Solve the following system of equations:
y = -1.5x + 5.7
y = 0.5x + 0.3

step-by-step explanation:

i need to answer questions so i dont know but i think its the first one because it goes up but a consent rate

e.

step-by-step explanation:

because there are always 10 numbers in a phone number.

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

f(x) = y

f(-3) = -5
