Answer:
Domain: All Real Numbers
Range: y<0
Step-by-step explanation:
Looking at the graph, you can tell that the variable y has a lower point.
( I'm not sure how accurate this is I'm doing the same test right now. ;-;)
We can solve this problem by using the distance formula. The distance formula is:
We can now put in values and solve.

Answer:
when we put 1 from a2 we can say that a2 equal to 2 because 2.5^n-1= 2
Step-by-step explanation:
answer is b
Answer: The y intercept is -7 or (0,-7)
Step-by-step explanation:
First convert the equation into slope intercept form .
y - 3 = -2(x + 5) Multiply on the right side
y -3 = -2x - 10 Add 3 to both sides
+3 +3
y = -2x - 7
In this case the y intercept is -7 and it is when x is zero.
Answer:
Step-by-step explanation:
We are given the following in the question:
Number of shirts bought from Walmart = n
Cost of one shirt at Walmart = $9 per shirt
Total cost of shirt at Walmart =

Number of shirts bought from Amazon = n
Cost of one shirt at Amazon = $8 per shirt
Shipping fee for entire order = $5
Total cost of shirt at Amazon =

Total amount spent by Netta on shirts in one day =
Total cost of shirt at Walmart + Total cost of shirt at Amazon

is the required expression where T(n) is the total cost and n is the number of shirts purchased at Walmart as well as Amazon.
