the equation framed in the form of y=kx is
and , x as a function of y
.
<u>Step-by-step explanation:</u>
Here we have , The amount Lin's sister earns at her part-time job is proportional to the number of hours she works. She earns $9.60 per hour. We need to find an equation in the form y=kx to describe this situation, where x represents the hours she works and y represents the dollars she earns.Is y a function of x . Also , Write an equation describing x as a function of y . Let's find out:
Here , Lin's sister earns $9.60 per hour . Let x represents the hours she works and y represents the dollars she earns . So , According to question following is the equation framed in the form of y=kx :
⇒ 
Yes, y is a function of x , as a straight line with a slope of 9.6
Now , x as a function of y :
⇒ 
⇒ 
Therefore , the equation framed in the form of y=kx is
and , x as a function of y
.
Answer:
9
Step-by-step explanation:
3n(n representa number of time)+2n =50
50÷2=25( shoveling side walk)
25÷3= 8.3333333333(mowling)
25+8.3333333333=33.3333333333
last year:
2n+ 3n=45
45÷5=9 ( divide 5 because you add 2+3)
shoveling once=9
