What is the vertex of g(x) = -3x2 + 18x + 2?<br> (3, -25)<br> (-3, -25)<br> O (3, 29)<br> (-3, 29)

Amanda [17]

Answer:

(3,29)

Step-by-step explanation:

=-3(x2-6x)+2

=-3(x2-6x+9)+2+27

=-3(x-3)2+29,so the vertex will be (3,29)

What is the system of inequalities associated with the following graph?

slamgirl [31]

One line passes through the points (-2,3) and (0,-3) , it means the y intercept is b=-3

and slope m = $\frac{(-3-3)}{0-(-2)}$

$= \frac{-6}{2}= -3$

So the equation of line will be $y= -3x -3$

And the inequality should be $y\geq -3x-3$

Or $3x +y \geq -3$

And the other line passes through (-2,3) and (0,2)

So the y intercept is b=2

and the slope is $m= \frac{2-3}{0-(-2)} = \frac{-1}{2}$

So the equation of line will be $y= \frac{-1}{2} x +2\\and the inequality should be y \leq \frac{-1}{2} x+2$

$2y +x \leq 4$

So answer is $3x +y \geq -3, x+2y\leq 4$

What is the value of the problem below?

Hitman42 [59]

Answer:

Step-by-step explanation:

The first term = 6* 2^0 = 6

The second term = 6 * 2^ (2-1) = 6*2 = 12

The third term = 6* 2^(3-1) = 6*2^2 = 6*4 = 24

The fourth term = 6* 2^(4-1) = 6* 2^3 = 6*8 = 48

S4 is the sum of the 1st four terms

S4 = 6+ 12+24+ 48 = 90
