A flagpole is 12 feet tall. Its shadow is 14 ft long. How far is it from the top of the
Kisachek [45]

Answer:

Step-by-step explanation:

AC = length of flagpole = 12 ft

AB = length of shadow = 14 ft

BC = length from the top of the flagpole to the end of the shadow = x ft

Use Pythagorean theorem to find the length of x,

x² = AC² + BC²

   = 12² + 14²

  = 144 + 196

  = 340

x = √340

x = 18.4 ft

What is the solution of the following system of equations ? y- 2x and= 6 , y - 4x =0
Sveta_85 [38]

Answer:

x=3 and y=12

Step-by-step explanation:

y-2x=6     equation:1

y-4x=0     equation:2

Solving equation:1 for 'y' in terms of x

y=6+2x      equation:3

Putting 'y' in equation:2 which will make the equation of the single variable

y-4x=0

6+2x-4x=0\\-2x=-6\\x=3

Putting value of 'x' in equation:3 to find 'y'

y=6+2x

y=6+2(3)\\y=6+6\\y=12

Write in point-slope form an equation of the line that passes through the given point and has the given slope. Point: (4, 8); m
Ainat [17]

Answer:

\mathsf{y-8=\cfrac{3}{4}(x-4)}

Step-by-step explanation:

Hi student, let me help you out!

<u>.. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. .. ... ... ..... ........   ......  ... ......... .... ....</u>

<u></u>

First, let's recall the point-slope form equation: ↪ \mathrm{y-y_1=m(x-x_1)}.

<u>where: </u> y₁ = y-coordinate of the point (the second coordinate), m=slope, x₁=x-coordinate (the first coordinate).

Let's stick in the values accordingly. We obtain the following: \mathrm{y-8=\cfrac{3}{4}(x-4)}, which is our point-slope form equation.

Hope this helped you out, ask in comments if any queries arise.

Best Wishes!
