<h3>Answer:  62</h3>

Explanation:

K is the midpoint of segment JL

That means the smaller pieces JK and KL are the same length.

JK = KL

9x-5 = 7x+3

9x-7x = 3+5

2x = 8

x = 8/2

x = 4

This x value leads us to:

  • JK = 9x-5 = 9*4-5 = 36-5 = 31
  • KL = 7x+3 = 7*4+3 = 28+3 = 31

Both smaller pieces are 31 units each, which helps confirm we have the correct x value.

Therefore, JL = JK+KL = 31+31 = 62

The x - intercept of 5x - 3y = 15 is (3, 0)

The y -intercept of 5x - 3y = 15 is (0, -5)

<h3><u>Solution:</u></h3>

Given equation is 5x - 3y = 15

<em><u>To find: x - intercept and y -intercept</u></em>

The x intercept is the point where the line crosses the x axis. At this point y = 0

The y intercept is the point where the line crosses the y axis. At this point x = 0.

<em><u>Finding x - intercept:</u></em>

To find the x intercept using the equation of the line, plug in 0 for the y variable and solve for x

So put y = 0 in given equation

5x - 3(0) = 15

5x = 15

x = 3

So the x - intercept is (3, 0)

<em><u>Finding y - intercept:</u></em>

To find the y intercept using the equation of the line, plug in 0 for the x variable and solve for y

So put x = 0 in given equation

5(0) - 3y = 15

-3y = 15

y = -5

So the y - intercept is (0, -5)
