Answer:
11 and 12
Step-by-step explanation:
AD is opposite BC so they're equal, and DC is opposite AB so they're the same.
Answer
A. Many solution
Step by step explanation
Points on line 1 : (-3, 6) and (3, 4)
Points on line 2: (-6, 7) and (9, 2)
Now let's find the slope of the line 1
Slope formula = 
Slope of line 1 = (4 - 6) / (3 - (-3)
= -2/(3 + 3)
= -2/6
Slope of line 1 = -1/3
The equation of the line y - y 1 = m(x - x1)
y - 6 = -1/3 (x - (-3))
y -6 = -1/3 (x + 3)
y -6 = -1/3x - 1
y = -1/3x + 5
Slope of line 2 = (2 - 7) / (9 -(-6))
= -5/(9 + 6)
= -5/15
Slope of line 2 = -1/3
The equation of line
y - y1 = m(x - x1)
y - 7 = -1/3(x - (-6))
y - 7 = -1/3(x + 6)
y -7 = -1/3 x - 2
y = -1/3 x + 5
The line 1 and line 2 have the same slopes and the same y-intercept. Both are the same equation. Therefore, there will be many solution.

Thank you.
Answer:
4) A
5) E
Step-by-step explanation:
#4


Cross multiply the equation and you get:

Since
is the same thing as
, you can change the equation into 
Cancel out the y on the top and bottom and you get 1/10
#5
, simplify and you get
so x=15
is equal to
after you plug in x, and that is equal to 9
Usually it’s around the percentage of about forty five percent
