y2-y1
x2-x1
Set up (-3,5) and (7,-9)
Which will be...
Y2=-9
y1=5
X2=-3
X1=7
Put the y coordinates on top of the x coordinates and subtract...
That;s your answer
the missing number should be the square root of the last number times 2 for a perfect trinomial
so square root of 49 = 7
7*2 =14
so the missing number should be 14
Answer:
Assuming the 2 at the ends are the exponents,
the answer is -x^2-5x+6 (x^2+5x-6)
from here, it cannot be simplified more
Explanation --
Just add everything by putting the terms in parentheses and adding them.
Keep simplifying by putting the like terms together and adding/subtracting them.
At the end, you come up with -x^2-5x+6, so multiply -1 on the whole thing (by putting parentheses on its sides. This makes x positive. But they are the same thing, but this step is just for simplifying the end product a little more.
Hope this helps!! Have a nice day!
Answer:
I think it's B
Step-by-step explanation:
750 has to be greater so that eliminates the last two. Then it said the number of weeks after starting his collection. He was purchasing 25 cards of week before starting his collection. It may not make sense so don't trust me whatsoever but I hope it helped?
