20,000 = 80% of the original price so 20,000 divided by 80 = 250 then multiply that by 100 equals 250000 which is the original price

Answer:
x > -1
Step-by-step explanation:
Here, we want to check for the relationship between the image and its pre-image
The pre-image is (x,y)
The image is (3x,3y+5)
As we can see, the pre-image is not similar
This is because the transformation applied to the two values are not same
Thus, we have that;
No, the image is not similar to the pre-image as the translations applied to both coordinates are not same
The pre-image was transformed by dilating the x-coordinate of the pre-image by 3 units while the y-coordinate was transformed by dilating the y-coordinate of the pre-image by 3 and translating it upward by 5 units
The correct answer is C. All reference angles must be less than 90 degrees.
This is helpful when learning more complex topics including circular trigonometry and the unit circle, because the reference angle (typically denoted as theta prime) has the same trig values (sine and cosine) no matter which quadrant the angle is located in. Additionally, the reference angle is always the smallest angle possible between the terminal side of the angle and the x-axis; therefore, it must always be less than 90 degrees or else another smaller (and thus correct) reference angle could be made in another quadrant.
Hope this helps!
