Answer:

They are the same

Step-by-step explanation:

We are to check if (-5 + -3 ) =( -5 - +3)​

First you must know that the product of a positive and a negative n=sign will result in a negative sign i.e. + * - = -

Applying this in question;

(-5 + -3 )

= -5 - 3

= -8

similarly

( -5 - +3)​

= -5 - 3

= -8

Since both values are the same hence, (-5 + -3 ) =( -5 - +3)​

A number n is increased by 8. If the cube root of that results equals -0.5, what is the value of n?
jek_recluse [69]

The cube root of (n increased by 8), or  ∛(n+8), is -0.5, or -1/2.

∛(n+8) = -1/2.  To solve this for n, cube both sides, obtaining n+8 = -1/8.

Eliminate the fraction by mult. all three terms by 8:             8n + 64 = -1

Solving for n:  8n = -65, so that n = -65/8.

Oscar played games vs number of points he scored is, C) positive, linear association.

Step-by-step explanation:

  • no association is when points Oscar graph will remain between 8to10.
  • number of games he scored his points remain the same which is mean.
  • non linear is only when there is no straight line passing.
  • Linear is either exponential or polynomial.
  • Positive as the game increase he scoring abilities increases.
  • Negative as the game increases his scoring decreases.
  • Negative x axis will have more number of points.
  • Negative y axis will high to low of the graph.
  • Linear lines are best way to predict a data doesn't work will all data.
