Answers
The coordinates of point A are (2, -2)
If the picture is translated 3 units to the left, we need to subtract 3 units to the x coordinate as:
( 2 - 3, -2) = (-1, -2)
Then, if the picture is translated 5 units up, we need to sum 5 units to the y-coordinate as:
( -1 , -2 + 5) = (-1, 3)
So, the coordinates of A' are (-1, 3)

Answers
We can conclude that (4,0) is the solution of the equation 3x + y = 12 with the correct option (A).
What exactly are equations?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign.So, the ordered pair of the equation 3x + y = 12:
(A) When (2,5):
3x + y = 123(2) + 5 = 126 + 5 = 1211 ≠ 12(B) When (4,0):
3x + y = 123(4) + 0 = 1212 + 0 = 1212 = 12(C) When (0,6):
3x + y = 123(0) + 6 = 120 + 6 = 126 ≠ 12Therefore, we can conclude that (4,0) is the solution of the equation 3x + y = 12 with the correct option (A).

Answers
Old-Tyme Fashions needs to sell 9 hats to break even at a price of $69 each.
Given, Old-Tyme Fashions specializes in hats modelled after fashions from the past.
It purchases these hats for $42 each.
It can provide a custom service to print the new owner’s name on the hatband.
The printing machine costs $243 per month to rent. If Old-Tyme sells the hats at a price of $69 each, how many does it need to sell to break even=?
The cost function to make n hats is:
C(n) = 42*n + 243 dollars.
The revenue function is
R(n) = 69*n dollars.
The break event equation/inequality is
R(n) ≥ C(n), or
69*n ≥ 243 + 42*n.
Simplify and solve for n:
(69-42)*n ≥ 243
27n ≥ 243
n ≥ 243/27 = 9.
hence 9 hats should be sold to break even.
