B. 12n=78
Step-by-step explanation:
Answer:
No. This isn’t a function.
Step-by-step explanation:
Ok, functions have x values that only have 1 y value. It doesn’t matter if the y values have multiple x values.
So, first look at the x values, all of them have 1 y value but the number 6. Therefore, this does not represent a function.
The answer is the 2nd one.
Answer:
$7.68
Step-by-step explanation:
You must find the rate first, so in order to do that you divide the price by the quantity which is
3.20/5
which equals .64 and this number is the cost of potatoes per pound so to find 12 pounds you do
.64 * 12
which equals 7.68
5(3x+7)=3(5x+7)
15x+35=15x+21
cancel out the 15x. If you bring over one of the 15x it's going to naturally cancel each other out.
35=21
35 does not equal 21
it would be the equal sign with the slash coming through it
