Answer:

y =  -\frac{1}{2}x + 10

Step-by-step explanation:

To find the equation of a line that passes through the point (8,6) and perpendicular to the equation 2x - y = 4, we will follow the steps below:

first write the equation 2x - y = 4 in a standard form

we will find the slope of our equation using this equation

2x - y = 4

y = 2x -4

comparing the above with

y = mx  + c

m = 2

m_{1}m_{2} = -1  ( slope of perpendicular equations)

2m_{2} = -1

m_{2}  = -1/2

our slope m = -1/2

We can now go ahead and form our equation

x_{1} =8   y_{1} =6

y-y_{1} = m (x-x_{1})

y-6 = -\frac{1}{2}(x-8)

y-6 =  -\frac{1}{2}x + 4

y=  -\frac{1}{2}x+4+6

y =  -\frac{1}{2}x + 10

Marat540 [252]

Answer:

68 inches

Step-by-step explanation:

P = 2 (L + W)

P = 2(4x+5 + 4x+5)

P = 2(8x + 10)

P = 16x + 20

If x= 3

P = 16(3) + 20

P = 48 + 20

P = 68 inches
