A Discrete variable is countable in a finite amount of time while a Continous variable is uncountable in a finite amount of time.

Therefore, grouping the variables into Discrete and Continous, we have:

a) The fuel efficiency, in miles per gallon, of an American-made car >>> Continous variable.

b) The number of personal-injury traffic accidents last week on Interstate 65 in Indiana >>>Discrete variable.

c) In an experimental study, the participant's estimate for the height of a 3-meter image >>> Continous variable.

d) The highest grade level (1st, 2nd, or 3rd) completed by a high-school dropout >>> Discrete variable

The value of x in this system of equations is 1.
maria [59]

<em>Answer:</em>

<em>In my opinion the answer is </em><em><u>y = 6</u></em>

<em>Step-by-step explanation:</em>

<em>We have two unknowns from the equation therefore, two equations are needed. These equations are: </em>

<em> </em>

<em>3x + y = 9  </em>

<em>y = –4x +10  </em>

<em> </em>

<em>To solve for y, we first substitute the second equation to the first one. </em>

<em>3x + –4x +10= 9  </em>

<em>x = 1 </em>

<em> </em>

<em>We substitute the value of x to either of the equations and solve for y. </em>

<em> </em>

<em>y = –4(1) +10  </em>

<em>y = 6</em>
