Answer:
Step-by-step explanation:
there are function that "invert" each other..
subtraction inverts addition...
3+2 = 5 ... 5-2 = 3
division inverts multiplication
5*2 = 10 ... 10/2 = 5
Using that concept, "factoring" is basically the inverse of multiplication
3x^2 + 9x can be factored to 3x(x+3)
if you multiply that out it reverts back to the original equation
so x^2 + 5x + 6 factors to (x+3)(x+2)
if you multiply that out (foil it)
you get x^2 + 5x + 6
Answer:
the first one is 10*6 and the second one is 10+7
Step-by-step explanation:
Answer is A because the number line is going by 2
Answer:
Step-by-step explanation:
perp. 5/2
y - 1 = 5/2(x - 2)
y - 1 = 5/2x - 5
y = 5/2x - 4
