Given:

The table of values.

v and x are in direct proportion.

To find:

The formula connecting v and x.

Solution:

(a)

v and x are in direct proportion.

[tex]v\propto x[/tex]

[tex]v=kx[/tex]            ...(i)

Where, k is the constant of proportionality.

Putting v=13.6 and x=32.64, we get

[tex]13.6=k(32.64)[/tex]

[tex]\dfrac{13.6}{32.64}=k[/tex]

[tex]\dfrac{5}{12}=k[/tex]

Putting the value of k in (i), we get

[tex]v=\dfrac{5}{12}x[/tex]

Therefore, the required formula that connecting v and x is [tex]v=\dfrac{5}{12}x[/tex].

(b)

Putting v=n and x=8.16, we get

[tex]n=\dfrac{5}{12}(8.16)[/tex]

[tex]n=3.4[/tex]

Therefore, the value of n is 3.4.

Find the value of a and b.
2x + 5y = 9
3x – 2y = 4
x= ?
y= ?

Answers

2x + 5y = 9
3x - 2y = 4

1) Make the x equal the same (find common factor) which is 6
2) Time the whole equation by the factor for example 2x3= 6, times the top equation by 3. The bottom 3x2=6, times the bottom equation by 2:

6x+15y=27
6x-4y=8
(Cancel the x)

Left with: 19y =19 (15- -4y =19y) (27-8=19)
Therefore y = 1

Now substitute y=1 into the equation to find x

6x + 15(1)= 27
6x + 15 = 27
6x = 12
X = 2

Answers:
X=2, Y=1
