x = 109°
3*180° - 100° - 102° - 108° - 121° = 109°
Answer :
Letter C : e = 40,000 + 200 x c
If the two quadrilateral are congruent, then ABCD = PQRS is the correct congruence statement.
For #7 - part a: greatest common factor (GCF) is 5.
Part b: cross out everything BUT 10 & 20.
Answer:
C. $25
Step-by-step explanation:
We will find,
The slope of the function using
.
Taking the points (1,40) and (2,55).
Slope = 
i.e. Slope = 
i.e. Slope = 15
Substituting the slope and point (1,40) in the equation
,
We have, 
i.e. 
i.e. b= 25
Thus, the equation of the linear function is
.
<em>This linear function represents the cost of the comic book since Lucy purchased it, where x= years.</em>
So, the initial value of the comic book is when x= 0.
So,
i.e. y= 25
Hence, the cost of the book when Lucy purchased it was $25.
