If eg is the median, that means
5x-17=3x+12x=18x=9
M= y2 - y1/ x2 - x1
m= 9-9/-2-2
m= 0/-4
m= 0
The slope is 0
Answer: 
Step by step:
This is the simplest form of this radical.
Answer:
A
Step-by-step explanation:
the standard form of a quadratic equation is
ax² + bx + c = 0 : a ≠ 0
obtain (5 + x)(5 - x) = 7 in this form by expanding the factors
25 - x ² = 7 ( subtract 7 from both sides )
18 - x² = 0 ( multiply through by - 1 )
x² - 18 = 0 ← in standard form
with a = 1, b= 0 and c = - 18 → A
