Answer:

The domain and range of this relationship is (-∞,∞) and (-∞,∞) respectively.

Step-by-step explanation:

We are given that Carly is traveling to visit family.

She drive distance on first day = x

She drive distance on second day = y

We are also given that Carly is travelling a total of 800 miles.

So,x+y=800

We are supposed to find domain and range of this relationship.

y=800-x

Domain : (-∞,∞)

Range:(-∞,∞)

Hence the domain and range of this relationship is (-∞,∞) and (-∞,∞) respectively.

You randomly draw a marble that contains 3 blue marbles, 4 green marbles, and 5 red marbles.
Thepotemich [5.8K]

In cases like this, i.e. when you could pick every marble with the same probability, you compute the probability of picking a specific marble colour by dividing the number of favourable outcomes by the total number of outcomes.

The number of favourable outcomes is 3, because there are 3 blue marbles.

The total number of outcomes is 12, because there are 12 marbles in total.

The function f(x) = 6x + 6 represents the amount of money Kristine earns making custom t-shirts. The function g(x) = x − 1 repre
icang [17]

The profit Kristine will make from four t-shirts is $27

Step-by-step explanation:

Given that the function f(x)=6x+6 and g(x)=x-1.

To determine how much profit Kristine will make from four t-shirts is to find (f-g)(4)

Assign the function f=6x+6 in (f-g)(4)

(f-g)(4)=(6x+6-g(x))(4)

Now, assign the function g=x-1 in (f-g)(4)

(f-g)(4)=(6x+6-(x-1)(4)

Simplifying the above equation, we get,

\begin{aligned}(f-g)(4) &=(6 x+6-x+1)(4) \\&=(5 x+7)(4)\end{aligned}

Now, Substitute x=4 , we get,

\begin{aligned}(f-g)(4) &=(5(4)+7) \\&=20+7 \\&=27\end{aligned}

Thus, the value of (f-g)(4) is 27.

Hence, the profit Kristine will make from four t-shirts is $27.
