Answer:
A.
Step-by-step explanation:
x^0=1 so you can cancel it out. when a number has a negavite exponent, you have to invert it. That means y^-6 goes at the denominator and becomes y^6 and z^-6 goes up to the numerator and becomes z^6.
Since you're only asked the ordered pair of D'', it's much easier just to plot and reflect point D twice than to do that for all four points!
Remember that reflecting points is like putting a mirror at the line of reflection or flipping that point over at that line. The reflected point should be the same distance from the line of reflection as the original point.
1) Reflect D over the x-axis to get D'.
D is at (4,1). Draw a line that is perpendicular to the line of reflection and goes through D. D is as far from the line of reflection as D' should be on its other side (both are on that perpendicular line). Since D is 1 unit above the x-axis, that means D' is 1 unit below at (4, -1). See picture 1.
2) Reflect D' over <span>y=x+1 to get D''.
D' is at (4, -1). Draw </span>y=x+1 and the line perpendicular to it going through D''. D'' is the same distance from the line of reflection on the other side. See picture 2. D'' is at (-2, 5).
Answer: D'' is at (-2, 5)

Have a nice day
isosceles triangle has its 2 side equals and thus 2 angles opposite to equal side are equal.
consider in a triangle ABC
AB = AC then Angle B = Angle C
so here given angle B = 36
so angle C = 36
now in a triangle sum of all 3 angles is 180
so
angle A + angle B +angle C = 180
angle A + 36 +36 = 180
angle A = 180 - 72 = 108
2)
in a right angle triangle one angle is 90. another one is given as 28
so we kNow sum of all 3 angles is 180
so
third angle + 90 + 28 = 180
third angle = 180 - 118 = 62
