------- = y
-4
Answer:
(-1/2, 23/4)
Step-by-step explanation:
Vertex of graph: -b/2a
b=1
a=1
Therefore, -1/2 is your x-value
Solve for y: y=1/4-1/2+6
y=5 3/4 or 23/4
Therefore your vertex is: (-1/2, 23/4)
The answer is 47.85 because you're just multiplying the percentage to the given number, but first, convert the percentage into a decimal.
90 grams are equivalent to 0.09 kilograms and 55 grams are equivalent to 0.055.
So 0.09 + 0.055 = 0.145.
0.145 * 12 = 1.74
So 1.74 kilograms of sugar is needed to make 12 crisps.
