Given:
Image of the ellipse
To find:
The equation of the image
Solution:
The given image is a ellipse.
Center of the ellipse = (0, 0)
x-axis points are (-3, 0) and (3, 0).
y-axis points are (2, 0) and (-2, 0).
Standard form of equation of ellipse:
where (h, k) is the center = (0,0)
a is the point on x-axis where y = 0. Hence a = 3.
b is the point on y-axis where x = 0. Hence b = 2.
Substitute this in the standard form of ellipse.
To make the denominator same multiply 1st term by 
and 2nd term by 
.
Multiply by 36 on both sides
The equation of the image is .
Answer:
x - y = 3
2x - y = 2
Step-by-step explanation:
x = 3 + y
2(3 + y) - y = 2
6 + 2y - y = 2
y = 2 - 6
y = -4
x = 3 + (-4)
x = 3 - 4
x = -1

Easy, just divide by a common factor, in this case, 12. 144/12 = 12 and 132/12 = 11
Answer is 12/11
Answer:
C
Step-by-step explanation:
Did the test got it right
Answer:
The domain is all real values
The range is all real values
Step-by-step explanation:
p = 20 - .8n
We can rewrite this as
p = -.8n +20
This is in the form y= mx+b
were -.8 is the slope and 20 is the y intercept
Plot at point at 20. The slope is -.8 = -8/10 = -4/5 Go down 4 and to the right 5 and plot another point. Then draw the line
The domain is the input values. What values can you put in for n
The domain is all real values
The range is the output values. What values do you get out for p
The range is all real values
