Answer:
Not simplified: 12:30
Simplified: 1:5
Step-by-step explanation:
We have 12 League A cards and 30 total.
So, 12:30.
But we can divide by 6 and reduce it to its simplest form:
1:5
Please: Use "^" to denote exponentiation: <span>2x^2 + 8x - 12 = 0
Reduce this by div. every term by 2: </span><span>x^2 + 4x - 6 = 0
Here a=1, b=4 and c = -6. Square half of b, obtaining (4/2)^2 = 4, and add, and then subtract, this 4 to x^2 + 4x - 6:
</span> x^2 + 4x +4 - 4 - 6 = 0. Rewrite the square as (x+2)^2, obtaining new equation
(x+2)^2 = 10. Take the sqrt of both sides: x+2 = plus or minus sqrt(10).
Finally, solve for x: x = -2 plus or minus sqrt(10).
Answer:
the answer is 3/7
Step-by-step explanation:
Answer:
3x-13+2x+4=116( the sum of two interior angle is epual to the sum of exterior angle )
5x =116-9
5x=107
x=21.4 degree
then
angle a= 3*21.4-13
a=51.2degree
angle b=2*21.4+2
b =44.8degree

I'm not sure how to display a graph on here, so I'm afraid I can't help you with that part.
However, the answer is C. (-2,3).
To create the graph, either put it into a graphing calculator or manually graph the equations by plugging in different numbers to the equation.
