james is 72 inches tall. if his brother is only 80% of his height, how tall is his
inches

57.6 inches

Step-by-step explanation:

Brother=80% of James height

Where "of"= "×" and James height is 72 inches

Brother=80/100 × 72

Brother's height=4/5 ×72

Brother's height= 4*72/5

Brother's height=288/5

Brother's height= 57.6 inches

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
