Add 7 and 3 8ths meters plus 6 and 1 third meters. Does the sum belong to the set of rational number integers or whole numbers?
PSYCHO15rus [73]
Rational number integers because the sum using (LCD) is 13 and 17/24. Therefore, the answer can not be a whole number because it is in a fractional form. You can also put this number in a rational for which would be 312/24. This proves that it is a rational number.

Write the equation with both x= 8 and x= -8 as solution
nlexa [21]

Answer:

y = x^2 - 64

Step-by-step explanation:

Hello!

We can use the factored form of a Quadratic to find an equation with 8 and -8 as our solution.

<h3>Factored Form: y = a(x - h)(x - k)</h3>

The value in each parenthesis should be 0. So 8 and -8 can be flipped and used for h and k.

  • y = a(x - h)(x - k)
  • y = a(x - 8)(x+ 8)

This will give roots 8 and -8 for x.

  • y = 1(x - 8)(x + 8)\\
  • y = x^2 - 64

A possible equation is y = x^2 - 64.
