Answer:
Co ordinate of A' = (1, -4)
Co ordinate of B' = (3, 2)
Co ordinate of C' = (4, -2)
Explanation:
The figure of the triangle is shown below.
If we are finding image of the triangle about X-axis all the x -co-ordinates will remain same, but y co-ordinate will change it's sign.
So, co ordinate of A' = (1, -4)
Co ordinate of B' = (3, 2)
Co ordinate of C' = (4, -2)
1/2x + 5 = 35
You use 1/2 because she sold half of her books . Then +5 because she gained 5 back and 35 because your end total should be 35.
Hope this helps ! :)
