Answer: b = 4 and c = 7.</h3>
===============================================
Explanation:
Comparing y = x^2+bx+c to y = ax^2+bx+c, we see that a = 1.
The vertex given is (-2,3). In general, the vertex is (h,k). So h = -2 and k = 3.
Plug those three values into the vertex form below
y = a(x-h)^2 + k
y = 1(x-(-2))^2 + 3
y = (x+2)^2 + 3
Then expand everything out and simplify
y = x^2+4x+4 + 3
y = x^2+4x+7
We see that b = 4 and c = 7.
Answer:
3/4
Step-by-step explanation:
We need two points to find the slope
( 20,20) and (60,50)
m = (y2-y1)/(x2-x1)
= (50-20)/(60-20)
= 30/40
= 3/4
Answer:2.5 part
Step-by-step explanation:
Given
Candle maker requires 1 quart of wax to make 6 candles
If candle maker makes 30 candles then 5 quart of wax is needed
The quart is made up of 2 part of red+ 5 parts of yellow + 3 Parts of white
i.e. total of 10 parts is required to make orange shade
Yellow is 5 part out of 10 part so
yellow will be 2.5 part in 5 quart
