Answer:
A.
Step-by-step explanation:
Take a look at what happens when squaring either of these...
Notice a couple of patterns.
1. The last term has a positive coefficient. That rules out answer choices C and D.
2. The coefficient of the middle term is either 
. So what are <em>a</em> and <em>b</em>? <em>a</em> is the square root of the x^2 term and <em>b</em> is the square root of the y^2 term.
The middle coefficient needs to be either +30 or -30. The answer is choice A.
Y-y1=m(x-x1)
m= slope =-3
y-y1=-3(x-x1),
y1=-7, x1=5
y--7=-3(x-5)
y+7=-3(x-5) this is C
Answer:
d) 3x+-2y
Step-by-step explanation:
combine like terms of x and y
11x-8x=3x
10x-12x=-2y
