S is the midpoint of RT. <br> If RS = 4x - 3 and RT = 6x - 4,<br> what’s the value of ST?
Georgia [21]

Answer:

R__S__T

RT = RS + ST

6x – 4 = ( 4x – 3) + ST

(6x – 4 ) – ( 4x – 3 ) = ST

(6x – 4 ) +( – 4x + 3 ) = ST

2x – 1 = ST

ST = 2x – 1

RS=ST

4x – 3 = 2x – 1

4x – 2x = – 1 +3

2x = 2

x= 2/2

x =1

ST = 2x – 1 = 2(1) – 1 =2 ‐ 1 = 1

ST = 1

I hope I helped you^_^

Prove that the line that passes through the points (5,1) and (6,3) is parallel to the line y=2x+3
exis [7]

Answer:

Find slope of other line

Step-by-step explanation:

1) so parallel lines have the same slope

If we find the slope of these two points we can prove those two lines are parallel!

3-1/6-5=2/1

The slope of this line=2

Slope of that line=2

Hence these two Lines are parallel hope this helps!
