Answer:
B
Step-by-step explanation:
The domain is the set of x values for which the function is defined.
The range is the set of y values for which the function is defined.
Attached is the graph of the exponential function.
It is the basic graph of exponential function of y = 5^x which is shifted 6 units above (because of +6 at the end).
<em><u>Looking at the graph, the domain is the set of all x values.</u></em>
<em><u>The range is anything above 6.</u></em>
Correct answer is B.

Answer:
(2,-3)
Step-by-step explanation:
I am not sure if you meant the first equation to be y or -y. I solved it as y.
y = x-5 -x -3y =7
I am going to take the second equation and write it as x =
-x - 3y = 7 Give equation
-x = 3y +7 Add 3y to both sides
x = -3y-7 Multiplied each term in the equation by -1 so that x could be positive
I am going to substitute -3y-7 for x in the first equation up above
y = x - 5
y = -3y -7 - 5 Substitute -3y-7 for x
y = -3y -12 Combined -7-5
4y = -12 Added 3y to both sides
y = -3 Divided both sides by 4.
I now know that y is -3, I will plug that into x = -3y-7 to solve for x
x = -3(-3) -7
x = 9-7 A negative times a negative is a positive
x = 2
