The school canteen charges Rs 42 for lunch and Rs 8 for milk for each day. How much money do you spend in 5 days on these things? Write proper steps. State the property used.

Step-by-step explanation:

Cost of lunch for 1 day=Rs42

Cost of lunch for 5 days=Rs42×5

Cost of Milk for 1 day=Rs8

Cost of Milk for 5 days=Rs8×5

Now,

Total cost=42×5+8×5

=5×(42+8)(Taking 5 common)

=5×50

=250

Thus,Total money spent is Rs250

I hope it's helpful!!

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8
