Answer:

h=-6 k=-30

Step-by-step explanation:

y=x^2+12x+6

\mathrm{The\:vertex\:of\:an\:up-down\:facing\:parabola\:of\:the\:form}\:y=ax^2+bx+c\:\mathrm{is}\:x_v=-\frac{b}{2a}

a=1,\:b=12,\:c=6

x_v=-\frac{b}{2a}

x_v=-\frac{12}{2\cdot \:1}\\

x_v=-6\\

\mathrm{Plug\:in}\:\:x_v=-6\:\mathrm{to\:find\:the}\:y_v\:\mathrm{value}

y_v=\left(-6\right)^2+12\left(-6\right)+6\\y_v=-30\\\left(-6,\:-30\right)

A pet survey found that the ratio of dogs to cats is 2/5. Write and solve a proportion that shows the number of dogs
Irina18 [472]
So,

The ratio of dogs to cats:
\frac{2}{5}

The other proportion:
\frac{x}{140}

\frac{2}{5} =  \frac{x}{140}

5 times 28 is 140.

Multiply the fraction by the appropriate form of 1
\frac{2}{5} * \frac{28}{28} =  \frac{56}{140}

There are 56 dogs when the number of cats is 140.
