When a car ends up 0 m from its starting point.....this means that the distance driven is the same distance when coming back
The car first travels a distance of 9 meters, and then travels 9 meters in the opposite direction <=== 9 - 9 = 0
When the x-value has increased by 1 unit, the y-value has multiplied by 3, so we expect a function of the form (something)×(3^x). The last choice has that.
... f(x) = 4(3)^x
_____
You can always evaluate the offered choices at the given points to see which of them works. The second point (2, 36) will tell you the fastest.
4·3^-2 = 4/9 ≠ 36 . . . . . you can tell at this point you don't want -x as the exponent
3·4^-2 = 3/16 ≠ 36
3·4^2 = 48 ≠ 36
4·3^2 = 36 = 36 . . . . this is the one you want

Answer:
112.5 square feet
Step-by-step explanation:
The scale model is 6 x 3 and the actual patio is 15 x W
By the definition of a scale model,
15/6 = W/3
15 = 2W multiply both sides by 6
15/2 = W divide both sides by 2
Area of the patio = length * width
Area = 15 feet * 15/2 feet = 225/2 square feet = 112.5 square feet
Answer:
5.25 or 5 1/4
Step-by-step explanation:
2 5/8 x 2 = 5 1/4
