A) Every T is worth 7 points, and every F is worth 3 points. So if we let T = 7 and F = 3, we can count how many T's and F's each team scored and write it as an expression.

So for the East Side Bulldogs, they have 7 touchdowns and 6 field goals, thus the expression for them is:

7T + 6F

For the West Side Bulldogs, they have 5 touchdowns and 5 field goals, thus the expression for them is:

5T + 5F

B) The difference would be written as:
7T + 6F - (5T + 5F) = 2T + F

C) To determine how many more points the winning team has than the losing team, calculate the scores of the two teams. Then subtract the smaller number from the larger number to determine the score differential.

An online music service that sells song downloads models it's profit using the function P(d)=-5d^2+450d-1000, where d is the num

NeTakaya

Answer:

Step-by-step explanation:

P(d) ≥ 8000

P(d) = - 5d^2 + 450d - 1000 ≥ 8000 Subtract 8000 from both sides

-5d^2 + 450d - 1000 - 8000 ≥ 0 Combine like terms

-5d^2 + 450d - 9000 ≥ 0 Divide through by - 5

d^2 - 90d + 1800 ≥ 0 Factor

(d - 60)(d - 30)

So d ≥ 60

or d ≥ 30

So if customers make more than 30 downloads, the profit goes up 8000.

Segmentul AD contine punctele B si C astfel incat AB = 4cm, AC = 12cm, AD = 20cm. Aratati ca punctul C este mijlocul segmentului

kramer

Step-by-step explanation:

If segment AD contains point B and, then A, B, C and D lies on the same straight line as shown in the attachment.

To show that point C is the middle of point BD, we musr show that segment BC is equal to CD i.e BC = CD.

From the diagram, AC = AB+BC

Given AC = 12cm and AB = 4cm

BC = AC-AB

BC = 12cm - 4cm

BC = 8cm

Also AD = AB+BC+CD

Given AD = 20cm, AB = 4cm and BC = 8cm

CD = AD-(AB+BC)

CD = 20-(4+8)

CD = 20-12

CD = 8cm

It can be seen that BC = CD = 8cm, hence C is the midpoint of B and C.
