The given compound inequality is
First we solve the first inequality,
Now we solve the second inequality
So we have
So the required solution is
![( - \infty,-5] \ or \ (0, \infty)](https://tex.z-dn.net/?f=%20%28%20-%20%5Cinfty%2C-5%5D%20%5C%20or%20%5C%20%280%2C%20%5Cinfty%29%20)
Correct option is A .
Answer: B. 2 = 3x + 10x2
Step-by-step explanation:
This is the concept of quadratic equations; We required to find the type of equation that can be solved using the model that has been used to solve the equation such that the answer is:
[-3+-sqrt(3^2+4(10)(2))]/(2(10))
The formual that was applied here was a quadratic formula given by:
x=[-b+\-sqrt(b^2-4ac)]/2a
whereby from the our substituted values above,
a=10,b=3 and c=-2
such that the quadratic equation will be:
10x^2+3x-2
0.9874 the greatest non zero place is 9 but the nearest digit is 8 when you round it off to 0.9 the answer becomes 1.0
0.9874~1.0
To solve this, I would just find what two adult tickets and one child ticket wold be worth.
To find that, just do:
5.20 + 9.90 * 2, which makes 25.
So now you just find how many 25s are in 900, or 36.
So 36 children's tickets were sold that day.
Hope I helped :)
The correct answer is D. You can solve this by multiplying the values.
