Answer:

{(-14,9),(4,-7),(-8,6)}.

Step-by-step explanation:

To find the inverse you just swap x and y.

So if (a,b) is a point on the relation then (b,a) is on it's inverse.

So the inverse of {(9, –14), (–7, 4), (6, –8)} is:

{(-14,9),(4,-7),(-8,6)}.

Write a quadratic equation with a integer coefficients with roots x= 1/2 and x=-4
Misha Larkins [42]

The quadratic equation with roots a and b is given by:

x^2-(a+b)x+ab=0

Here a=1/2 and b=-4.

So the equation is given by:

\begin{gathered} x^2-(\frac{1}{2}-4)x+(\frac{1}{2})(-4)=0 \\ x^2+\frac{7}{2}x-2=0 \\ 2x^2+7x-4=0 \end{gathered}

The quadratic equation is as shown above.

Which one is bigger and how do you know? 1/8 or 1/9 (Give at least two strategies) i​
scoray [572]

Answer:

1/8 is the bigger fraction

Step-by-step explanation:

When comparing fractions with different denominators, and the numerator is one, like 1/8. The one with the smaller number for the denominator is greater.

You could also compare them by finding common denominators, so for 1/8 and 1/9, a common denominator would be /63. So you would take \frac{1}{8} and multiply that by \frac{9}{9}. You would then get \frac{9}{63}. When you take \frac{1}{9} times \frac{8}{8} you get \frac{8}{63}. So when comparing you can see that 1/8 is greater than 1/9.
