Answer:
A x=33
Step-by-step explanation:
log (3x+1) =2
Raise each side to the power of 10 to get rid of the base 10 log
10 ^log (3x+1) =10^2
3x+1 = 100
Subtract 1 from each side
3x+1-1 = 100-1
3x= 99
Divide by 3
3x/3 = 99/3
x =33
its c
if it is rotated in clockwise direction then C'(-2,-3),D'(2,-5),E'(0,-7)
if rotated in anticlockwise direction C'(2,3),D'(-2,5),E'(0,7)
x=0.3
4x-4/5=2/5
4x=4/5+2/5=6/5
x=6/20=3/10=0.3
