Answer: 195
Step-by-step explanation:
Given : The number of cans the soup kitchen has is represented by the equation, , where x represents the number of days and y represents the number of cans.
To find : The number of cans in the soup kitchen have left after 10 days, we need to put x= 10 in the above equation, we get
Hence, 195 cans the soup kitchen have left after 10 days.

Answer:
Step-by-step explanation:
Given
x² - 3x
To make the expression a perfect square
add ( half the coefficient of the x- term )²
x² + 2( - )x +
, thus
x² - 3x +
= (x - )² ← a perfect square
Answer:
40 copies for $3000
Step-by-step explanation:
First: The Equation
y=(20+x)(100-x)
This shows how for every new painting, the price will go down.
y=2000+80x-x²
Convert it to standard form: ax²+bx+c
You can now choose to graph it or find the vertex form. For the limit of time, I will just use a graph.
The vertex, (40,3000), is your answer, where the x value is the number of paintings and the y value the money made.
