It is given that y is directly proportional to x. When x = 3, y = 18. (a) Find the equation connecting x and y. (b) Hence, find

guapka [62]

Answer:

see explanation

Step-by-step explanation:

(a)

Given y is directly proportional to x then the equation relating them is

y = kx ← k is the constant of proportion

To find k use the condition when x = 3, y = 18 , then

18 = 3k ( divide both sides by 3 )

6 = k

y = 6x ← equation of proportion

(b)

(i)

when x = 12 , then

y = 6 × 12 = 72

(ii)

when y = 42

42 = 6x ( divide both sides by 6 )

7 = x

Answer:

$y = -x+8$

Step-by-step explanation:

The side that is parallel to BC is EF

Find the slope of EF:

$m = \frac{2-4}{6-4} =\frac{-2}{-2} =-1$

Easiest way is just put the formula in point-slope form and simplify.

Let's use point F, which is (6,2)

$y -2=-(x-6)$

Simplify:

$y-2=-x+6$

Add 2 on both sides:

$y = -x+8$

Hope this helped
