If you have the pre-image point A(-4,1), what is the coordinates of point A" after the composite transformation rotation +90 deg
Mamont248 [21]

Answer:

(4,1)

Step-by-step explanation

1. A (-4,1)-> Original

2. I am going to assume it is 90 degrees counterclockwise since it is not specified. The formula is (-y,x)-> (-1,-4)

3. The formula is (-y,-x)-> (4,1)

I think it is (4,1) but I am not a hundred percent sure since I am also a geometry student.

The perimeter of a rectangular herb garden is 74 feet. If the length is 5 feet longer then 3 times it’s width what is the garden
NemiM [27]

Answer:

width = 8 feet and length = 29 feet

Step-by-step explanation:

perimeter of a rectangle P = 2(L + W)

width W = x

length L = 3x + 5

P = 74 feet

74 = 2(3x + 5 + x)

37 = 3x + 5 + x

37 = 4x + 5

4x = 37 -5

4x = 32

x = 8

W = 8 feet
