To solve this problem you must apply the proccedure shown below:
1. You have the following parent function given in the problem above:

2. And you have the function 
3. By definition, if you have the function
and
it is a vertical stretch.
4. Therefore, you have that:

Therefore the answer is: It is a vertical stretch.
The second sentence is correct.....
Solving the second equation for y..
2x-y=7 divide both sides by -1
y-2x=-7 add 2x to both sides
y=2x-7
When a solution exists, y=y, so we can say:
2x-7=2x+3 subtract 2x from both sides
-7=3
-1 != 3
Since the above is never true, there are no solutions to this system of equations.
Intuitively, this is because both lines have the same slope, they are parallel, and have an different y-intercept, thus they will never cross each other...
Answer:
The chef uses 5452.8 grams of butter each day.
Step-by-step explanation:
Given:
Chef use 12 pounds of butter each day.
To find the amount of butter in grams used by chef each day.
Conversion units:
1 pound = 16 ounces
1 ounce = 28.4 grams
Solution:
We need to convert 12 pounds of butter in grams of butter.
We will apply unitary method to carry out the conversion.
If 1 pound = 16 ounces
Then, 12 pounds = 
If 1 ounce = 28.4 grams
Then, 192 ounces = 
Thus, the chef uses 5452.8 grams of butter each day.
