Answer:
a) 12x + 20y = 300
b) No
Step-by-step explanation:
You can define your variables however you like. Let x = number of caps and y = number of shirts.
Using the costs given the equation would be
12x + 20y = 300.
For part b the answer is no, only points with positive x and y values would be solutions, since you cannot have a negative number of caps or shirts.

Answer:
centre = (-5, -4)
radius = 7.42
Step-by-step explanation:
The general form for center-radius is
(x - h)² + (y - k)²= r²
Center = (h, k)
Radius = r
Rearrange the equation.
(x² + 10x) + (y² + 8y) - 14 = 0
Add 14 on both sides.
(x² + 10x) + (y² + 8y) = 14
(10/2)² = 25
(8/2)² = 16
Add 25 and 16 to both sides.
(x² + 10x + 25) + (y² + 8y + 16) = 14 + 25 + 16
Factor left side of the equation.
(x+5)² + (x+4)² = 55
(55) = (7.416198)²
(x+5)² + (x+4)² = 7.42²
The radius is 7.42.
The centre is at (-5, -4).
