The two figures are congruent because the side lengths are the same, therefore making the angle measures the same.
X + 2y = 6
2y = -x + 6
y = -1/2 x + 3 so slope = -1/2
parallel lines has same slope = -1/2
perpendicular lines slope is opposite and reciprocal so slope = 2
if slope not equal either -1/2 or 2 then neither.
y = -1/2 x - 5 ....m= - 1/2.... parallel
-2x + y = -4
y = 2x - 4...m = 2 ....perpendicular
-x + 2y = 2
2y = x + 2
y = 1/2 x + 1 ...m = 1/2 ...neither
x + 2y = -2
2y = -x - 2
y = -1/2 x - 1 ...m = -1/2 .....parallel
hope it helps
Answer:
Step-by-step explanation: Subtract b from both sides to isolate mx :
y - b = mx + b - b
y - b = mx
STEP 2 :
Divide both sides by x in other to isolate x
(y - b) / m = mx / m
(y - b) /m = x
Therefore, making x the subject gives the final equation as : x = (y - b) /m
Answer:
b
Step-by-step explanation:
because 2/8 + 1 7/8 is 2 1/8
Answer:
7 x − y = 17
Step-by-step explanation:
Apply the distributive property.
y + 3 = 7 x+ 7 ⋅ − 2
Multiply 7 by − 2 .
y + 3 = 7x − 14
Rewrite the equation with the sides flipped.
7 x − 14 = y + 3
Move all terms containing variables to the left side of the equation.
Subtract y from both sides of the equation.
7x−14−y=3
Move -14.
7x−y−14=3
