Answer:
D: y=6x
Step-by-step explanation:
y=mx+b
b=0
y=mx
-3=m * (-1/2)
m=6
y=6x
Answer:
Product = 
Step-by-step explanation:
The expression is as follows :

We need to find the product of the above expression
As 7 × 2 = 14
So, it will become :

So, the product of the given fractions is
.
First, we need to know how much profit in dollar value by this method
profit = percentage × whole price
Plug in the numbers to the formula above
profit = percentage × whole price
profit = 40% × 25
profit = 0.40 × 25
profit = 10
The profit Daniel gets is $10
Second, add the original price and the profit together and you'll find the new price.
new price = original price + profit
new price = $25 + $10
new price = $35
Daniel sold the computer game for $35
Answer:
The width which gives the greatest area is 7.5 yd
Step-by-step explanation:
This is an application of differential calculus. Given the area as a function of the width, we simply need to differentiate the function with respect to x and equate to zero which yields; 15-2x=0 since the slope of the graph is zero at the turning points. Solving for x yields, x=7.5 which indeed maximizes the area of the pen
