( 2x − 27 ) ( −x + 15 )
= ( 2x + −27 ) ( −x + 15 )
= ( 2x ) ( −x ) + ( 2x ) ( 15 ) + ( −27 ) ( −x ) + ( −27 ) ( 15 )
= −2x^2 + 30x + 27x − 405
= −2x^2 + 57x − 405
The answer is C. -1+-6=-7, not 7.
Answer:
D
Step-by-step explanation:
Because it is x - 7, we know it has a phase shift of + 7 to the right.
We also know that since +1 is in the equation, there is a vertical shift of + 1.
Hope this helps
Answer: Definitely C (and I'm assuming A since there are 2 answers but I can't see A that well)
Step-by-step explanation: Its not B because B is 7
Its not D because D is 5
Its not E because E is 7
You are looking for -3, so C is the only correct on.
Not sure about A. I can't see it
