B. (4, 4) is a solution to the equation.
Answer:
y=3x+1
Step-by-step explanation:
y=mx+c
Gradient is 3
Rise/run=3/1=3
Y intercept=1
y=3x+1
Answer:
D or the Last one
Step-by-step explanation:
because the equation equals that and it is a perfect square method because the middle term is not canceled out. Hope this helps!
Answer:
i dont help girls
Step-by-step explanation:
Part A is accomplished by first factoring out the b^2 to get

. Factor that completely using the quadratic formula to get

. Part B is done entirely with the quadratic formula (only cuz that's the easiest way to factor a second degree polynomial!) to get (x-9)(x-9) or (x-9) multiplicity 2. Part C is done by taking roots. Keep in mind that since this is a second degree polynomial you will have 2 solutions.

, therefore,

and

which is +11 and -11. And you're done! Factoring is very important...make sure you learn it and learn it well!!!
