Answer:

y = ¼(x-4)

Step-by-step explanation:

Before solving the question, let's look at one example,

  • A is directly proportional to B means A∝B which also means A=kB where k is a constant.

In this case, y is directly proportional to (x-4) means that y∝(x-4) which can also mean that y=k(x-4).

Hence, to find the value of k, substitute x=16, y=3 into y=k(x-4),

3=k(16-4)

k=3/12

k=1/4

After that, substitute the k value into the equation,

<h3>y = ¼(x-4)</h3>

Answer:

(3, 2) is the ordered pair for the given system of equations.

Step-by-step explanation:

Given:

2 x+ y = 8.......................(i)

y = - x + 5........................(ii)

<u>Put y = - x + 5 in equation (i)-</u>

<em>2 x + ( - x+ 5) = 8</em>

<em>2 x - x + 5 = 8</em>

<em>x = 8 - 5</em>

<em>x = 3</em>

<u>Now put x = 3 in equation (ii)-</u>

<em>y = - 3 + 5</em>

<em>y = 2</em>

Hence the (3, 2) is the correct ordered pair.
