Answer:

Yes.

Step-by-step explanation:

y = x(x - 1) is a function.

If we draw a graph of the expression we get a parabola which is shaped like a U.

The graph passes the vertical line test for s function (that is - any vertical line drawn through the curve passes through the curve at only one point).

Answer:

224.7 days

Step-by-step explanation:

Venus is the second planet out of the nine planets and it precedes the planet earth. Venus has an orbital distance of 0.72 AU from the sun while Earth has an orbital distance of 149.60 million km from the sun. Due to these distances, the Venus completes one orbit around the sun in 224.7 days while the Earth complete one orbit around the sun in 365.256 days but in a leap year, it completes one orbit around the sun in 366 days.

Amelie has a spinner divided into ninths equal sections that are labeled 1 through 9. she wants to compare the theoretical proba

VMariaS [17]

The theoretical probability = $\dfrac{5}{9}$ , The experimental probability = $\dfrac{5}{12}$

<h3>What is experimental probability?</h3>

The experimental probability of an event occurring is the number of times that it occurred when the experiment was conducted as a fraction of the total number of times the experiment was conducted.

The sample will be ={1,2,3,4,5,6,7,8,9}=9

favourable outcomes={1,3,5,7,9,}=5

The theoretical probability of spinning and odd number = $\dfrac{5}{9}$

As she spends the spinner 12 times

The experimental probability = $\dfrac{5}{12}$

Hence the theoretical probability = $\dfrac{5}{9}$ , The experimental probability = $\dfrac{5}{12}$

What is the value of l-6l - l-8l

trasher [3.6K]

Answer:

-2

Step-by-step explanation:

absolute value is the distance from zero. it will never be negative. so -6 is 6 away from zero, -8 is 8 away from zero. you can just take off the negative sign and use the number by itself.

|-6| - |-8|

6 - 8
