What is the value of m, if the equation my2+2y−4=0 has exactly one root?

Step-by-step explanation:

A quadratic equation has one root if the discriminant is 0.

That is we need for this particular question.

Compare the following to find :

The variable is representative of the variable here.

Plug in into :

Subtract 4 on both sides:

Divide both sides by 16:

Reduce:

m = -1/4

Step-by-step explanation:

B²-4AC = 0 when one real root

(2)² - 4(m)(-4) = 0

4 + 16m = 0

m = -4/16

m = -1/4

56

step-by-step explanation:

$650 per month plus utilities

step-by-step explanation:

just based on the info you gave, it would seem more cost effective to rent at $650 per month plus utilities.   if utilities are, in fact, $150 per month, your monthly living costs would be $800 as opposed to the other option of $825.
