The vertex of this parabola is at (2, -4). When the y-value is -1, the x-value is 3. What is the coefficient of the squared term
Blizzard [7]
\bf ~~~~~~\textit{parabola vertex form}
\\\\
\begin{array}{llll}
\boxed{y=a(x- h)^2+ k}\\\\
x=a(y- k)^2+ h
\end{array}
\qquad\qquad
vertex~~(\stackrel{2}{ h},\stackrel{-4}{ k})\\\\
-------------------------------\\\\
\underline{y}=a(\underline{x}-2)^2-4
\\\\\\
\textit{we also know that }
\begin{cases}
y=-1\\
x=3
\end{cases}\implies \underline{-1}=a(\underline{3}-2)^2-4
\\\\\\
3=a(1)^2\implies 3=a

A bag contains white marbles and green marbles, 52 in total. The number of white marbles is 3 less than 4 times the number of gr
valentina_108 [34]

Answer:

Step-by-step explanation:

w + g = 52

w = 4g - 3

(4g - 3) + g = 52

5g - 3 = 52

5g = 52 + 3

5g = 55

g = 55/5

g = 11....there are 11 green marbles

w + g = 52

w + 11 = 52

w = 52 - 11

w = 41 <=== there are 41 white marbles
