Answer:

x-6y=-9

Correct answer: Option b

Step-by-step explanation:

<u>Equation Of A Line </u>

The standard equation of a line is given by

y=mx+b

Where m is the slope of the line and can be computed as

\displaystyle m=\frac{d-b}{c-a}

Where (a,b), (c,d) are two known points of the line. Let's use the points (-3, 1), (3, 2)

\displaystyle m=\frac{2-1}{3+3}

\displaystyle m=\frac{1}{6}

The value of b can be obtained by using any point and the value of m. Let's use (3,2)

\displaystyle 2=\frac{1}{6}(3)+b

b=2-\frac{1}{2}=\frac{3}{2}

The equation of the line is

y=\frac{1}{6}x+\frac{3}{2}

Multiplying by 6

6y=x+9

Rearranging

x-6y=-9

Correct answer: Option b

Solve for x and explain the steps:<br> 3x-6=4(2-3x)-8x
mote1985 [20]

Answer: x = 14/23

Step-by-step explanation:

3x-6=4(2-3x)-8x

3x-6=8-12x-8x --> Expand 4(2-3x)

3x-6=8-20x --> Collect like terms

3x-6+6=8-20x+6 --> Add 6 to both sides, to remove it from the right side

3x=-20x+14

3x+20x=-20x+14+20x --> Add 20x to both sides, to remove it from the left side

23x=14

\frac{23x}{23}=\frac{14}{23} --> Divide both sides by 23

x = 14/23

A certain drink is made by adding 4 parts water to 2.5 part drink mix. What percent of the mixture is water? Omit % sign in your
Maru [420]

The mixture contains 61.5% of water.

<u>Step-by-step explanation:</u>

Total parts = 4+ 2.5 = 6.5

Parts of water =4

parts of drink = 2.5

Percent of water in the mixture = 4 × 100/ 6.5

                                                     = 400/6.5

                                                      = 61.53%

It is rounded to the nearest tenth as 61.5%.

There are 4 aces and 4 kings in a standard deck of playing cards. you pick one random card at random. What is the probability of
hichkok12 [17]

Answer:2/3

Step-by-step explanation:There are 52 cards in a standard deck: 13 ordinal cards (Ace - 10, Jack, Queen, King) and 4 of them - one to each suit (hearts, diamonds, clubs, spades) and so we have

4

×

13

=

52

.

There are 8 cards that fit the question (4 each of aces and kings).

And so in a random draw, the odds of drawing one of those 8 cards out of the total number of 52 is:8/52

which we can simplify:

8/52=2/13
