<span>18d – 2m + 9k < 5k + 10.
Choices:
m > –7k – 9d + 5
m < –7k – 9d + 5
m > 2k + 9d – 5
m < 2k + 9d – 5
-2m < 5k + 10 - 18d - 9k
-2m < 5k - 9k + 10 - 18d
-2m < -4k + 10 - 18d
Notice when the coefficient of the variable is a negative number, its inequality sign is reversed when it is divided by the negative number.
m > -4k/-2 + 10/-2 - 18d/-2
m > 2k - 5 + 9d
or
m > 2k + 9d - 5 ====> 3rd option.

Answer:
Step-by-step explanation:
Start with:
Distribute the values on the outside of each of the parentheses.
Combine like terms.
Subtract from both sides of the equation.
Subtract from both sides of the equation.
Now, we need to use our quadratic equation formula:

I think you meant to say
(as opposed to <em>x</em> approaching 2)
Since both the numerator and denominator are continuous at <em>t</em> = 2, the limit of the ratio is equal to a ratio of limits. In other words, the limit operator distributes over the quotient:
Because these expressions are continuous at <em>t</em> = 2, we can compute the limits by evaluating the limands directly at 2:
They could be 45, 46 and 47.
