Answer:
See explanation, and ask for more details if unclear!
Step-by-step explanation:
The perfect square of this equation is 
, since the square would be 
. 1/4=4/16, meaning that you can set up the equation in the following way:
Take the square root of both sides:
Add 1/2 to both sides:
. Hope this helps!
Answer: y = x -1
reasoning: the slope is 1 because the rise/run = 1/1, which simplifies to 1.
the y intercept is -1 because the line passes through the y axis at -1.

Answer:
134 sneakers and 66 sandals
Step-by-step explanation:
Sneakers= x, sandals= y
Profit rate:
- sneakers: (10-2)/8= 25%
- sandals: (17-14)/14= 21.4%
Sneakers are more profitable, so it should be maximized.
Cost:
8x+14y≤2000
x+y≤200
if we assume the maximum of 200 shoes stocked, then:
x= 200-y
8(200-y)+14y ≤ 2000
1600 - 8y +14y ≤ 2000
6y≤400
y≤66 and x=134 is the best option
Answer:
y = -6/5x - 5.6
Step-by-step explanation:
6x + 5y = 6
-6x -6x
5y = -6x + 6
/5y /5y
y = -6/5y + b
-2 = -6/5(-3) + b
-5.6 = b
(20×30)÷100= 6$ is how much you saved
