Given the function g(x) = 3x – 1, find x if g(x) = –19.

x = -6

Step-by-step explanation:

If g(x) = -19, then -19 is 3x - 1 since g(x) = 3x - 1.

So, we get the expression -19 = 3x - 1.

Add 1 on both sides: -18 = 3x

Divide both sides by 3: -6 = x

Hope this helped!

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
