A reflection across the line y=0 (AKA the x-axis)
and then across the line x=0 (AKA the y-axis)
is the same as a rotation of 180º
clockwise about the origin because the lines intersect at the origin and at a 90º angle.
While all of that is true, you could also be more general, because reflecting over any two lines that intersect at the origin will result in a rotation about the origin and have an angle of rotation equal to twice that of the acute angle formed between the intersecting lines.
Answer: the first adds increasingly by 1 every time. (+6,+7,+8...) the next two numbers are 35 and 45.
The second multiplies increasingly by one every time. (x5,x6,x7...) and the next two numbers are 1680 and 13,440
Answer:
Lines 2 and 4 are perpendicular
Step-by-step explanation:
Line 2: 4y=3x-4
y=3/4x - 1
Line 4: 4x+3y=-6
3y=-6-4x
y=-2 - 4/3x
The two lines are perpendicular since -4/3= - (inverse of 3/4)
