Answer:

(8,-1)

Step-by-step explanation:

The point of intersection can be found out by solving the system of equations.

  1. x + 3y = 5
  2. 3x - 2y = 26

<u>Multiply</u><u> </u><u>(</u><u>1</u><u>)</u><u> </u><u>by </u><u>3 </u><u>:</u><u>-</u><u> </u>

→ 3 ( x + 3y ) = 5 × 3

→ 3x + 9y = 15

<u>Subtracting</u><u> </u><u>3(</u><u>1</u><u>)</u><u> </u><u>and </u><u>2</u><u> </u><u>:</u><u>-</u><u> </u>

→ 3x + 9y - 3x +2y = 15 - 26

→ 11y = -11

→ y = (-1)

<u>Put </u><u>it </u><u>in </u><u>1</u><u> </u><u>:</u><u>-</u>

→ x -3 = 5

→ x = 3 + 5

→ x = 8

<h3>Hence the point of intersection is (8,-1)</h3>

Answer:

the ans is :

Step-by-step explanation:

First, it would be helpful to draw a quick sketch of the lines. It helps to visualize the problem.

To find the intersection point, we need to find the point where x and y are the same value in both equations.

The line equations:

6x+2y=26 ................... 1

2x+3y=18 ................... 2

Can be rearranged to the common line equation form: y = mx + c

y = 13 - 3x ................... 3

y = 6 - 2/3 x ................. 4

At the intersection point, y will be equal for both equations. So, we can set 3 equal to 4 and solve for x.

13- 3x = 6 - 2/3 x

13 = 6 + 3x - 2/3x ....... add 3x to both sides

13 = 6 + 2 1/3x ........ simplify

7 = 2 1/3 x ........ subtract 13 from both sides

7 = 7/3 x ......... multiply both sides by 3/7

3 = x

To calculate the y-coordinate substitute x = 3 into 3.

y = 13 - 3x

y = 13 - 3(3)

y = 4

To check your answer, substitute the values for x and y into the other equation, 4.

The point of intersection is (3,4).

If you drew a sketch of the problem, you should be able to see that this point of intersection makes sense.

Suppose that m∠MKN = 55°. What is m∠MCN?<br> !please no absurd answers!
Elena L [17]

Answer:

angle M and N are right angles

we can draw a line joining M and N  

so we’d have a triangle MNC AND KMN

both MNC AND KMN BECOME ISOSCELES TRIANGLES

so since we have 55 degrees for angle MKN. We have to find the other 2

180-55=125

now divide by 2 to get 62.5 for each of the remaining sides of triangle KMN

now to find the sides of triangle MNC

90-62.5= 27.5

27.5*2= 55

180-55=125=angle C

(sorry, it’s complex)

Can someone explain the steps for how do solve this?! I can’t get it right
Ulleksa [173]

Answer:

x = 50

m∠D = 150°

m∠F = 30°

Step-by-step explanation:

  • supplementary angles are two angles whose sum is 180°

∠D + ∠F = 180°

3x + x - 20 = 180

3x + x = 180 + 20

4x = 200

x = 200/4

x = 50

D = 3*50 = 150

∠D = 150°

F = 50 - 20 = 30

∠F = 30°
