Answer:

The answer to your question is a)  y = 1.5x - 6    

                                                    b)   y = -4x + 6.1

                                                    c) Point (2.2, -2.7)

Step-by-step explanation:

First line                                                Second line

P (0, -6)           Q (1, -4.5)                        R (0, 6.1)       S (1, 2.1)

m = (-4.5 + 6) / (1 - 0)                              m = (2.1 - 6.1) / (1 - 0)

m = 1.5 / 1                                                m = -4/1

m = 1.5                                                    m = -4

Line                                                         Line

  y - y1 = m(x - x1)                                   y - 6.1 = -4(x - 0)

  y + 6 = 1.5(x)                                        y - 6.1 = -4x

  y = 1.5x - 6                                           y = -4x + 6.1

Solve the system by equality

                             1.5x - 6 = -4x + 6.1

                              1.5x + 4x = 6.1 + 6

                                    5.5x = 12.1

                                         x = 12.1 / 5.5

                                         x = 2.2

Find y

                             y = 1.5(2.2) - 6

                             y = 3.3 - 6

                             y = -2.7

Point (2.2, -2.7)

1/8 + 1/4 + 3/8 + 1/2 + 5/8 + 3/4 + 7/8 =
Damm [24]

Answer:

7/2

Step-by-step explanation:

1/8 + 1/4, you must change the denominator so that they are the same.

So that would mean 1/8+ 1/8, but since the denominator for the second one was 1/4 we must multiply the top by 2. So it becomes 1/8+2/8. You then change the denominator for the rest of them like this and it becomes 1/8+2/8+3/8+4/8+6/8+7/8 which simplified equals 7/2.
