D, because of the arrows going both directions, you know part of it,
( -  \infty \:  x) \: ( x  \:  \infty )
and then you just have to put in the values from the number line. The first arrow ends at zero with a bracket, and brackets mean the number is included. So now you have,

( - infinity, 0] ( x, infinity)

Then, your last value is at 1/2 with a parentheses, indicating it is not included. So, your final answer would be,

( - infinity, 0] ( 1/2 , infinity)

{infinity is always written with a parentheses in domain}

K(x) = 6x+100 k(-5) =
kkurt [141]

Answer:

k(-5)=70

Step-by-step explanation:

The given function is

k(x)=6x+100

To find k(-5), we put x=-5 into the given function to get;

k(-5)=6(-5)+100

Multiply out to obtain;

k(-5)=-30+100

This is the same as;

k(-5)=100-30

This simplifies to

k(-5)=70

Answer:

The price of hot dog is $2.5 and that of a pretzel is $1.25.

Step-by-step explanation:

Let the cost of hotdogs be x and that of pretzels be x.

So,

4x+3y = 13.75 ...(1)

and

2x+5y = 11.25 ...(2)

Multiply equation (2) by 2.

4x+10y = 22.5 ...(3)

Subtract equation (1) from (3).

4x+10y-(4x+3y) = 22.5-13.75

4x+10y-4x-3y = 8.75

7y = 8.75

y = 1.25

Put the value of y in equation (1).

4x+3(1.25) = 13.75

4x+3.75 = 13.75

4x = 13.75-3.75

4x = 10

x = 2.5

So, the price of hot dog is $2.5 and that of a pretzel is $1.25.
