Answer:
9

Step-by-step explanation:
Find what both expressions have in common
First you have to find a common denominator which is 8.
1/2 =4/8
7/8 - 4/8 = 3/8
So the answer is 3/8.
Answer:
(-1/2, 23/4)
Step-by-step explanation:
Vertex of graph: -b/2a
b=1
a=1
Therefore, -1/2 is your x-value
Solve for y: y=1/4-1/2+6
y=5 3/4 or 23/4
Therefore your vertex is: (-1/2, 23/4)

Answer:
70
Step-by-step explanation:
two opposite interior angles =an exterior angle
11x-5+14x=120
25x-5=120
25x= 120+5
25x=125
25x/25=125/25
x = 5
angle S= 14x
= 14(5)
=70°
