The skeeters baseball team charges $7. per ticket plus $3. processing fee for each order. is the cost of an order proportional to the number of tickets ordered? explain how you know. tickets | price 1 | 10 2 | 17 4 | 31 5 | 38 10 | 73

We are given : Per ticket cost = $7.

Processing fee of each order = $3.

Total cost of order including number of tickets costs = 3 + 7* number of tickets.

We are given table : Tickets | Price

1 | 10

2 | 17

4 | 31

5 | 38

10 | 73.

Let us rewrite that table according to the rule 3 + 7* number of tickets.

Tickets | Price

1 |  3 + 7*1 = 10

2 | 3 + 7*2 =17

4 | 3 + 7*4 = 31

5 | 3 + 7*5 = 38

10 | 3 + 7*10 = 73.

We can see that costs are proportional accoriding to the rule :

Total cost of an order =  3 + 7* number of tickets.

Let us explain it by one more way..

We can explain it by applying slope formula.

Plugging values in above formula by taking (1,10) and (2,17) coordinates form above table, we get

By taking (2,17) and (4,31) coordinates form above table, we get

We got same ratios for slope 7/1.

Therefore, we can say the cost of an order proportional to the number of tickets ordered.

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !

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
