Reasoning A store sells packages of comic books with a poster. A poster and 2 comics cost $7.75. A poster and 19 comics cost $15.75. Write a linear function rule that models the cost y of a package
containing any number x of comic books.
Suppose another store sells a similar package, modeled by a linear function rule with initial value
$7.75. Use pencil and paper. Explain which store has the better deal.
The linear function rule is y=.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

answer: - (a)

(b) 88 seats

step-by-step explanation:

given: in an auditorium, there are 22 seats in the first row and 28 seats in the second row.

thus first term=

second term=

the number of seats in a row continues to increase by 6 with each additional row.

⇒d= 6

a) given formula :

b)   let the number of seats (n) = 12

substitute n=12 in the explicit rule formed in (a)

∴there are 88 seats in 12 rows.
