Well, first off, let's find what is the slope of BC
now, a line perpendicular to that one, will have a negative reciprocal slope, thus
now, we know the slope "m" of AB is -2 then, thus
y = 3x - 1
x - y = -9
Subs y in second equation.
x - (3x - 1) = -9
x - 3x + 1 = -9
-2x = -9 - 1
-2x = -10
x = -10/-2
x = 5
Subs x
y = 3x - 1
y = 3.5 - 1
y = 15 - 1
y = 14
The solution is false!
3.1 would become a fraction that will be calculated back into a decimal by the 4th power making it 92.3521=3,600.. so the equality is false because the left hand and the right hand side are different.
3 sig figs in the final answer since the denominator has 3 sig figs. So the answer would be 4.05
Answer:
false
