Answer:

In order to describe the pattern of the number of dots as a function of the picture number you have to take the average values of each number and find the line of best fit between each dot. This gives you a function, such as, f(x) = mx+b.

Answer:

-4 5/12

Step-by-step explanation:

Explanation: I would do this problem by setting up a chart.

For the equation x = 3, if we set up a chart for x and y,

since x must be equal to 3, the random values we

choose in this problem are not for x, they are for y.

If we had an equation like y = 2x + 3, then we would pick values for x

and plug them into the equation to get y, but here, x is our only value.

So let's choose the values 1, 0, and -1 for y.

For each of these values, x must be equal to 3.

So we have the points (3, 1), (3,0), and (3, -1).

Notice that our graph is a vertical line, as I showed this below.

Answer:y=-4.6667

Step-by-step explanation:

Answer:  y= -4

Step-by-step explanation:

6y + 2 = 9y + 14      Subtract 2 from both sides

      -2             -2

6y = 9y + 12             Subtract 9y from both sides

-9y    -9y

-3y = 12      Divide both sides by -3

y= -4

Answer: The "rise over run" is equivalent to 1/3

Step-by-step explanation:

Since the m variable in the equation is 3, the line is going to be wider, there for it will go up 1 and 3 to the right with each point on the line, therefore the answer is B.

The requried slope of the line is 3, which is a positive number. Therefore, the line has a positive slope, and option D is true.

The equation is the relationship between variables and represented as y = ax + b.

Here,
A.

The y-intercept is -7.
The equation y = 3x - 7 is in slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept. Therefore, the y-intercept of this line is -7, not 7, as given in option A.

B.
The "rise over run" is equivalent to 3. Option B is not correct.

C.
point (1, 4) lies on the line.

To check whether the point (1, 4) lies on the line, we can substitute x = 1 and y = 4 into the equation y = 3x - 7 and see if the equation is true:

y = 3x - 7

4 = 3(1) - 7

4 = -4

Since the equation is not true, the point (1, 4) does not lie on the line, and option C is false.

D.
The line has a positive slope.

As we determined earlier, the slope of the line is 3, which is a positive number. Therefore, the line has a positive slope, and option D is true.

Step-by-step explanation:

Answer:

30,000 milliliters

Step-by-step explanation:

There are 15 2-liter bottles, so you must get the total number of liters by multiplying 15 and 2 to get 30. Then, because there are 1,000 milliliters per liter, you multiply 30 by 1,000 to get 30,000 milliliters total.

Answer:

y=2x-7

Step-by-step explanation:

2 would equal M because m is your slope.

-7 would be your y intercept

following y=mx+b

The required equation of the line is given as y = 2x -7.

Given that,
The slope of 2 and y-intercept of −7

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

Here,
The equation of the line is given as.
y = mx + c
Substitute the value in the equation,
y = 2x - 7

Thus, the required equation of the line is given as y = 2x -7.

Answer:

We know that:

Each mechanic can change the oil of 3 cars per hour.

The number of mechanics can change between 0 and a maximum of 4.

Then we can write the variable:

Y = number of oil changes per hour.

Y = 3*X

Where X is the number of mechanics working.

The independent variable is X (number of mechanics), because is the one that Zach can change, and the dependent is Y (number of oil changes) because this depends on the value of X.

Now, the domain will be: {0, 1, 2, 3, 4}

The possible numbers of mechanics working at the same time.

And for the range we must replace those values in our equation, and see the possible values of Y.

Y(0) = 3*0 = 0

Y(1) = 3*1 = 3

Y(2) = 3*2 = 6

Y(3) = 3*3 = 9

Y(4) = 3*4 = 12

Then the range is: {0, 3, 6, 9, 12}

Answer:

Let s = each square foot of wood installed

Step-by-step explanation:

Total cost of laying wood = base price + price for each square foot installed

Base price = $250

Price for each square foot installed = $3.50

Let

s = number of each square foot installed

Total cost of laying wood = $250 + $3.50s

The correct answer is

Let s = each square foot of wood installed

The total number of passwords possible is given by the permutation equation A = 26 x 25 x 24 x 10 x 9

A permutation is an ordered arrangement.

The number of ordered arrangements of r objects taken from n unlike objects is:

Permutation nPr = ( n )! / ( n - r )!

Given data ,

Let the total number of passwords be represented as A

Now , the equation will be

The number of digits in the password = 5 digits

For the first three digits, he chooses different letters of the alphabet

So , total number of digits that are alphabets out of the 26 alphabets = 3

For the last two digits, he chooses a different number

between 0-9

The total number of digits that are numbers out of the 10 numbers = 2

So , the permutation will be

A = 26P3 x 10P2

Substituting the values in the equation , we get

The total number of passwords A = ( 26 )! / ( 26 - 3 )! x ( 10 )! / ( 10 - 2 )!

On simplifying the equation , we get

The total number of passwords A = ( 26 )! / ( 23 )! x ( 10 )! / ( 8 )!

And ,

The total number of passwords A = 26 x 25 x 24 x 10 x 9

Therefore , the value of A is 14,04,000

Hence , the permutation is 26P3 x 10P2
