The Angles depicted 38° and (6x + 2)° are equal because they form vertical opposite Angle pair.

so,

6x + 2 = 38

6x = 38 - 2

6x = 36

x = 36 ÷ 6

x = 6

This question says “use the given conditions to write an equation for the line in point-slope form and in slope intercept form”.

Ipatiy [6.2K]

Answer:

Step-by-step explanation:

y = -4x + 5.....slope here is -4. A parallel line will have the same slope.

y = mx + b

slope(m) = -4

(-6,-2)....x = -6 and y = -2

now we sub and find b, the y intercept

-2 = -4(-6) + b

-2 = 24 + b

-2 - 24 = b

-26 = b

so ur equation is : y = -4x - 26 <====

The area of a circle is 113.04 in.^2. What is the radius of the circle?

Lelechka [254]

$\bf \textit{area of a circle}\\\\
A=\pi r^2\qquad 
\begin{cases}
r=radius\\
------\\
A=113.04
\end{cases}\implies 113.04=\pi r^2
\\\\\\
\cfrac{113.04}{\pi }=r^2\implies \sqrt{\cfrac{113.04}{\pi }}=r$

Three vertices of a parallelogram are shown in the figure below. Give the coordinates of the fourth vertex.

topjm [15]

Given:

The three vertices of a parallelogram are (-3,8), (4,5), (2,-5).

To find:

The fourth vertex of the parallelogram.

Solution:

Let the vertices of the parallelogram are A(-3,8), B(4,5), C(2,-5) and D(a,b).

We know that, diagonals of a parallelogram bisect each other. It means midpoints of both diagonals are same.

Midpoint formula:

$Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)$

Two diagonals of ABCD are AC and BD.

Midpoint of AC = Midpoint of BD

$\left(\dfrac{-3+2}{2},\dfrac{8-5}{2}\right)=\left(\dfrac{4+a}{2},\dfrac{5+b}{2}\right)$

$\left(\dfrac{-1}{2},\dfrac{3}{2}\right)=\left(\dfrac{4+a}{2},\dfrac{5+b}{2}\right)$

On comparing both sides, we get

$\dfrac{4+a}{2}=\dfrac{-1}{2}$

$4+a=-1$

$a=-1-4$

$a=-5$

And,

$\dfrac{5+b}{2}=\dfrac{3}{2}$

$5+b=3$

$b=3-5$

$b=-2$

Therefore, the coordinates of fourth vertex are (-5,-2).
