Answer:
x = 3
Step-by-step explanation:
The formula for the axis of symmetry is x = -b/(2a).
Here, a = -2 and b = 12, so the axis of symmetry is
-12
x = --------- = 3 => x = 3
2(-2)
The answer is 13 if he puts all the bagels bit if he doesn't then it is 12 I put 12
Answer:
9x
Step-by-step explanation:
X is an unknown variable so just leave x as it is
Because the (2x) and the (7x) are being multiplied together they are almost seen as their own category of things
Think about having two bananas in a bowl. I just threw in seven more to get a total of nine bananas in the bowl.
It's the same thing when you have a variable right next to a number! add them together as if they are alike terms.
2+7=9 therefore your answer should be 9x
The first car needed 56.7 gallons

Answer:
6.12
1.39
4.12
12
Step-by-step explanation:
If y ∝ x, then y = kx.
So, the constant of proportionality is given by 
Case 1:
$18.36 for 3 pizzas
Therefore, the constant of proportionality is 
Case 2:
$4.17 for 3 pounds of bananas.
Hence, the constant of proportionality is 
Case 3:
$16.48 for 4 pounds of potatoes.
Hence, the constant of proportionality is 
Case 4:
2 cups of flour to make 24 cookies.
Hence, the constant of proportionality is
