Sav [38]

1 → B

multiply each term in the parenthesis by the 6 outside

6(b-7) = 6b - 42

2 → D

multiply each term in the parenthesis by the 3 outside

3(4x+6y+2) = 12x+18y+6

3 → A

the value outside the parenthesis is -1, hence each term inside is multiplied by -1

-1(6x+5y) = -6x -5y

The values of x and y are directly and one pair of values are given.

Anestetic [448]

Answer:

The relation is $y = -1.5x$

Step-by-step explanation:

x and y are directly proportional:

This means that the equation is given by:

$y = ax$

In which a is the multiplier that relates these two variables.

x= -4, y =6

We use this to find a. So

$y = ax$

$6 = -4a$

$a = -frac{6}{4}$

$a = -1.5$

So

The relation is $y = -1.5x$
