Novosadov [1.4K]

Answer:

(d)  y= (1 1/9)x

Step-by-step explanation:

A proportional relation is described by the equation ...

 y = kx

Dividing by x shows how to find the value of k:

 k = y/x

For the given values of y and x, the value of k is found to be ...

 k = (5/6)/(3/4) = (5/6)(4/3) = 20/18 = 10/9 = 1 1/9

The relationship is represented by the equation ...

8*{[7+4)*2-[(11-7)*4]}
Rzqust [24]

Answer:

(8 (-1))

Step-by-step explanation:

Simplify the following:

8 (7 + 4×2 - 4 (11 - 7))

11 - 7 = 4:

8 (7 + 4×2 - 44)

4×2 = 8:

8 (7 + 8 - 4×4)

-4×4 = -16:

8 (7 + 8 + -16)

7 + 8 = 15:

8 (15 - 16)

15 - 16 = -(16 - 15):

8 (-(16 - 15))

| 1 | 6

- | 1 | 5

| 0 | 1:

8 (-1)

8 (-1) = (8 (-1)):

Answer: (8 (-1))
