2. Make P the subject of the formula y = a + p/a-p A. 2a - y/a + y B. ay-1/y+1 C. a(y-1)/y+1 D. 2y-1/y-1

a(y-1)/1+y

Step-by-step explanation:

Given the expression y = a + p/a-p

yo are to make P the subject of the formula:

Step 1:  Cross multiply

y = a + p/a-p

y(a-p) = a+p

Step 2: open the bracket

ya - yp = a+ p

Step 3: Collect the like terms

ya - a  = p+ yp

ya - a= p(1+y)

a(y-1) = p(1+y)

Step 4: Divide both sides by 1+y

a(y-1)/1+y = p(1+y)/1+y

a(y-1)/1+y = p

p =a(y-1)/1+y

Hence the required solution is p = a(y-1)/1+y

step-by-step explanation:

the system of inequalities is

step-by-step explanation:

step 1

find the equation of the dashed line

we have the points

(0,0) and (3,1)

the line passes through the origin, so, is a direct variation

find the slope

the equation of the dashed line is

the solution of the inequality a s the shaded area above the dashed line

therefore

the equation of the inequality a is

step 2

find the equation of the solid line

we have the points

(4,0) and (0,4)

find the slope

the equation of the solid line is

the solution of the inequality b s the shaded area below the solid line

therefore

the equation of the inequality b is

step 3

the system of inequalities is
