1. Find the measure of line LM if M is the midpoint of line LN and LM = 3x – 2 and MN = 2x + 1.

Veronika [31]

<u>1. </u> If M is the midpoint of line LN , then the length of LM and MN will be equal to each other.

Given that, LM= 3x -2 and MN= 2x+1

So, the equation will be....

$3x-2= 2x+1\\ \\ 3x-2x= 1+2\\ \\ x=3$

So, the measure of LM will be: $3x-2=3(3)-2 = 9-2= 7$

<u>2.</u> Suppose, the co ordinate of point G is (x, y)

Co ordinate of point J is given as (6, -2)

If point F is the midpoint of line GJ , then the co ordinate of F will be: $(\frac{x+6}{2}, \frac{y-2}{2})$

Given that, the co ordinate of F as (1, 3.5)

So,

$\frac{x+6}{2}=1 \\ \\ x+6=2\\ \\ x= 2-6=-4$

and

$\frac{y-2}{2}= 3.5\\ \\ y-2= 7\\ \\ y= 7+2 =9$

So, the co ordinate of point F will be (-4, 9)

The two lines below intersect as shown What is the value of x?

Rufina [12.5K]

Answer:

x = 6

Step-by-step explanation:

because we know the lines intersect we also know the 2 angles are vertical meaning they are equal to each other

Knowing the angles are equal to each other you can make the equation

2x + 29 = 9x - 13

then you solve for x in this equation

2x + 29 = 9x - 13

(subtract 2x from both sides)

29 = 7x - 13

(add 13 to both sides)

42 = 7x

(divide by 7 on both sides)

6 = x

x = 6
