Write the slope-intercept form of the equation of the line described by (−1, −1), parallel to y = −2x − 4

LuckyWell [14K]

Answer:

y = -2x - 3

Step-by-step explanation:

Slope intercept form of line is

y = mx + c

where

m is the slope and c is the y intercept

________________________________________

Given that line

y = −2x − 4

comparing it with y = mx + c

m = -2 and c = -4

Thus, slope of this line is -2

we also know that when two lines are parallel then their slopes are same

thus, slope of required line will be m = -2

___________________________________________

now let the equation of line passing through (-1,-1) be

y = mx + c

we have found m to be -2

using this in above equation we have

y = -2x + c

since (-1,-1) passes through the above line using x = -1 and y = -1

we have

-1 = -2*-1 + c

-1 = 2 + c

c = -1 - 2 = -3

using c = -3 in y = -2x + c

we have

equation of line as

y = -2x - 3 in slope intercept form.

A tank is 4 feet long, 6 feet wide and 10 feet tall. How much water can that tank hold?

prohojiy [21]

Answer:

Volume = 240 feet³

Step-by-step explanation:

We'll find it's volume

Volume = $Lenth *Width*Height$

Where Length = 4, Width = 6, Height = 10

Volume = 4 * 6 * 10

Volume = 240 feet³

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
