The answer would be : A parallelogram with congruent sides does NOT guarantee that a quadrilateral is a rectangle
Line a intersects both lines c and d.
Line a is a transversal to lines c and d.
Angles 10 and 14 are corresponding angles.
Since corresponding angles are congruent, lines a and c are parallel.
Line b has nothing to do with this question.
Answer is choice A.
Answer:
C f-1 (x) = x- 2
Step-by-step explanation:
The inverse is usually shown by putting a little "-1" after the function name, and reversing the units.
Answer:
y = -2x - 7
Step-by-step explanation:
x - 2y = 6
-2y = -x + 6
Divide the whole equation by (-2)

slope = 1/2
Slope of the line perpendicular to this line = -1/m = -1 ÷ (1/2)

(-3, - 1)
y -y1 = m(x -x1)
y - [-1] = -2(x - [-3])
y + 1 = -2(x + 3)
y + 1= x* (-2) + 3*(-2)
y + 1 = -2x - 6
y = -2x - 6 - 1
y = -2x - 7
