Answer:
1,3,5,345 are factors of 345
Below are I assume the choices, it can be found elsewhere:
A. 15x+10y≥250
B. x+y≤250
C. x+y≥20
D. 15x+10y≥20
E. x+y≤20
<span>F. 15x+10y≤250
</span>
The inequalities that represent constraints for this situation is 15x+10y<=250 and <span>x+y>20. Thank you for posting your question here. I hope the answer helps. </span>
Answer:
Option D is the correct answer
Step-by-step explanation:
The x intercepts of the parabola are the solutions of the equation. These points can be determined either by graphical method or by solving the quadratic equation with any of the methods of solving a quadratic equation.
In order to use the graphical method, values of x are picked and substituted into the equation to get corresponding values of y. The y values are plotted against the x axis and the parabola (downward) is drawn. The points where it cuts the horizontal axis become the solutions of the equation
y = x^2 - 9x + 18
Solving the equation by using the factorization method,
x^2 - 9x + 18 = 0
x^2 - 6x - 3x + 18 = 0
x(x-6)-3(x-6)
(x-6)(x-3) = 0
x -6 = 0 or x -3 = 0
x = 6 or x = 3
The x-intercepts are (3, 0) and (6, 0)
Hey there!
The mean of the numbers is the <u>average</u>. To find the mean we will simply add all the numbers together, and divide them by the amount of numbers there are. Easy, peesy, lemon squeezy. Lets get started.
7 + 10 + 22 + 10 + 12 + 10 + 12 = 83
Now that we have added those altogether, we can divide them by the amount of numbers there are. The amount of numbers there are comes to a total of 7. Therefore...
83 divided by 7 = 11.857
Answer Choice B. 11.9 is your correct answer.
