If h= 1/2mk ,express m in terms of h and k
Sergeeva-Olga [200]

we are given

h=\frac{1}{2}mk

Since, we have to solve for m

so, we will isolate m on anyone side

step-1: Multiply both sides by 2

2*h=2*\frac{1}{2}mk

2h=mk

step-2: Divide both sides by k

\frac{2h}{k} =\frac{mk}{k}

\frac{2h}{k} =m

so, we get

m=\frac{2h}{k}..............Answer

Point a (–4,1) is in the standard ( x , y ) co ordinate pl an
ser-zykov [4K]
The line x = 2 is vertical. This means that ab is horizontal since they are perpendicular. So, the y coordinate of b must be 1.

If x = 2 bisects ab, then a and b are equal distances from x = 2. 

a is 2 - (-4) = 6 units away from x = 2, so b must be 6 units away in the other direction. The x coordinate of b is 6 + 2 = 8.

The coordinate of b is (8, 1)
