Which equation is in point-slope form and depicts the equation of this line?

1 answer:

crimeas [40]3 years ago

4 0

Answer:

i believe the answer is A

Step-by-step explanation:

(y + 4) = -(1)/(3)(x + 1)

distribute -1/3 to (x+1)

(y+4)= -1/3x + -1/3

subtract 4 from each side

y= -1/3x - 13/3

What is the simplest form of the radical expression?

BaLLatris [955]

I believe the equation is
$4 \sqrt[4]{2x} + 6 \sqrt[4]{2x}$
In this case, you would simplify it by adding them together.
$4 \sqrt[4]{2x} + 6 \sqrt[4]{2x}$ = $10 \sqrt[4]{2x}$
And can even be changed to an exponential equation:
$10(2x)^{ \frac{1}{4} }$

The following formula relates three quantities: Force (F), mass (m), and acceleration (a).

Pie

(a) F=ma

a=F/m

(b) a=25/10

a=2.5

2.5*10=25

(c) m= 25/5

m=5

5*5=25

Find the missing segment in the attached image

xz_007 [3.2K]

Answer:

The length of the missing segment is 24

Step-by-step explanation:

Given

The figure above

Required

Determine the missing segment

Let the missing segment be represented with x

Given that, there exist parallel lines between the two triangles;

The relationship between the sides of the triangles is as follows;

$\frac{15}{x} = \frac{15+5}{8+x}$

$\frac{15}{x} = \frac{20}{8+x}$

Cross Multiply

$15 * (8 + x) = 20 * x$

Open bracket

$15*8 + 15 * x = 20 * x$

$120 + 15x = 20x$

Subtract 15x from both sides

$120 + 15x -15x= 20x-15x$

$120 = 20x-15x$

$120 = 5x$

Divide both sides by 5

$\frac{120}{5} = \frac{5x}{5}$

$\frac{120}{5} = x$

$24 = x$

$x = 24$

Hence, the length of the missing segment is 24

Oint C is on line segment BD‾\overline{BD} BD . Given BD=5x,BD=5x, BD=5x, BC=4x,BC=4x, BC=4x, and CD=4,CD=4, CD=4, determine the

Gennadij [26K]

Answer:

Therefore the required value of $\overline{BD}$ is 20 units.

Step-by-step explanation:

Line Segment: Line segment is a portion of a line whose has two end points.

Given that point C is on the line segment $\overline{BD}$ .

$\overline{BD}$ = 5x , $\overline{BC}$ = 4x and $\overline{CD}$ = 4

C is the point of the line segment of $\overline{BD}$ .

So we can write

$\overline {BD}= \overline{BC}+\overline{CD}$

Putting the values of $\overline{BD}$ , $\overline{BC}$ and $\overline{CD}$

5x=4x+ 4

⇒5x-4x= 4

⇒x=4

So we get the value of x.

To get the value of $\overline{BD}$ , we need to put the value of x in the value of $\overline{BD}$ .

Therefore,

$\overline{BD}$ = 5×4

=20

Therefore the required value of $\overline{BD}$ is 20 units.
