Lexi has $80 to spend on an ice cream treat each week. If she spends $4 on ice cream per week, the function C(x)=80−4x

adoni [48]

Answer:

Domain $=\{1,2,3,4,5,6,7,8,9,10,11,12,,13,14,15,16,17,18,19,20\}$

In other words Domain $=\{x|x\ is\ an\ integer\ and\ 1\leq x\leq20\}$

Step-by-step explanation:

$C(x)=80-4x$

Let after $t$ weeks she has left no money.

$c(t)=0\\80-4t=0\\4t=80\\t=20$

That means she can have money for ice cream from the week 1 to week 20 and after that she will have no money.

So $x$ can be any number between $1$ and $20$

Hence Domain $=\{x|x\ is\ an\ integer\ and\ 1\leq x\leq20\}$

Two pools are being filled with water. To start, the first pool had 1850 liters of water and the second pool had 1334 liters of

prohojiy [21]

Answer:

a)Total amount of water in pool 1 after x minutes = 1850+27x

Total amount of water in pool 2 after x minutes = 1334+39x

b) an equation to show when the two pools would have the same amount of water is 1850+27x= 1334+39x

Step-by-step explanation:

First Pool :

Initial amount of water in Pool = 1850 liters

Water is being added to the first pool at a rate of 27 liters per minute.

Amount of water added after x minutes = 27x

So, Total amount of water after x minutes = 1850+27x

Second Pool:

Initial amount of water in Pool = 1334 liters

Water is being added to the first pool at a rate of 39 liters per minute.

Amount of water added after x minutes = 39x

So, Total amount of water after x minutes = 1334+39x

Now to find an equation to show when the two pools would have the same amount of water.

1850+27x= 1334+39x

1850-1334=39x-27x

516=12x

$\frac{516}{12}=x$

43 =x

Hence

a)Total amount of water in pool 1 after x minutes = 1850+27x

Total amount of water in pool 2 after x minutes = 1334+39x

b) an equation to show when the two pools would have the same amount of water is 1850+27x= 1334+39x
