Answer:
A) reflection of P across the x-axis is at (3, 4).
Step-by-step explanation:
The relevant transformations are ...
(x, y) ⇒ (x, -y) . . . . . . reflection across the x-axis
(x, y) ⇒ (-x, y) . . . . . . reflection across the y-axis
__
A) sign of y-coordinate has changed: reflection across the x-axis
B) signs of both coordinates have changed: reflection across both axes
C) sign of x-coordinate has changed: reflection across the y-axis
D) sign of y-coordinate has changed: reflection across the x-axis
The only answer choice that has a proper description is Choice A.

Hope This Helps :)
You will need 90 boxes because 1252 divided by 14 equals 89.428 and you need to round up so you get 90
Answer:
maximum 5 CDs
Step-by-step explanation:
Let Mitchell can order a maximum of x CDs
It has been given that each CD costs $15.99, and shipping for the entire order is $9.99.
Thus, we have the total cost for x CDs
Now, Mitchell has no more than $100 to spend. It means
Subtract 9.99 to both sides
Divide both sides by 15.99
Hence, Mitchell can order maximum 5 CDs
This question is asking only for the slope of the regression equation. This slope can be easily calculated using the following rule:
slope = SP / SSx
Examining the givens, we will find that both parameters are given where:
SP = 30 and SSx = 10
Substituting with the givens in the above mentioned equations, we can calculate the slope as follows:
slope = 30 / 10 = 3
