Solve for x (Show work)
34kurt

Answer:

x \approx 36.57

Step-by-step explanation:

Let the length of the perpendicular be y units.

So,. By Pythagoras Theorem:

{y}^{2}  =  {32}^{2}  -  {28}^{2}  \\    = (32 + 28)(32 - 28) \\  = 60(4) \\   {y}^{2} = 240 \\  \\ by \: geometric \: mean \: property \\  {y}^{2}  = 28(x - 28) \\  240 = 28x - 784 \\ 240 + 784 = 28x \\  1024 = 28x \\  x =  \frac{1024}{28}  \\  x = 36.5714286 \\ x \approx 36.57

Help! Write the equation of the line parallel to the given line that passes through the given point in slope intercept form! *ig
Kay [80]

First let's get the equation 2x - y = -4 into slope intercept form. To do this first subtract 2x to both sides:

2x - 2x - y = -4 - 2x

0 - y = -4 - 2x

-y = -4 - 2x

Y still isn't completely isolated, it still has the negative attached to it. To get rid of the negative divide both sides by -1

-y / -1 = (-4 - 2x) / -1

y = 4 + 2x

y = 2x + 4

slope intercept formula is:

y = mx + b

m is the slope

b is the y-intercept

For a line that is parallel to y = 2x + 4 and passes through point (2, 5) you will need to have the same slope (2)

This is the formula we know so far for the line parallel to y = 2x + 4:

y = 2x + b

Now we must find b

To do that you must plug in the point the line goes through  ( 2, 5) in the x and y of the equation.

5 = 2(2) + b

5 = 4 + b

Now solve for b by subtracting 4 to both sides

1 = b

y = 2x + 1

^^^This line is parallel to 2x - y = -4 and goes through the point (2, 5)

Hope this helped!

2/3x - 7 = 1/4 What is x?
EleoNora [17]

Answer:

87/8

Step-by-step explanation:

2/3x-7=1/4

2x/3-7=1/4

2x/3=1/4+7

2x/3=29/4

2x= 29/4×3

2x=29×3/4

2x=87/4

x=87/4/2

x=87/4×2

x=87/8
