PLEASE HELP URGENT I DONT GET THE QUESTION : Describe the single transformation that has the same effect as reflecting across the line x= 1 followed by a reflection across the line x = 5

Let's say we had point A at (0,0). It is exactly 1 unit away from the vertical line x = 1. We move 1 unit to the right to land on this mirror line, and then move another unit to arrive at A ' (2,0)

So A(0,0) moves to A ' (2,0) after mirroring over the line x = 1.

Then note the distance from A ' (2,0) to the second mirror line x = 5 is 3 units. We'll move 3 units to the right to land on this second mirror line, and then another 3 units to the right to arrive at A '' (8,0)

Overall, we start at A(0,0) and ended at A '' (8,0)

This describes a horizontal translation of 8 units to the right.

Step-by-step explanation:

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
