Answer:
x = -2
x= -3
Step-by-step explanation:
x 2+5x+6=0
To solve the equation, factor x^2+5x+6 using formula x^2+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.
a+b=5
ab=6
Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 6.
1,6
2,3
Calculate the sum for each pair.
1+6=7
2+3=5
The solution is the pair that gives sum 5.
a=2
b=3
Rewrite factored expression (x+a)(x+b) using the obtained values.
(x+2)(x+3)
To find equation solutions, solve x+2=0 and x+3=0.
x=−2
x=−3
Lets check the first point (0,6)
3*0+4=4 no good
0+6 =6 good
0^2+6 =6 good
6 * (7/6) ^0 =6 good
Lets check the second point (1,7)
3*1+4= we don't care since it didn't work for (0,6)
1+6 =7
1^2+6 =7
6 * (7/6) ^1 =7
Lets check the third point (2,10)
3x+4= we still don't care
2+6 = 8 no good
2^2+6 =10 good
6 * (7/6) ^2 =6 * 49/36 =49/6 no good
f(x) = x^2 +6
What you must keep in mind is that there are 4 jeans in total, which represents 100%
When she bought two jeans, we have the following information:
If both of them are blue:
50% of their jeans is blue now, that is:
x = (50/100) * 4 = 2
2 jeans are blue.
This means that she did NOT have 2 blue jeans before.
Thus:
If they are not blue:
We have 4 jeans that are not blue.
Then, 0% of her jeans is blue now
answer:
0% percentage of her jeans is blue now
Answer:
20%
