Given that the line is x/3 + y/2 =1<br> i ) make y the subject<br> ii ) gradient of line
miss Akunina [59]

Answer:

see explanation

Step-by-step explanation:

(i)

\frac{x}{3} + \frac{y}{2} = 1 ( multiply through by 6 to clear the fractions )

2x + 3y = 6 ( subtract 2x from both sides )

3y = - 2x + 6 ( divide through by 3 )

y = - \frac{2}{3} x + 2

(ii)

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope ( gradient ) and c the y- intercept )

y = - \frac{2}{3} x + 2 ← is in slope- intercept form ( that is part (i)

with gradient m = - \frac{2}{3}

Answer:

The value of <em>x</em> is 0.624.

Property used: Symmetric property of equality

Step-by-step explanation:

The expression to be solved is:

f (x) = 2.5\cdot (6.25x+0.5)-11

Compute the solution as follows:

f (x) = 2.5\cdot (6.25x+0.5)-11

       =(2.5\times 6.25\ x)+(2.5\times 0.5)-11

∵ Distributive property (a (b + c) = ab + ac)

       =15.625x+1.25-11\\=15.625x-9.75

Substitute equation equal to 0 to compute the value of <em>x</em> as follows:

0=15.625x-9.75\\\\15.625x=9.75\\\\

∵ Symmetric property of equality if a = b then b = a

x=\frac{9.75}{15.625}\\\\x=0.624

Thus, the value of <em>x</em> is 0.624.
