Which of the following is the domain and range of the ellipse with equation 4x2 + 25y2 – 8x + 100y + 4 = 0?
Likurg_2 [28]

The domain of the ellipse is [-4. 6] and the range of the ellipse is [-4. 0]

<h3>How to determine the domain and the range of the ellipse?</h3>

The equation of the ellipse is given as:

4x^2 + 25y^2 – 8x + 100y + 4 = 0

Next, we plot the graph of the ellipse

See attachment for the graph of the ellipse

<u>The domain</u>

From the attached graph the minimum and the maximum values of x are:

Minimum = -4

Maximum = 6

So, the domain of the ellipse is [-4. 6]

<u>The range</u>

From the attached graph the minimum and the maximum values of y are:

Minimum = -4

Maximum = 0

So, the range of the ellipse is [-4. 0]

Hence the domain of the ellipse is [-4. 6] and the range of the ellipse is [-4. 0]

56of the 90pets in the pet show are cats 4/5of the cats are calico cats. What fraction of the pets are calico cats?
meriva
To get the answer, we can divide 56 by 5 to find one fifth of the cats. Then, we can multiply this number to get four fifths of the cats. Then, we put this number over 90 since there is 90 pets in the entire show. Then, this answer ends up being about half all of the pets are calicos.

y=-3x+4

x=2y+6

y + 3x =4

-2 + =6

x= 2y +6

y+3.(2y+6)=4

7y = -14

7y=-14

y=-2

y=-2

x=2y+6

x=2(-2)+6=2

solution is {y,x}= {-2,2}
