A) 3x+4=21
3x=21-4
3x=17
x=17÷3
x= 5.7
Translations, rotations, and reflections are all rigid transformations.
It is easier to do if we get rid of the decimals, so lets multiply both numbers by 10:
5.8/1.2 = 58/12
and reduce the fraction:
= 29/6
then operate:
= 4.83
Answer:
-4/3
Step-by-step explanation:
mtan × mline = -1
mtan× 3/4 = -1
mtan =-4/3
