Use the figure shown. Let point D be at (-4,1) . Use the sides of triangle BDA to find the slope of the line.
gavmur [86]

The slope of the line shown in the figure having equation x + 2y = 0 is 1/2.

The point A is at ( -2 , 1 ), point B is at ( -4 , 2 ) and Point C is at ( -2 , 2 ).

Let point D be at ( -4 , 1 ).

Now the new triangle is ΔBDA and the corner points are A is at ( -2 , 1 ), point B is at ( -4 , 2 ) and  point D is at ( -4 , 1 ).

The equation of line passing through two points  is given by:

(y-y_{1} ) = (\frac{y_{2}-y_{1}  }{x_{2} - x_{1} })(x - x_{1} )

The equation of line passing through two points A( -2 , 1 ) and B( -4 , 2 ) IS

y - 1 = ((2-1)/(-4-(-2)))  (x-(-2))

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

2y -2 = -x -2

x + 2y = 0

The equation of straight line is x + 2y = 0

The equation in slope intercept form can be written as,

y = x/2 + 0

Slope = m = 1/2

Intercept = c = 0

So, we can conclude that 1/2 is the slope of the line .

25 is what percent of 20?
denis-greek [22]

Answer:

20 is 80% of 25

Step-by-step explanation:

We assume, that the number 25 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 25, so we can write it down as 100%=25.

4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.

5. Now we have two simple equations:

1) 100%=25

2) x%=20

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=25/20

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20 is what percent of 25

100%/x%=25/20

(100/x)*x=(25/20)*x       - we multiply both sides of the equation by x

100=1.25*x       - we divide both sides of the equation by (1.25) to get x

100/1.25=x

80=x

x=80

HI CAN I GET SOMEONE TO HELP ME WITH MATH IM FAILING TY! :)
oksano4ka [1.4K]

Answer:

20 square meters

Step-by-step explanation:

area = length x width

area of grass = 4 x 4 = 16

area of grass and cement = 6 x 6 = 36

<em>Now you subtract to find the area of the cement.</em>

36 - 16 = 20

Rewrite the expression as a single logarithm and simplify the result.<br> ln lcosxl +lnltanxl
NNADVOKAT [17]
Recall your logarithms rules

\bf ln|cos(x)|+ln|tan(x)|\\\\&#10;-----------------------------\\\\&#10;log_{{  a}}(xy)\implies log_{{  a}}(x)+log_{{  a}}(y)\qquad thus\\\\&#10;-----------------------------\\\\&#10;ln|cos(x)tan(x)|\implies ln\left| cos(x)\cdot \cfrac{sin(x)}{cos(x)} \right|\implies &#10;ln|sin(x)|
