Answer:
- 6 x - 182
Step-by-step explanation:
Answer:
Step-by-step explanation:
12x - 2 + 20x - 10 = 180
32x - 12 = 180
32x = 192
x = 6
12*6 - 2
72 - 2 = 70
the solution is b
For
ax+by=c
slope=-a/b
perpendiculare lines have slopes that multiply to -1
so
2x+3y=9
slope=-2/3
-2/3 times what=-1
what=3/2
point slope form
the equation of a line that passes through the point (x1,y1) and the slope is m is
y-y1=m(x-x1)
slope=3/2
point i (8,5)
equation is
y-5=3/2(x-8)
converted to standard form
2y-10=3x-24
-3x+2y=-14
3x-2y=14
