This seems to be a reflection over the 'y' axis. Notice that the 'x' coordinates of points U and V are x =2 in the original figure, and then, 'x' coordinates of U' and V' are x = -2
All 'y' coordinates for the transformated figure (S'T'U'V'W') are the same that the original figure (STUVW), but the 'x' coordinates are exactly the opposite
This transformation is :
Answer:
The radius of the circle is 3 units. TRUE
The center of the circle lies on the x-axis. TRUE
The center of the circle lies on the y-axis. FALSE
The standard form of the equation is (x – 1)² + y² = 3. FALSE
The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9. TRUE
Step-by-step explanation:
x² + y² - 2x - 8 = 0
x² - 2x + y² = 8
Complete the square in x.
x² - 2x + 1 + y² = 9
(x - 1)² + y² = 3²
Center: (1, 0); radius: 3
The radius of the circle is 3 units. TRUE
The center of the circle lies on the x-axis. TRUE
The center of the circle lies on the y-axis. FALSE
The standard form of the equation is (x – 1)² + y² = 3. FALSE
The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9. TRUE
Answer:
x=1
Step-by-step explanation:
11x+4=3x+12
11x=3x+8
8x=8
x=1

Answer:
0.625 62.5%
Step-by-step explanation:
" break even " is when ur expenses = revenue.....there is no profit made when u break even
expenses : 0.35x + 770
revenue (ur income) : 0.55x
so they have to equal to break even...so set them equal to each other and solve for x
0.35x + 770 = 0.55x
770 = 0.55x - 0.35x
770 = 0.2x
770 / 0.2 = x
3850 = x <== they must sell 3850 copies to break even
