Answer:
12. x = 48
13. x = 7
Step-by-step explanation:
x/6 = 8
x = 8*6
x = 48
28 = 4x
28/4 = x
x = 7
Answer:
439cor.to 3 Sig. fig.
Step-by-step explanation:
(5+12)×6×14-(5÷2)²π×14
The x coordinate of the vertex will be the average of the two zeros, here -3 and 5, so x=(-3+5)/2 = 1, f(1)=(1+3)(1-5) = -16.
Answer: (1, -16)
Let's do it some other ways. How about completing the square to turn f in to vertex form?
f(x) = (x+3)(x-5) = x² - 2x - 15 = (x² - 2x + 1) - 1 - 15 = (x-1)² - 16
and now we can read off (1, -16) as the vertex.
The other method is the vertex is x= - b/2a = - (-2)/2(1) = 1.
Three methods, same answer. Good.

Answer:
Sheldon have left of food.
Step-by-step explanation:
Quantity of food = kg
Quantity used on strawberry plant =
Quantity used on tomato plant =
Food left = Total - used on strawberry - used on tomato
Food left =
Food left =
Food left =
Therefore,
Sheldon have left of food.
