What is the slope-intercept equation of this line?

Mathematics
1 answer:
Gekata [30.6K]3 years ago
7 0

Answer:

y = -2x+8

Step-by-step explanation:

We have 2 points so we can find the slope

m = (y2-y1)/x2-x1)

m = ( -4 -8)/(6 - 0)

    = -12/6

   = -2

The y intercept is 8 from the point (0,8)

The slope intercept form is

y = mx+b where m is the slope and b is the y intercept

y = -2x+8

Answer:

<h2><u><em>17/12</em></u></h2>

Step-by-step explanation:

x - 3/4 = 2/3

x = 2/3 + 3/4

x = 17/12

A biologist wants to know the width w of a river in order to properly set instruments for studying the pollutants in the water.
belka [17]

Answer:   The river is 148.3 feet wide.

Step-by-step explanation:

Alright, lets get started.

Please refer the diagram I have attached.

The triangle formed is a right triangle.

Using SOH CAH TOA

tan 56 = \frac{x}{100}

Multiplying 100 in both sides

x = 100 \times tan56

x = 100 \times 1.4826

x = 148.26

Rounding to the one decimal place

x = 148.3

Hence river is 148.3 feet wide.   .............. Answer

Hope it will help :)

PLEASE HELP!!! :))
Nina [5.8K]

For a better understanding of the solution given here please find the attached file which has the relevant diagram.

To answer this question we will have to make use of <u>the Isosceles Triangle Theorem</u> which states that the perpendicular bisector of the base of an isosceles triangle is also the angle bisector of the vertex angle. Thus, as a corollary we know that is EF is the angle bisector of the vertex angle ∠E, then, EF is the perpendicular bisector of the of the base DK.

Please follow the diagram of a complete understanding of the logic and the solution.

As EF is the angle bisector as given in the question, thus we will have:

m\angle DEK=2\times m\angle DE F=2\times 43^{\circ}=86^{\circ}.

Also, from the Theorem we know that KF will be half of DK and thus, KF will be:KF=\frac{1}{2}DK= \frac{1}{2}\times 16=8 centimeters.

Likewise, from the same theorem we have: m\angle EFD=90^{\circ}
