Answer:
1 and -2
Step-by-step explanation:
-2x^2=2x-4 so 2x^2 + 2x -4 = 0
2(x^2+x-2)=0
x^2+x-2 = (x-1)(x+2)
x=1 x=-2

I think this is one of the reducing fractions problem:
If we look at option A.{1/4} {1/5} {1/6} {1/7} {1/8}.
Here, the reduced form of all the fractions is not equal to 1/4
If we look at option B. <span>1/4,2/4,3/4,4/4,5/4.
</span>Here, the reduced form of all the fractions is not equal to 1/4<span>
if we look at option C. </span><span>1/4,2/8,3/12,4/16,5/20.
</span>Here, the reduced form of all the fractions is not equal to 1/4<span>
If we look at option D.</span>1/4,2/8,4/16,6/24,8/32.
Here, the reduced form of all the fractions is equal to 1/4
i.e.
1/4 = 1/4
2/8 = 1/4
4/14 = 1/4
6/24 = 1/4
5/20 = 1/4
So, the correct answer is D.
The factors that are needed to be controlled are :
1. the date of manufacturing of the drug should be the same
2. the amount of drug should be the same
3. the time they will take the drug should be the same
4. the food they are taking should be the same
5. the activities they are doing should be the same
Answer:
Step-by-step explanation:
You didn't list the options from which we are to choose as your system of inequalities, but that doesn't matter...we'll come up with them on our own and then you can match them to your options. The first inequality is going to be about the number of hours worked. The second inequality is going to be about the money earned. Hours worked and money earned have to be in 2 different inequalities because they are not the same. If x is one job and y is the other, and the combination of these jobs cannot be more than 12 hours total, then the inequality for this is:
x + y ≤ 12
That represents the hours worked. As far as the money goes, she makes $8 per hour, x, at the first job, and $9 per hour, y, at the second job. She wants the combination of these wages to be at least $100. The inequality that represents the money earned is:
8x + 9y ≥ 100
That is the system that represents your situation.
