Answer:
Step-by-step explanation:
a.
y=0.75x
y-y1=(y2-y1)/(x2-x1)×(x-x1)
y-3=(6-3)/(8-4) (x-4)
y-3=3/4(x-4)
y-3=3/4 x-3
y=3/4 x-3+3
y=3/4 x
if y=f(x)
f(x)=0.75x
c.
f(12)=0.75×12=9$
Answer:
The charge for shovelling snow for 6 hour is 72 hours
Step-by-step explanation:
Given as :
The charge for shovelling snow for 2 hours is $30
Let The charge for shovelling snow for 6 hours = $ x
Now, Applying unitary method
∵ The charge for shovelling snow for 2 hours = $30
or, The charge for shovelling snow for hour = $30
So, The charge for shovelling snow for 1 hour = hour
∴ The charge for shovelling snow for 6 hour = × 6 hours
I.e The charge for shovelling snow for 6 hour = hours
= 72 hours
Hence The charge for shovelling snow for 6 hour is 72 hours Answer
