We have an equation: 13/?= 26/100
Cross multiply:
26*?= 13*100
⇒ ?= 13*100/26= 50
13 is 26% of 50~

Answer: A) Reflection along the line y = -1
===========================================================
Explanation:
Point A is at (1,5). Point A' is at (1,-7).
Apply the midpoint formula to find the center of these two points.
You should get (1,-1) as that midpoint.
Follow these steps for B(-1,3) and B'(-1,-5) to get the midpoint (-1,-1)
Those midpoints we found are located on the mirror line. We only need two such points to plot it. Drawing a line through (1,-1) and (-1,-1) graphs the equation y = -1. This is the horizontal line through -1 on the y axis.
Answer:
Infinite solutions
Step-by-step explanation:
2x + y = 3
6x = 9 - 3y
2x + y = 3
6x + 3y = 9
3(2x + y = 3)
3(2x) + 3(y) = 3(3)
6x + 3y = 9
