Triangle XYZ is rotated 90° clockwise about the origin. On a coordinate plane, triangle X Y Z has points (negative 3, 1), (4, 4), (4, 1). What are the coordinates of point X’? (1, 3) (3, –1) (3, 1) (–1, –3)

(1,3), or option 1

Step-by-step explanation:

The formula for a 90 degree clockwise rotation is (x,y)>(y,-x). In this case it started out as (-3, 1). Using the formula you get (1,-3(-1)), which is equal to (1,3). Hence option 1 is correct

1,3 or option 1

Step-by-step explanation:

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2

step-by-step explanation:

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
