Subtract −7a2+3a−9−7a 2 +3a−9minus, 7, a, squared, plus, 3, a, minus, 9 from 5a2−6a−45a 2−6a−45, a, squared, minus, 6, a, minus, 4.

After subtracting from , the answer is:

Step-by-step explanation:

The given expressions are:

Expression 1:

Expression 2:

According to the question, expression 1 has to be subtracted from expression 2.

Writing it mathematically,

The minus between both expression, when solved, will change the signs of the terms in expression 1

So,

Combining alike terms(i.e. combining squared terms together and similarly linear and constant terms)

After subtracting from , the answer is:

i believe the correct answer is b.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
