Y=2x+10 if I graphed correctly!

Y=mx+b
m=slope
b=y intercept

first find slope

the sloe of the line that passes through the points (x1,y1) and (x2,y2) is
(y2-y1)/(x2-x1)
so the slope of the line that passes through the points (-2,6) and (2,14) is
(14-6)/(2-(-2))=(8)/(2+2)=8/4=2

slope is 2
y=2x+b
find b by subsituting a point

(2,14)
x=2 and y=14
14=2(2)+b
14=4+b
minus 4 both sides
10=b

so the equation is y=2x+10

Help Pls Asap!! Dont really understand the question

PolarNik [594]

Answer: B (the lower one)

Step-by-step explanation:

First let's solve for y.

x + 2y = 4

2y = -x + 4

y = -1/2x + 2

It is B since the y intercept for that graph is 2.

A poker hand consisting of 9 cards is dealt from a standard deck of 52 cards. Find the probability that the hand contains exactl

Andrew [12]

Answer: $\dfrac{^{12}C_{6}\times^{40}C_3}{^{52}C_9}$ or $\dfrac{228}{91885}$ .

Step-by-step explanation:

Given : A poker hand consisting of 9 cards is dealt from a standard deck of 52 cards.

The total number of cards in a deck 52

Number of faces cards in a deck = 12

Number of cards not face cards = 40

The total number of combinations of drawing 9 cards out of 52 cards = $^{52}C_9$

Now , the combination of 9 cards such that exactly 6 of them are face cards = $^{12}C_{6}\times^{40}C_3$

Now , the probability that the hand contains exactly 6 face cards will be :-

$\dfrac{^{12}C_{6}\times^{40}C_3}{^{52}C_9}$

$=\dfrac{\dfrac{12!}{6!6!}\times\dfrac{40!}{3!37!}}{\dfrac{52!}{9!\times43!}}\ \ [\because\ ^nC_r=\dfrac{n!}{r!(n-r)!}]\\\\=\dfrac{228}{91885}$

Hence, the probability that the hand contains exactly 6 face cards. is $\dfrac{228}{91885}$ .
