Find the value of c and YZ if Y is between x and z

XY= 5.5, YZ= 2C, XZ=8.9

Step-by-step explanation:

If Y is between x and z, then XY+YZ = XZ. Given  XY= 5.5, YZ= 2C, XZ=8.9

substituting the given values into the firmula to get c we will have;

5.5+2C = 8.9

Subtract 5.5 from both sides

5.5+2C-5.5 = 8.9-5.5

2C = 3.4

Divide both sdies by 2;

2C/2 = 3.4/2

C = 1.7

Since YZ = 2C, substitute C = 1.7 into the function

YZ = 2(1.7)

YZ = 3.4

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
