What is the image of (4,−8) after a dilation by a scale factor of 1/4 centered at the origin?

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
