I would convert into decimals it's easier to do then multiply 9/12*1 3/4 and if your teacher wants it into fractions convert it back

increments over the exponent, are not directly proportional to increments on the resulting values, namely the half-way from 10² and 10⁴ is not 10³, because 10⁴ is 100 times 10², and 10³ is simply 10 times 10².

Write an example of a trinomial that cannot be factored.

OverLord2011 [107]

Answer:

$x^{2} + x + 1$

Step-by-step explanation:

a trinomial that cannot be factored has no real roots.

here is one:

$x^{2} + x + 1$

After graphing this trinomial has no intersections points with the x-axis wich means it has no roots

The ordered pair (3, –1) is a solution of which system?

Alexxandr [17]

Answer:

In your equation, put 3 where x is, and -1 where y is. If you get a true statement, like -8 = -8, or 69 = 69, then (3, -1) is a solution. If you get a false statement, like 9 = 21 or 10 = 420, then (3, -1) is not a solution.
