I'm sorry but your question doesn't make sense. Maybe you worded it wrong.
Answer:
A. y + 1 = -2(x – 5)
Step-by-step explanation:
For a line with slope m through point (h, k), the equation is ...
y -k = m(x -h)
Fill in your values of m=-2, h=5, k=-1 and you have ...
y -(-1) = -2(x -5)
y +1 = -2(x -5) . . . . . . simplify. Matches selection A.
You have to extract common factor 3a^2
=> 3a^2 (5 x^2 + 4x + 3)
If you need help to know where each term inside the parenthesis come from, this is hoy you do it:
15a^2x^2
------------- = 5x^2
3a^2
12a^2x
----------- = 4x
3a^2
9a^2
-------- = 3
3a^2
Answer: 3a^2 (5x^2 + 4x + 3)
The relationship between the miles and the total cost is, for every 1 mile at the cost of $.40 you will have to pay an initial fee of $1.75.
The charge for a one-mile drive is $2.15 (C=.40*1+1.75)
The charge for a 2.7 mile ride will be $2.83 (C=.40*2.7+1.75)
