Answer:

64

Step-by-step explanation:

The probability of picking an even numbered domino is {number of even numbered dominoes}/{total number of dominoes}. This means that 3/4 = 48/{total number of dominoes}. You divide both sides by 48 and get : 1/64 = 1/{total number of dominoes}. You find the reciprocal of both sides, and get: 64 = {total number of dominoes}

Write the equation in y=mx+b form please????

Solnce55 [7]

ANSWER

$y = - 2x - 5$

EXPLANATION

We can use any two points to determine the slope.

The line passes through;

(-3,1) and (-5,5).

The slope is given by

$m = \frac{y_2-y_1}{x_2-x_1}$

This implies that;

$m = \frac{5 - 1}{ - 5 - - 3}$

$m = \frac{4}{ - 2} = - 2$

We can now find the equation using the formula;

$y-y_1=m(x-x_1)$

$y - 1 = - 2(x + 3)$

Expand:

$y = - 2x -6 + 1$

$y = - 2x - 5$

Need help with number 2 please and thx

It is the second bubble because there can only be one x per y. For example, (1,3) and (1,4) isn't a function because the x which is 1 has too many y

6. What is the greatest common factor of the following expression? *<br> 15y3 – 40y

Nady [450]

Answer:

I'm not sure what 15y3 is, but I'll take a guess.

If the only numbers are 15, 3, and -40, then the greatest common factor is 1.

If the only numbers are 15 and 3, then it's three.

If the only numbers are 15 and -40, it would be 5.
