Answer:
60
Step-by-step explanation:
Given: 60% out of 100
Expressed mathematically:
= (60/100) x 100
= 60
That's not a function.
Since a vertical line hits the graph more than once, if fails the test. (See graph below)
If it is a function, any vertical line you draw can only hit the graph once.
Answer:
x-y=5
Step-by-step explanation:
If a line has a slope of 1, its function can be write as x-y=c
insert point (7,2),t then we can find out the constant c=5, so the equation of this line is x-y=5
Answer:
14/61 cm per day
Step-by-step explanation:
Use the slope formula 
Plug it in 
Simplify 
Example
from pir^2 ro pi(2r)^2
pi(2r)^2=pi4r^2=4pir^2
basicaly we look for any no options and ones where second is 4 times first
B
pi2^2, if it is double, pi4^2
B
