12y - 4 = 168
What is y? Use inverse operation

y=14.33

Step-by-step explanation:

the answer is 14.33

Step-by-step explanation:

first you do 12y-4=168

                        +4=+4

                         0=172

so now the eqation is 12y=172

then you divide 172/12=14.33

r(0,90)(x,y) . t(-5,0)

last option

step-by-step explanation:

∆def to ∆d"e"f"

- rotate 90 counterclockwise degrees

- then translated 5 to the left (x --> x - 5)

answer is the last option
