What is the correct equation

y = 0.4x

In fraction form, this is y = (2/5)x

Explanation:

For each row, divide the y over x values

We end up with the same thing each time.

Since y/x = 0.4, this rearranges to y = 0.4x

Alternatively, you can write the equation as y = (2/5)x because 2/5 = 0.4

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

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
