Use distributive
3f - 15 - 9 = -3
Combine like terms
3f - 24 = -3
Add 24
3f = 21
Divide by 3
f = 7
Interior angles of a triangle add up to 180
48 + 6x - 28 + 2x = 180
8x + 20 = 180
8x = 180 - 20
8x = 160
x = 160/8
x = 20
< A = 48
< B = 6x - 28......6(20) - 28 = 92
< C = 2x.....2(20) = 40
-78, -61, -47, -32. With negative numbers while ignoring the negative sign the larger the number, the smaller it really is in value
Translation of 2 units left, and a reflection across the x axis :)
