Answer:
Step-by-step explanation:
The lines will be parallel if corresponding angles are congruent (z=x) or if adjacent interior angles are supplementary (x+y=180°).
__
The other relations can be true without forcing the lines to be parallel.
Answer:
R23 470
because 3 is below 5 so =0
If you would like to know the values of b and c, you can calculate this using the following steps:
an = b * c^(n-1)
a1 = - 5
a1 = b * c^(1-1) = b * c^0 = b * 1 = b
_______________
b = - 5
a2 = 10
a2 = <span>b * c^(2-1) = (-5) * c ^1 = (-5) * c
_______________
10 = (-5) * c
c = - 2
</span><span>an = b * c^(n-1) ... an = (-5) * (-2)^(n-1)
a3 = </span>(-5) * (-2)^(n-1) = (-5) * (-2)^(3-1) = (-5) * (-2)^2 = (-5) * 4 = -20
a4 = (-5) * (-2)^(n-1) = (-5) * (-2)^(4-1) = (-5) * (-2)^3 = <span>(-5) * (-8) = 40
</span>
The correct result would be: b = -5 and c = -2.
