after a reflection over the line y=x (8,11) is the image of point c. what is the original location of point c
Answers
(positive to negative/negative to positive for either the x or y)
hope this helps
The original location of point C before a reflection over the line y=x, given that the image of point C is at (8,11), would be (11,8) as coordinates are swapped during such a reflection.
Explanation:To determine the original location of point C before a reflection over the line y=x, you would apply a simple transformation rule. For any reflection over the line y=x, the coordinates of a point are swapped. Thus, if the image of point C is at (8,11), the original location of point C would have the x-coordinate as 11 and the y-coordinate as 8.
The step-by-step process to find the original location of point C before the reflection is as follows:
Take the x-coordinate of the image and make it the y-coordinate of the original point.Take the y-coordinate of the image and make it the x-coordinate of the original point.The resulting point is the original location of C before the reflection.Therefore, the original location of point C is (11, 8).
X+3/6=x-6/3
x plus 3 divided by 6 equals x minus 6 divided by 3 solve for x
Answers
_____________________________________________
Explanation:
_____________________________________________
Given:
_____________________________________________
" (x + 3) / 6 = (x − 6) / 3 " ; Solve for "x" ;
_____________________________________________
Multiply EACH SIDE of the equation by "6" ;
to get rid of the "denominators" ("fractions") :
_____________________________________________
→ 6* { (x + 3) / 6 } = 6 * { (x − 6) / 3 } ;
to get:
_____________________________________________
→ x + 3 = 2(x − 6) ;
_____________________________________________
Note the "distributive property of multiplication" :
_____________________________________________
a(b + c) = ab + ac ;
a(b − c) = ab − ac ;
_____________________________________________
As such:
_____________________________________________
→ 2(x − 6) = (2*x) − (2* 6) = 2x − 12 ;
_____________________________________________
So; we can rewrite the original equation:
_____________________________________________
" x + 3 = 2(x − 6) " ;
→ by substituting: "2x − 12" ; [ in lieu of: "2(x − 6)" ] ; as follows:
______________________________________________________
→ x + 3 = 2x − 12 ;
Now, we can subtract "x"; and can add "12" ; to EACH SIDE of the equation:
→ x + 3 − x + 12 = 2x − 12 − x + 12 ;
to get: 15 = x ;
↔ x = 15 ; which is our answer.

If the unit selling price is 2.50 and the unit cost is 1.00 what action is needed to maintain the gross margin percentage when unit cost increase 0.25
Answers
The original gross margin is (2.50 / 1.00) - 1 = (2.5 - 1) = 1.5 = 150%
the cost increases 0.25, is an increase of (0.25 / 1.00) = 25%
in order to keep the same gross margin, you need to increase the sale price by 25%
2.50*1.25 = 3.125
Then the gross margin is (3.125 / 1.25) - 1 = (2.5 - 1) = 1.5 = 150% ( same as original )

If a television screen with a length-to-height ratio of 16:9 has an area of 576in, what is it's perimeter?
Answers
Final answer:
The perimeter of the television screen is 100 inches.
Explanation:
To determine the perimeter of a television screen with a length-to-height ratio of 16:9 and an area of 576 square inches, we need to find the length and the height of the screen first.
Using the ratio, we let the length be 16x and the height be 9x.
The area of a rectangle is given by its length times its height, so we have:
(16x) × (9x) = 57
144x² = 576
x² = 576 / 144
x² = 4
x = 2
Now we can find the actual dimensions:
Length = 16 × 2 = 32 inches
Height = 9 × 2 = 18 inches
The perimeter (P) of a rectangle is given by
P = 2 × (Length + Height)
P = 2 × (32 + 18)
P = 2 × 50
P = 100 inches
The perimeter of the television screen is 100 inches.

The population of Pleasanton at the end of the 1990s is 17% higher than the population in 1980.
Explanation:To compare the population of Pleasanton in the 1990s with the population in 1980, we need to consider the changes that occurred in each decade. In the 1980s, the population decreased by 10%. This means that if the population in 1980 was represented by 100, it would have decreased to 90 by the end of the decade.
In the 1990s, the population increased by 30%. Using the population of 90 at the beginning of the decade, the population at the end of the 1990s would be 90 + (30% of 90) = 90 + 27 = 117.
So, the population of Pleasanton at the end of the 1990s is 117, which is 17% higher than the population in 1980. Therefore, the correct answer is D) It is 17% higher.

A referee was standing on a certain yard line as the 1st quarter ended. He walked 41 3/4 yards to a yard line with the same number as the one he just left. How far was the refree from the nearest goal
Answers
The American football field is 100 yds long, 53 1/3 yards wide, and has 10-yard touchdown zones at each end of the field.
Let x = distance of the referee at the end of the quarter from the nearest goal.
The distance between the same yard lines on either side of the center line is
100 - 2x
This distance is the 41 3/4 yards that the referee walked. Therefore
100 - 2x = 41.75
-2x = 41.75 - 100 = -58.25
x = 29.125 yd (or 29 1/8 yd)
Answer:
The referee was 29 1/8 yards (or 29.125 yards) from the nearest goal.
