<u>Given Equation is:</u>

Adding 9 to both sides
=> 
=> 
Multiplying 2 to both sides
=> -3x = -18 * 2
=> -3x = -36
Dividing both sides by -3
=> x = 12

Step-by-step explanation:
The scale factor is the ratio of corresponding sides, image to original, thus
scale factor =
=
, then
x =
× 9 = 2 × 3 = 6
y =
× 7 = 
Answer:
y = 1/2x + 4

Answer:
The length of the rectangle is 50 feet, while the width of the rectangle is 10 feet.
Step-by-step explanation:
Since the length of a rectangle is 5 times the width, to determine the length of the rectangle if the area is 500 square feet, the following calculation must be performed:
Area = Base x height
500 = X x 5X
500/5 = X x X
100 = X x X
100 = 10 x 10
X = 10
Thus, the length of the rectangle is 50 feet, while the width of the rectangle is 10 feet.
