Answer:

y = -3x; the const. of prop. is -3.

Step-by-step explanation:

Recall:  a proportional relationship satisfies y = kx, where k is the constant of proportionality.

In this particular example we see that (-3)(-2) = 6, (-3)(1) = -3, and (-3)(2) = -6.

This confirms adherence to the equation of a proportional relationship.  The constant of proportionality here is -3.

The function governing the table is y = -3x.

The y-intercept would represent the highest point. The graph will show a parabola and this point will only be reached once.

The x-intercept would be the starting point and the ending point. You can find total distance traveled with this.

NO SCAM PLEASEEEE

The answer is 11/36

2/12 chance of rolling fours

because there are 2 sides containing a four on both dice combined and 12 sides in total.

Doubles mean you have to roll the same number simultaneously so let’s say we want to calculate the probability for double ones: then it’s 1/6 on the first dice for a one, and 1/6 on the second dice to land on a one as well.

I personally like to imagine a box like this:
_ _ _ _ _ _

If you have one dice then it’s just a random segment on one of the lines. If you want the specific result from two dice then you want two specific segments which is also the 1 specific tile out of 36 (6 width times 6 height). So you multiply.

1/6 * 1/6 = 1/36 chance to roll double of ones

And 1/36 chance to roll double twos, threes, fours, fives, and sixes. But we don’t count the double fours because any four will do. So:

1/36 * 5 = 5/36

So for the probability of either doubles or containing a four is the probability of doubles of either number plus the probability of either dice being a four:

5/36 + 2/12 =

5/36 + 6/36 =

11/36

The first thing you should do in this case is to compose both functions:
 f (x) = x + 7
 g (x) = 1 / (x-13)
 Making the composition
 f (g (x)) = (1 / (x-13)) + 7
 f (g (x)) = (7 (x-13) +1) / (x-13)
 Answer:
 The domain of the function is:
 x other than 13
 (option 4)

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ Angles on a straight line equal 180 degrees:

5k - 3 + 9 + k = 180

Simplify:

6k + 6 = 180

Subtract 6 from both sides:

6k = 174

Divide both sides by 6:

k = 29
