10. Sanju wants to sell his artwork at a local fair. He has created 10 pieces of artwork and has spent $44 in creating them. He wants to make a profit of $300 at the fair. What is the price he needs to sell each piece to make that profit?
$344.00
$34.40
$24.67
$68.80

9) y>0 or y<−14 10) Each artwork sold for $34.4

Step-by-step explanation:

#9 is fairly easy, just plug in a calc and pull out ans.

#10 so he needs to make $300 + $44 in total to recover everything as he wants $300 more in profit. set up the equation:

$300 (Profit) + $44 (Initial) = 10 ( # of paintings) x (how much to be sold for

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
