tatiyna

Answer:

C. 9

Step-by-step explanation:

Ron is five years older than twice his cousin's age. Lets assume that Pat's age is 'x' years.

So Ron's age is $2\times x+5=2x+5$

The question says:

$x+2x+5$

$3x+5$

$3x$

$x$

Pat's age $(x)$ should be less than 10. Therefore, the greatest age (in integer) that Pat can be is 9 years.

-0.2x^2+0.9x+0.6=y<br>What's the vertex form for this equation?

hjlf

Answer: y = -0.2(x - 2.25)² + 1.6125

<u>Step-by-step explanation:</u>

$y = -0.2x^2 + 0.9x + 0.6\\\\y - 0.6 = -0.2x^2 + 0.9x\\\\y - 0.6 =-0.2(x^2-4.5x)\\\\y-0.6+\underline{(-0.2)(2.25)^2}=-0.2(x^2-4.5x+\underline{2.25^2})\\\\y-0.6-1.0125=-0.2(x-2.25)^2\\\\y-1.6125=-0.2(x-2.25)^2\\\\y=-0.2(x-2.25)^2+1.6125$
