A must be parallel to b.
Proof:
∠3 = <span>∠13 (given)
</span>∠15 = <span>∠13 (vertically opposite angles are equal)
Since </span>∠13 = ∠3 and ∠13 = ∠15, ∠15 = <span>∠3
Then, a must be parallel to b (transverse line d cuts parallel lines producing converse alternate angles that are equal (ie </span>∠15 = <span>∠3))
</span>
Answer:
-21
Step-by-step explanation:
All the points should be plotted when doing a scatter plot. This way you will know if there is an outlier, etc.
So the answer is 6
X + 0.5(x + 1) + 4(x + 2) = -30 (where x is the lowest integer)
x + 0.5x + 0.5 + 4x + 8 = -30
5.5x = -38.5
x = -7
The required integers are -7, -6 and -5 (answer).
Answer:
Step-by-step explanation:
6x + 7zy = 15
7zy = 15-6x
y = (15-6x)/7z
