Answer:

-142

Step-by-step explanation:

So we have the function:

f(x)=-x^2-9x+20

To find f(9), substitute x for 9:

f(9)=-(9)^2-9(9)+20

Square the first term and multiply the second:

f(9)=-81-81+20

Add:

f(9)=-142

And that's our answer :)

vladimir1956 [14]

Answer:

Yes, there is one outlier (lower)

Step-by-step explanation:

Looking at the distribution of the lower/smallest observation, we can see that there is a values in the lower/smallest that is very far from others. See the attached box-plot for understanding.

The median is the line in the middle of the box-plot.

The Lower fourth is the lower whisker line and upper fourth is the upper whisker line. The lower box  (just below the median) line is the 1st quartile and the upper box line (just above the median) is 3rd quartile.

If y varies directly with x, Write an equation relating x and y when y = -30 and x = 6.
ziro4ka [17]

Answer:

y=-5x

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx

so

For x=6,y=-30

substitute

y/x=k------> k=-30/6=-5

therefore

y=-5x

Can Anyone help me with this question plz ?
enot [183]
Hey!


<em>PLEASE REFER TO THE IMAGE I PROVIDED</em>

Now let's see, I graphed the points from the table you provided. The purple dots are those points.

Next, I graphed each equation to see which lined up with the points. So, you'll see that the line is graphed is y = | x | - 5.

<em>So, the equation represented by the table is</em>  y = | x | - 5.

Hope this helps!
