Answer:
B. y=x²-x-6
Step-by-step explanation:
Consider the product ...
0 = (x -a)(x -b) = x² -(a+b)x +ab
This equation has solutions x=a and x=b. You will note that ...
- the constant is the product of the solutions (ab)
- the coefficient of x is the opposite of their sum (-(a+b))
For solutions of -2 and 3, the constant will be (-2)(3) = -6. This eliminates choices C and D.
The sum of the solutions is -2+3 = 1, so the coefficient of x is -1, matching choice B.
-4+6
or it could be written out as
n-4+6=x
Consecutive angles of a parallelogram are supplementary, so:
This means 
and that 
.
Since opposite angles of a parallelogram are congruent,
Answer:
There are 18 seniors and 25 juniors.
Step-by-step explanation:
- Find your equation. For this equation, it comes out to be:
x + x + 7= 43 or 2x+7=43
X represents the amount of seniors.
The amount of juniors can be represented as x+7
- Solve the equation. It comes out to be:
1st - Transfer the 7 to the other side to get the x by itself
2x=36
2nd - Divide 36 by 2 to leave x by itself
x=18
- Answer the question. Because you didn't specify what your were asking for, I imagine it's the number of player from each class.
Because x represents the seniors, there are 18 seniors.
There are 7 more juniors, add 7 to 18, so there's 25.
