Y=mx+b
since the variable that will increase or deacrease is the number of books
then we set it to x
x=number of books
the member fee is constant so
b=10
the amount of money will increase by 5.99 per book so
m=5.99
the total amount of money will be our function since it depends on x
y=total amount of money
y=5.99x+10
total amount of money=5.99(number of books)+membership fee
4b+24=7b-8
32=3b
b=32/3
hope this helps!
Answer:
C. quarts
Step-by-step explanation:
Answer:
x = 40 in
Step-by-step explanation:
the missing angle in the triangle on the left is
180° - (74 + 51)° = 180° - 125° = 55°
the missing angle in the triangle on the right is
180° - (74 + 55)° = 180° - 129° = 51°
the 2 triangles have 3 pairs of congruent angles and are therefore congruent.
Corresponding sides and angles are then congruent
consider the corresponding sides opposite 74° , that is x and 40 in , so
x = 40 in
Note, since both factors have the same denominator, we can add the numerators together.
Numerator :
5n + (2m + 4n) = 5n + 2m + 4n = 9n + 2m
Denominator :
30m
Thus,
= (9n + 2m) / 30m
