Answer:
n = ± 6
Step-by-step explanation:
absolute value equations usually produce 2 solutions
to get the positive solution just solve normally: 2n - 4 = 8
2n = 12
n = 6
to get the negative solution you must take what is in the absolute value bars and multiply by negative one: -(2n) - 4 = 8
-2n - 4 = 8
-2n = 12
n = -6
Answer:
Yes
Step-by-step explanation:
We know that because AB and CD are parallel,
- angles A and D are supplementary
- angles B and C are supplementary
As supplements of congruent angles are congruent, this means angle B is congruent to angle C.
Thus, ABCD is a parallelogram because it is a quadrilateral with 2 pairs of opposite congruent angles.
Answer:
He must pay $129.45 and the total amount due is $3,629.45.
Step-by-step explanation:
I (interest) =P (principal) x R (rate) x T (time)
I=3500x.09x150/365
I=129.45
A (amount due) = P (principal) + I (interest)
A= 3500 + 129.45
A= $3629.45
Answer:
C. y = -3
Step-by-step explanation:
Line L is perpendicular to the y-axis, so line L is just a straight horizontally line going from left to right.
This mean that the x-coordinate they gave us is irrelevant since our flat line is going to pass through all possible x-values. The only thing we need to focus on the the y-value.
So we know that the line passes through (__, -3)
the equation y = -3 gives us a horizontal line that passes through (__, -3).
Therefore answer is C.
Answer A and B are wrong because they gave us vertical lines, we want horizontal lines. D and E are wrong because those are diagonal lines, we want flat horizontal lines.
