Step-by-step explanation:
14. Trick question, ignore the side.
Call the angle b.
34 + b + b = 180
2b = 146
b = 73
choice b
15. That's intersecting chords so the product of the segment lengths are equal:
5(22)=10 x
x = 5(22)/10 = 11
choice a
16. Intersecting tangent and secant;


Choice a
Well they are not in length
Answer:
The equation is 
The slope is m=-4
Step-by-step explanation:
we know that
The linear equation in slope intercept form is equal to

where
y is the amount left in the saving account
x is the number of weeks
m is the slope or unit rate of the linear equation
b is the y-intercept or initial value
In this problem we have
The slope is equal to
--> is negative because is a decreasing function
The y-intercept or initial value is

substitute
