Answer: x = 6

Step-by-step explanation:

X - (-4) = 10

Answer:

x = 6

Step-by-step explanation:

x-(-4) = 10

Subtracting a negative is like adding

x+4 = 10

Subtract 4 from each side

x+4-4 = 10-4

x = 6

harina [27]

Answer:

The maximum variance is 250.

Step-by-step explanation:

Consider the provided function.

V(x)=1000x(1-x)

V(x)=1000x-1000x^2

Differentiate the above function as shown:

V'(x)=1000-2000x

The double derivative of the provided function is:

V''(x)=-2000

To find maximum variance set first derivative equal to 0.

1000-2000x=0

x=\frac{1}{2}

The double derivative of the function at x=\frac{1}{2} is less than 0.

Therefore, x=\frac{1}{2} is a point of maximum.

Thus the maximum variance is:

V(x)=1000(\frac{1}{2})-1000{\frac{1}{2}}^2

V(x)=250

Hence, the maximum variance is 250.

Find the equation of the line given the slope and the y-intercept
GREYUIT [131]

Answer:

y = \frac{1}{2}x + 3

Step-by-step explanation:

The equation for a linear graph is usually written in the following format...

y = mx + b

Where m would be the slope, usually referring to rise over run and b would be the y-intercept (where the line crosses the y-axis). From the graph, we can see that the line crosses the y-axis at point 3 so b would be 3. The graph also shows us that for every 1 value that the line rises it moves to the right 2 values. Therefore, the slope would be 1/2. Using these values we can create the following equation...

y = \frac{1}{2}x + 3

(60y – 18) = 2(8-16)​
Alekssandra [29.7K]

Answer:

3/10

Step-by-step explanation:

(60y-18)=2(8-16)

60y-18=16-16

60y-18=0

60y=18 /:60

y= 18/60=3/10

Please Help! One Question!
TiliK225 [7]
Here we don't know the length of the hypo, but do have measures of both legs of this right triangle:  x and 40 yd.

  Use the tangent function to determine the value of x:

  x
--------- = tan 62 degrees.  Solving for x:    x = (40 yd)(tan 62 deg).  
40 yd                                  can you evaluate this yourself?

Which fraction equals a repeating decimal
bezimeni [28]
Here are some Examples: :) 

\frac{2}{9} is 0.2222222222 and so on

\frac{4}{9} is 0.4444444444 and so on

\frac{7}{9} is 0.777777777 and so on

So it could be anything like 9 or 6 as long is its like this  \frac{9}{4}
