Answer:
x = $2.56
Step-by-step explanation:
To solve this, you do the inverse of both operations, which is multiplication and subtraction. The first inverse would be addition, so 2.81 + 2.31 = 5.12. Then, the second inverse would be division, so 5.12 divided by 2 = 2.56. So therefore, x = $2.56 is the correct answer for the price in September 2006.
If I understand your question well, I suppose you mean
Answer:
A
Step-by-step explanation:
The angle adjacent to 133 and 133 form a straight angle and are supplementary, hence
adjacent angle = 180° - 133° = 47°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles. The angle 90 is an exterior angle, thus
p + 47 = 90 ( subtract 47 from both sides )
p = 43° → A
The ratio of coordinates in the image to the coordinates of the original will tell you the dilation factor when diation is about the origin (as here).
Jx'/Jx = -2/-3 = 2/3
This same ratio is true for the other 5 coordinate values, so we know that ...
... the scale factor used in the dilation is 2/3.
_____
Jy'/Jy = -8/-12 = 2/3
Kx'/Kx = -4/-6 = 2/3
Ky'/Ky = -10/-15 = 2/3
Lx'/Lx = -6/-9 = 2/3
Ly'/Ly = -8/-12 = 2/3
