Answer:
A.This is the graph of the greatest integer function
E. f(-3.4)=-4
Step-by-step explanation:
The graph shown in the attachment is the parent greatest integer function.
f(x)=[x]
This takes any integer as an input and the output is the greatest integer less than the input.
For instance
f(4.9)=4 because 4 is the greatest integer less than 4.9
f(-3.4)=-4 because -4 is the greatest integer less than -3.4
This graph is not one-to-one because more x-values can correspond to one y-value.
For instance f(3.4)=3 and f(3.9)=3
The correct options are A and E
Answer: 10xy-12+15x-8y=(5x-4)*(2y+3).
Step-by-step explanation:
N = nickels and q = quarters
0.05n + 0.25q = 1.90
n = 2q + 3
0.05(2q + 3) + 0.25q = 1.90
0.10q + 0.15 + 0.25q = 1.90
0.10q + 0.25q = 1.90 - 0.15
0.35q = 1.75
q = 1.75/0.35
q = 5 ......there are 5 quarters
n = 2q + 3
n = 2(5) + 3
n = 10 + 3
n = 13 <=== there are 13 nickels
