Answer:</h3>
∠C = 40°
∠D = 75°
<h3>
Step-by-step explanation:</h3>
AB ║ CD, so AD and BC are transversals. The angle pairs (A, D) and (B, C) are "alternate interior angles", hence congruent.
∠C = ∠B = 40°
∠D = ∠A = 75°
Hey there! :)
Answer:
29/28.
Step-by-step explanation:
Starting with:

Begin by finding a common denominator. A number that contains all of the denominators as a factor would be 28. Change each fraction to contain a denominator of 28:

Add the fractions:

Therefore, the fractions sum up to 29/28.
Answer:
A: (-9,-3)(-2,-4)(-5,-8)
B: (-5,2)(-1,-3)(3,2)
C: (4,-7)(-1,-3)(4,1)
D: (-1,-11)(-2,-4)(-6,-7)
Step-by-step explanation:
So of the transformations, translations are pretty much the easiest. x-1 just means move all coordinates left 1 and y-3 means move all coordinates down 3. So for the first one the x coordinate gets 1 subtracted from it and the y value gets 3 subtracted from it.
(-8,0) => (-8-1, 0-3) = (-9,-3)
I do recommend double checking though, for practice and in case I flubbed a calculation.
Answer:
15x + 14y = -18
Step-by-step explanation:
slope = (6 - -9)/(-8 - 6) = 15/-14
y = mx + b
6 = -15/14(-8) + b
6 = 60/7 + b
b = -18/7
y = -15/14x - 18/7
15/14x + y = -18/7, multiply everything by 14
15x + 14y = -18
