What number is 24% of 80

Answers

Hi

24% of 80 is 19.2

100% ⇒ 80
24% ⇒ x 

100x = 24·(80)
100x = 1920
x = 1920/100
x = 19.2

Step-by-step explanation:

The linear functions f(x) and g(x) are represented on the graph, where g(x) is a transformation of f(x):

A graph with two linear functions; f of x passes through 5, 0 and 10, 10, and g of x passes through negative 3, 0 and 2, 10.

Part A: Describe two types of transformations that can be used to transform f(x) to g(x). (2 points)

Part B: Solve for k in each type of transformation. (4 points)
