Answer:
(-2,3)
Step-by-step explanation:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). Notice that B is 5 horizontal units to the right of the y-axis, and B' is 5 horizontal units to the left of the y-axis. the y-axis is the point (-x,y).

Answer:
x= -1/21
Step-by-step explanation:
21x + 11 - 5 = 5
21x + 6 = 5
(-6 each side)
21x = -1
(divide 21 each side)
x= -1/21
Answer: T (The first option).
Step-by-step explanation:
1. By definition, coplanar points are three or more points that are in the same plane.
2. Based on this information, as you can see in the figure attached, the points A, C, D, E, S and U are coplanars because they are in the same plane, which is: ACDE.
3. Therefore, you can conclude that the point T is not coplanar with points A, C and D because this is not in the plane ACDE.
A unit rate is a ratio that has a denominator of 1. A unit rate is also called a unit ratio. (They mean the same thing.)
\frac{5}{4} and 3:8 and 40\mbox{ to }10 are ratios, but they are not unit ratios.
\frac{1.25}{1} and 0.375:1 and 4\mbox{ to }1 are unit ratios.
Any ratio can be converted into a unit ratio by dividing the numerator and the denominator by the denominator.
