So, these are actually pretty simple once you learn the equality used to solve for "x" and when to implement this method. You can use this equality to solve for a segment "x" anytime that two secant lines cutting through a circle come from the same point outside the circle.
Secant: by geometric definition is just a straight line that cuts a curve into multiple pieces.
I did one of them for you hopefully you can use my work for "a" to help you solve for "b".
For a. I got x=7.
Answer: A(y=x/2)
Direct variation describes the relationship between the two variables
Good luck, i’m not sure what this is but like my comment and i’ll come back to it when i get my notes
<span>the customer needs 160 cupcakes and Cheryl already has 16 cupcakes made
</span>so she needs to make 160- 16=144 cupcakes more
if in 1 hour she can make 48
1 hour ------------------------- 48 cupcakes??? hours ---------------------144 cupcakes
cross multiplication 144divided by 48 = 3 hours
