Lily has $45 in her school lunch account. if she spends $2.50 each day, which graph represents lily's account balance, y, after she buys lunch for x days?

Step-by-step explanation:

Lily has $45 in her school lunch account.

Let the days she buys lunch be = x

And each lunch costs $2.50

So, the equation to know Lily's account balance 'y' will be :

OR in order,

The graph is attached below.

We can further see that $45 will go on for 18 days.

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
