Answer:

$y = 69$

Step-by-step explanation:

Given the following question:

$y=2x+9x+3$
$x=6$

Substitute and solve using PEMDAS:

$y=2x+9x+3$
$y=2(6)+9(6)+3$
$2\times6=12$
$y=12+9(6)+3$
$9\times6=54$
$y=12+54+3$
$12+54=66$
$66+3=69$
$y=69$

Your answer is "y = 69."

The graphs below are both quadratic functions. The equation of the red graph is

Natali5045456 [20]

Answer:

D. $g(x)=\frac{1}{5}x^2$

Step-by-step explanation:

The equation of the red quadratic graph is $f(x)=x^2$ .
This is the parent quadratic function or the base of the quadratic functions.
This red quadratic graph has been dilated by a certain scale factor to obtain the blue graph. Recall that, when the scale factor is a fraction, such that $0\:$ the graph is stretched horizontally.
The dilated graph then becomes wider than the parent function.
From the given function equations, the possible value of k can only be $k=\frac{1}{5}$ .
Therefore the blue graph has equation: $g(x)=\frac{1}{5}x^2$
The correct answer is D.
