Answer:
AC Midpoint (2,0)-
CB Midpoint (5,-4)
midlength is 5
Step-by-step explanation:
midpoint formula 
A(2,4) C(2,-4)

(2,0)
C(2,-4) B(8,-4)

midpoint is (5,-4)
Distance between the 2 midpoints is the midsegment
(2,0) and (5,-4)


Answer:
8. x = 16
9. x = 10
14.
m ∠RSU = 130°
m ∠UST = 50°
15.
m ∠RSU = 124°
m ∠UST = 56°
Step-by-step explanation:
8.
Given ∠DEF is bisected by EG. That is , ∠DEG = ∠GEF
That is , (x + 15)° = 31°
x = 31 - 15 = 16
9.
Given ∠DEF is bisected by EG. That is , ∠DEG = ∠GEF
That is ,
(6x - 4)° = 56°
6x = 56 + 4
6x = 60
x = 10
14.
13x + 5x = 180° [straight line angles ]
18x = 180
x = 10
m ∠RSU = 130°
m ∠UST = 50°
15.
4x + 12 + 2x = 180° [ straight line angles]
6x = 180 - 12
6x = 168
x = 28
m ∠RSU = 4(28) + 12 = 112 + 12 = 124°
m ∠UST = 2(28) = 56°
The range refers to the value of y for which x is define.
So let y=f(x),

Try making x the subject to obtain,

x is defined for all real values of y greater than
0.
Hence the correct answer is D.
Answer:
x=8
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
–5(3 – q) + 4 = 5q – 11
-15 +5q + 4 = 5q -11
-11 + 5q = 5q - 11
+5q - 5q = -11 + 11
0=0
