Answer:
(9,4)
Step-by-step explanation:
The given system is:
9x + 3y = 93
3x - 4y = 11
Multiply the bottom equation by 3 to get:
9x + 3y = 93
9x - 12y = 33
Subtract bottom equation from top one to get:
3y--12y=93-33
We put y-value into the bottom equation:
(5, 12) e (-10, -3)
x.......y...1
5.....12..1
-10..-3..1
12x -10y -15 + 120 -5y + 3x = 0
12x + 3x - 10y - 5y - 15 + 120 = 0
15x - 15y + 105 = 0 :(5)
3x - 5y + 21 = 0
m = -a/b
m = -3/-5
m(5) = 3/5
y-yo = m(x-xo)
y-14 = 3/5*(x-7)
y-14 = 3x/5 - 7/5
3x/5 - y + 14 - 7/5 = 0
3x/5 - 5y/5 + 70/5 - 7/5 = 0
3x - 5y + 70 - 7 =0
3x - 5y + 63 = 0
m(s) = -3/-5 = 3/5
m(r) = m(s) --> são paralelas
Step-by-step explanation:
b is the equal ratios just divide 22 and 14 with 2 you gonna get you answer easily
