Examine this system of linear equations. y – 3x = –2, y = 4. Which is a solution of the system of equations?
Svetlanka [38]

Answer:the third option is the correct answer

Step-by-step explanation:

The given system of linear equations is expressed as

y – 3x = –2 - - - - - - - - - - - -1

y = 4 - - - - - - - - - - - - - 2

The first step is to substitute equation 1 into equation 2. It becomes

4 – 3x = –2

Subtracting 4 from the left hand side and the right hand side of the equation, it becomes

4 - 4 - 3x = –2 - 4

- 3x = - 6

Dividing the left hand side and the right hand side of the equation by - 3, it becomes

- 3x/ - 3 = - 6/ - 3

x = 2

(2, 4)

What is value of x?<br><br><br><br> Enter your answer in the box.<br> x =
Ghella [55]

The bisector divides the line BC in the following ratio.

(x + 8) / 10 = (2x - 5) / 14      Cross Multiply

14(x + 8) = 10(2x - 5)            Remove the brackets.

14x + 112 = 20x  - 50           Subtract 14x from both sides . Add                                                                                                                             50 to both sides

112 + 50 = 20x - 14x             Collect like terms

162 = 6x                               Divide by 6  

x = 27

Help pls it’s the the last Q
sesenic [268]

Answer:

HN = 102 units

LJ = 90 units

GJ = 176 units

Step-by-step explanation:

Since, point N inside the triangle is the circumcenter of the given circle,

HN = GN = NJ = Radii of the circle

Therefore, measure of HN = measure of GN = measure of JN = 102 units

By applying Pythagoras theorem in ΔNLJ,

JN² = NL² + LJ²

(102)² = (48)² + (LJ)²

(LJ)² = (102)²- (48)²

LJ = √8100

LJ = 90 units

m(GJ) = 2[m(GK)] [Since NK bisects GJ]

          = 2(88)

          = 176 units
