2x-4=x+6 solve each multi step equation.
Liula [17]

Answer:

The Answer is: 10.

Step-by-step explanation:

2x - 4 = x + 6

Subtract x from both sides:

2x - x - 4 = x - x + 6

x - 4 = 6

Add 4 to both sides:

x -4 + 4 = 6 + 4

x = 10

Consider a regular deck of cards with 52 cards in total. Four of a kind is a poker hand that contains all four cards of one rank
svet-max [94.6K]

Answer:

No.

Step-by-step explanation:

This is because if one event happens before the other, the odds of the other event happening will change due to less cards being left to pick from.

Consider the scenario where 4 of a kind all contained 10's from the deck.

The possibility of a full-house with a 10 in the pile would be zero if there were no 10's left after the four of a kind turn had been made. Thus, since the four of a kind affects the probability of the full house, and vice versa, they are both dependent on each other and hence not exclusive events.

17. Write the equation of a line that is perpendicular to the given line and that passes through the given point.
nataly862011 [7]

\text{Let}\ k:y=m_1x+b_1\ \text{and}\ l:y=m_2x+b_2.\\\\l\ \perp\ k\iff m_1m_2=-1\to m_2=-\dfrac{1}{m_1}\\\\\text{We have the line in point-slope form:}\\\\y-y_1=m(x-x_1)\\\\m-slope\\\\y-2=\dfrac{7}{3}(x+5)\to m_1=\dfrac{7}{3}\\\\\text{therefore}\ m_2=-\dfrac{1}{\frac{7}{3}}=-\dfrac{3}{7}.\\\\\text{We have the slope}\ m=-\dfrac{3}{7}\ \text{and the point}\ (-4,\ 9).\ \text{Substitute:}\\\\y-9=-\dfrac{3}{7}(x-4))\\\\\boxed{y-9=-\dfrac{3}{7}(x+4)}

VMariaS [17]

Answer:

  (-3 + 5 i) (1) = (-3 + 5 i)

Step-by-step explanation:

The multiplicative identity property says you can multiply anything by 1 without changing its value. That is demonstrated by the equation above.
