Rewrite the equation;

3x-y=3
3x-3=y

Linear equation.

I'm unsure of what the second part asks. Can you rewrite the given question?

(a) $^{6}C_1 * ^{6}C_1 = 36$ different possibilities
(b) $P(even die 1): \frac{1}{2}$
$P(even die 2): \frac{1}{2}$

So, there is a 1 in 4 chance that both dice will show an even.

Complete the square to determine the minimum or maximum value of the function defined by the expression.

FrozenT [24]

Answer:

Option D. minimum value at −38

Step-by-step explanation:

we have

$x^{2}-12x-2$

Let

$y=x^{2}-12x-2$

Complete the square

$y+2=x^{2}-12x$

$y+2+36=(x^{2}-12x+36)$

$y+38=(x^{2}-12x+36)$

$y+38=(x-6)^{2}$

$y=(x-6)^{2}-38$ ------> equation of a vertical parabola in vertex form

The vertex is the point $(6,-38)$

The parabola open upward-----> the vertex is a minimum

therefore

minimum value at −38

3(4*5)=(3*4)5 what is thsi

Serggg [28]

This is the associative property. Basically if you move the parenthesis either to left or right you’ll still get the right answer. So 4 times 5 equals 20 and 20 times 3 equals 60. 3 x 4 equals 12 and 12 x 5 equals 60

Solve the equation for x. 1 3 (6x − 9) = −33

KIM [24]

Answer:

<u>x = 1.07</u>

Step-by-step explanation:

13 ( 6x - 9) = -33

78x - 117 = -33 ( opening brackets and multiplying )

78x = 84 ( - 117 taken to the other side makes it positive)

x = 84 / 78
