Answer:
The answer is A
Step-by-step explanation:
In order for it to be a function every x value has to have a different y value or every input has to have a different output.
Answer: The variable 
represents the number of packages of corn.
Step-by-step explanation:
1. You have the following expression given in the problem:
2. Then, if the expression represents the cost of the corn for a number of packages, then the price of a package (which is $3.59) must be multiplied by the number of packages (which must be represented by the variable ).
3. Therefore, you can conclude that the variable represents the number of packages of corn.
Answer:
27+5x
Step-by-step explanation:
Answer: <em>The slope is 1 </em>
Step-by-step explanation:
(0, 2.7) - x1, y1
(1, 3.7) - x2, y2
3.7 - 2.7 = 1
1 - 0= 1
1/1 = 1
Answer:
W = 16
L = 24
Step-by-step explanation:
Let's write down the information we have first
"The length of a rectangle is 8 feet longer than it is wide"
L = W + 8
"If each side is increased 8 feet, then the area is multiplied by 2."
(L + 8)(W + 8) = 2LW
Now we can solve for W first, then L
(W + 16)(W + 8) = 2W(W + 8)
W² + 24W + 128 = 2W² + 16W
0 = W²- 8W - 128
0 = (W - 16)(W + 8)
W = 16
L = 24
(This part above is solved like quadratics)
