omeli [17]

Answer:

  36 ft

Step-by-step explanation:

The pole's shadow is 6 times the length of the man's shadow, so the pole is 6 times as high as the man.

  6 × 5'11" = 30'66" = 35'6" ≈ 36 ft

 find the equation of the line that is parallel to the line Y equals 3X -6 and passes through the points (1 -8). Write the equa
AlladinOne [14]
<h3>hello!</h3>

=====================================================

Parallel lines have the same slope.

So if the given line has a slope of 3, then the line parallel to it has the same slope (3)

Now, let's write the equation of the line in Point-Slope Form.

Remember, point-slope form looks like so:-

\bigstar{\underline{\boxed{\pmb{y-y1=m(x-x1)}}}

Where

y₁ is the y-coordinate of the point that the line passes through

m is the slope

x₁ is the x-coordinate of the point that the line passes through

In this case,

y₁ is equal to -8

m is equal to 3

x₁ is equal to 1

Plug in the values:

\longrightarrow\sf{y-(-8)=3(x-1)}

Simplify:

\longrightarrow\sf{y+8=3(x-1)}

and we're done!

=========================================================

<h3>note:-</h3>

Hope everything is clear; if you need any more explanation/clarification, kindly let me know, and I will comment and/or edit my answer :)

2x + 3y = 13<br> 4x - y = -2
Mama L [17]

Answer:

x=1/2. y=4

Step-by-step explanation:

4(2x+3y=13)=8x+12y=52

2(4x-y=-2)=8x-2y=-4

subtract equation one from equation two to get

14y=56 then u will divide bothe sides by 14. for x u substitute y in equation one
