Answer: -x^2 + 2x - 3

Step-by-step explanation:

(x^2 - 3x) + (-2x^2 + 5x - 3)

Combine like terms

x^2 - 2x^2 - 3x + 5x - 3

x^2 - 2x^2 = -x^2

-3 + 5x = 2x

X - y = 3<br> x + 3y = 9
Ugo [173]
Solve for one of the variables in the first equation (in this case, I will solve for X):
X = Y + 3

Then use that value of X in the second equation to solve for Y:
X + 3Y = 9
(Y + 3) + 3Y = 9
4Y + 3 = 9
4Y = 6
Y = 1.5

Use the value of Y we just found in the X equation we created:
X = Y + 3
X = 1.5 + 3
X = 4.5

Therefore X = 4.5 or 9/2 and Y = 1.5 or 3/2.

horsena [70]

David purchased some cookies at the cost of

5 for $4 (5/4=1.25) and


sold them at 4 for $5(4/5=0.80).


To find cost per cookie subtract 1.25-0.80=0.45


David made a profit of $180 in total ( divide profit per cookie cost: 180/0.45= 400)


How many cookies did David purchase to make that much money?


He needed to make 400 cookie to make the profit of $180.
