Well what does star equal?
To find the x value of the vertex we do:
x =

if your quadratic function is in the form ax² + bx + c = y
x =

x =

Now we plug this x into the equation and solve for y.
y =

y =

y =

y =

y =

y =

Your vertex (if my math is correct) is at
By proportion. First write down the given information systematically:
[1000] drops of liquid equals (1 fl. oz.)
(100) drops of liquid equals ? oz
For problems that are directly proportional, we cross multiply the numbers in the bottom left and top right (in parentheses), divide by the number across ( in square brackets) from the unknown, namely:
Answer:
100 drops * 1 fl. oz / (1000 drops) = (100/1000)* 1 fl. oz = 0.1 fl. oz.
Answer:
y = -x + 6
Step-by-step explanation:
<u>Use point slope form: (y - y1) = m(x - x1)</u>
m is -1
<u>Step 1: Plug in</u>
(y - (-4)) = -1(x - 10)
y + 4 - 4 = -x + 10 - 4
y = -x + 6
Answer: y = -x + 6
