What do you need to do to a variable with a coefficient? For example: 4n=20.
add
subtract
divide
multiply

wouldnt it be 5

Step-by-step explanation:

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

i believe that the answer is

b. y-1=-2(x-4)

hope this !
