If you look at the model RM is the same length as PM. PM=10 so RM=10.
16x^2-40x+25 Yes I know my phone is messed up but at least you got the answer
27 has to be C
I can't see the whole question for 28 and 29
Answer:
the answer is A
Step-by-step explanation:
Answer: Graph shifts 4 units to the left
Explanation:
I'm assuming you meant to say y = |x+4|
If so, then the graph shifts 4 units to the left. Replacing x with x+4 moves the xy axis 4 units to the right if we held the V shape in place (since each x is now 4 units larger). This gives the illusion the V shape is moving 4 units to the left.
Or you could look at the vertex point to see how it moves. On y = |x|, the vertex is at (0,0). It then moves to (-4,0) when we go to y = |x+4|
