, -3
Step-by-step explanation:
minus 25 from each side
1+-25+4w^2+4w=25+-25
combine like terms
-24+4w^2+4w=0
factor out the greatest Common factor
4(-6+w+w^2)=0
factor a trinomial
4((-3+-1w)(2+-1w))=0
I hope this helps!
