Answer:
School A
Step-by-step explanation:
School A has a ratio of 18/225 = 2/25 staff to students
School B has a ratio of 23/322 = 2/28 = 1/14 staff to students
Assuming that a better ratio means more staff per students School A has a better ratio
Answer:
A
Step-by-step explanation:
So we have the equation:
To solve for x, subtract 4 from both sides:
The left side cancels. Subtract on the right:
So, the value of x is 3.
And our answer is A.
And we're done!
4x = 157.2
4x/4 = 157.2/4
x = 39.3
The function is y = -x^2 - 6x - 13.
The domain is the set of x-values for which the funcion is defined.
In this case, y is defined for all the real numbers.
Answer: all real numbers.
