Find the slope of the line that is perpendicular to 3x+4y=20

Mathematics

Answer:

4/3

Step-by-step explanation:

First, find the slope of the given equation.  To do this, solve it for 4y, and then for y:

Subtracting 3x from both sides, we get

4y = -3x + 20, and

dividing both sides by 4 yields

y = (-3/4)x + 5.  The slope of the given line is -3/4.

The slope of any line perpendicular to this one is the negative reciprocal of -3/4, meaning it would be +4/3.

Answer:

The slope would be four thirds (4/3)

Step-by-step explanation:

3x+4y=20

-3x      -3x

4y=20-3x

divide by 4 on each side to each term

y=5-(3/4)x

you then take the opposite reciprocal the slope -3/4 to have the perpendicular slope of 4/3

The perpendicular bisector theorem gives the statements that ensures

that \overleftrightarrow{FG} and \overleftrightarrow{AB} are perpendicular.

The two statements if true that guarantee  \overleftrightarrow{FG} is perpendicular to line \overleftrightarrow{AB} are;

  • \overline{CE} = \overline{CD}
  • \overline{DF} = \overline{EF}

Reasons:

The given diagram is the construction of the line \mathbf{\overleftrightarrow{FG}} perpendicular to line \mathbf{\overleftrightarrow{AB}}.

Required:

The two statements that guarantee that  \overleftrightarrow{FG} is perpendicular to line \overleftrightarrow{AB}.

Solution:

From the point <em>C</em> arcs <em>E</em> and <em>D</em> are drawn to cross line \overleftrightarrow{AB}, therefore;

\overline{CE} = \mathbf{\overline{CD}} arcs drawn from the same radius.

\overleftrightarrow{FG} is perpendicular to line \overleftrightarrow{AB}, given.

Therefore;

\overline{DF} = \overline{EF}  by perpendicular bisector theorem.

Answer:

C. 5x + 11 = 36

Step-by-step explanation:

You can see in the diagram that there are 5 x variables and eleven which make up the total diagram that says 36 so it would have to be 5x+11 = 36

Sam decides to build a square garden. If the area of the garden is 25x2 + 30x + 9 square feet, what is the length of one side of
seropon [69]
The correct answer is C. (5x+3) feet, and here is how I got it.
This is the equation you need to use:
(a+b)^2 = (a+b) (a+b)
So, let us plug in 5x and 3 here:
(5x+3)^2 = (5x+3)(5x+3) = 25x^2 + 15x + 15x + 9 = 25x^2 + 30x + 9 which is the area of the garden.
