Answer:

Expression y = 20 - 3x represents the total amount of change she should receive.

Step-by-step explanation:

Given : Alexis bought x boxes of cereal for $3 each that is including tax

This can be written mathematically as 3x.

Let the total amount of change she should receive be denoted by y

The total amount she paid is $20

The whole scenario can be written as a single expression as,

3x + y = 20

As 20 includes the cost of x boxes and the change she received (y)

y = 20 - 3x

Thus, expression y = 20 - 3x represents the total amount of change she should receive.

Which of the following is the graph of y=sqr root -x-3
Elan Coil [88]

Answer:

The graph in the attached figure

see the explanation

Step-by-step explanation:

we have

y=\sqrt{-x-3}

we know that

The radicand must be greater than or equal to zero

so

(-x-3)\geq 0

solve for x

Adds 3 both sides

-x\geq 0+3

-x\geq 3

Multiply by -1 both sides

Remember that, when you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol

x\leq -3

so

The domain of the function is the interval (-∞,-3]

For x=-3 ---> the value of y=0

The range is the interval {0,∞)

therefore

The graph in the attached figure
