Actually Welcome to the Concept of the Angles,.

Since,the AE is a angle bisector, hence, BAE = EAC simply.

hence we equate them..

===> x+ 30 = 3x - 10

==> 3x - x = 30 + 10

==> 2x = 40

==> x = 20°

hence the major angle EAC = 3(20)-10 = 60-10 = 50°

hence, angle EAC = 50°

Answer:

Option A

Step-by-step explanation:

$A=\begin{bmatrix}-3 & -9 & -3\\ -4 & -3 & 9\\ 7 & 9 & -10\end{bmatrix}$

$-7A=\begin{bmatrix}21 & 63 & 21\\ 28 & 21 & -63\\ -49 & -63 & 70\end{bmatrix}$

$B=\begin{bmatrix}9 & 1 & 6\\ 3 & -10 & 5\\ -1 & 9 & -9\end{bmatrix}$

$-4B=\begin{bmatrix}-36 & -4 & -24\\ -12 & 40 & -20\\ 4 & -36 & 36\end{bmatrix}$

$-7A-4B=\begin{bmatrix}-15 & 59 & -3\\ 16 & 61 & -83\\ -45 & -99 & 106\end{bmatrix}$

Option A is the answer.

Rule 1: Multiply by 2 then add 1 starting from 1.

Lyrx [107]

The sequence 1 will be 3(n – 1) + 1. And the sequence 2 will be 9(n – 1) / 2 + 40.

<h3>What are sequence and series?</h3>

A sequence is a list of elements that have been ordered sequentially, such that members come either before or after.

Let n = natural number.

The sequence 1 will be multiplied by 2 then add 1 starting from 1. Then we have

⇒ 2(n – 1) + 1(n – 1) + 1

⇒ 3(n – 1) + 1

The sequence 1 will be divided by 2 then add 4 starting from 40. Then we have

⇒ (n – 1 / 2) + 4(n – 1) + 40

⇒ 9(n – 1) / 2 + 40

A coordinate grid with 2 lines. The first line is labeled y equals 0. 5 x plus 3. 5 and passes through (negative 3, 1), (negativ

BigorU [14]

Equation of the line is a way to represent the a line in a linear equation form with a set of point given in the graph.The approximate solution of the system given in the question is at point (-2.7,2.1). Thus the option A is correct.

<h3>Given-</h3>

The equation of the first lines which passes from the points (-3,1), (-2.7,2.1), and (0,3.5) is,

$y=0.5x+3.5$

The equation of the second line which passes from the points (-4,3),(-2.7,2.1), and ( 1/3,0) is,

$y=-\dfrac{2}{3}x +\dfrac{1}{3}$

<h3>Equation of the line</h3>

Equation of the line is a way to represent the a line in a linear equation form with a set of point given in the graph.

The two lines in the graph intersect each other at point (-2.7,2.1).

This intersection of two lines indicates that at the point of intersection the coordinates of that point are the solution for the two variables.

Hence, the approximate solution of the system given in the question is at point (-2.7,2.1). Thus the option A is correct.

What is the value 10 years from now of $200 deposited in an account earning 12% interest?

Rzqust [24]

Answer:$440

Step-by-step explanation:

Principal(p)=$200

Rate(r)=12%

Time(t)=10years

Simple interest=(pxrxt) ➗ 100

Simple interest =(200x12x10) ➗ 100

Simple interest=24000 ➗ 100

Simple interest=240

Total amount=p + simple interest

Total amount =200+240

Total amount =440
