Ok so, basically reflect the shape horizontally across the y - intercept. In the exact same position but reflected across. I’m not sure because I can’t really see the points. Does it give you options? Or do you have to type it?
It’s 19. The absolute value of -7 is 7 and the absolute value of 4 is 4. 7 plus 3 times 4 is 19.
So Sahra is 3 times as old as her daugter. That means that the sum of their age is the daughters age times 4.
We can prove that by saying the daughters age is x. Sahra's age must be 3x. Their sum must be x+3x = 4x.
So to get the daughters age we divide the sum by 4, which is 8.
