Y is directly proportional to the square root of x If y = 32 when x = 64 find,
y when x = 25

Please help

y = 20

Step-by-step explanation:

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

y = k ← k is the constant of proportion

To find k use the condition y = 32 when x = 64, then

32 = k = 8k ( divide both sides by 8 )

4 = k

y = 4 ← equation of proportion

When x = 25, then

y = 4 = 4 × 5 = 20

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
