Answer:

The answer is

Step-by-step explanation:

To find an equation of a line given a slope and a point we use the formula

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

where

m is the gradient

( x1 , y1) is the point

From the question

Gradient = 2

The point is ( 1 , 4)

The equation is

$y - 4 = 2(x - 1) \\ y - 4 = 2x - 2 \\ y = 2x - 2 + 4 \: \:$

We have the final answer as

$y = 2x + 2$

Hope this helps you

Hey there! :D

Subtract 20% by 10%, because it is asking how much less than the original price was by what percent.

Question 4 Multiple Choice Worth 1 points)<br> (01.02 MC)<br> Solve for :<br> 2 x -<br> (x - 2) = 4x

oee [108]

Answer:

$\small \sf \frac{2}{3} = x \\$

Step-by-step explanation:

Solve for x;

2x - ( x - 2 ) = 4x

distribute minus sign through parantheses

2x - x + 2 = 4x

combine like terms

x + 2 = 4x

subtract x from both side

x - x + 2 = 4x - x
2 = 3 x

Divide each side by 3

$\small \sf \frac{2}{3} = \frac{3x}{3} \\$

$\small \sf \frac{2}{3} = x\: \\$

Of the 2,598,960 different five-card hands possible from a deck of 52 playing cards, how many would contain all black cards.

kumpel [21]

Answer: 65,780

Step-by-step explanation:

When we select r things from n things , we use combinations and the number of ways to select r things = $^nC_r=\dfrac{n!}{(n-r)!r!}$

Given : The total number of playing cards in a deck = 52

The number of different five-card hands possible from a deck = 2,598,960

In a deck , there are 26 black cards and 26 red cards.

The number of ways to select 5 cards from 26 cards = $^{26}C_{5}=\dfrac{26!}{(26-5)!5!}$

$=\dfrac{26\times25\times24\times23\times22\times21!}{21!(120)}=65780$

Hence, the number of different five-card hands possible from a deck of 52 playing cards such that all are black cards = 65,780
