The graph was horizontally stretched by a factor of 2.

Answer:

x = (59/16)

y = (-65/32)

Step-by-step explanation:

2x + 12y = −17

3x + 2y = 7

--------------------------

(2x + 12y = −17) × 3

6x + 36y = -51

(3x + 2y = 7) × -2

-6x - 4y = -14

----------------------------------

6x + 36y = -51

-6x - 4y = -14

-----------------------

32y = -65

÷32 ÷32

--------------------------

y = (-65/32)

3x + 2y = 7

3x + 2(-65/32) = 7

3x - (65/16) = 7

+(65/16) +(65/16)

-------------------------------

3x = (177/16)

÷3 ÷3

---------------------------

x = (59/16)

Step-by-step explanation:

The domain of the  f(x)=3x-2 form a graph is -∞ < x<∞. See the attached graph. The interval notation is given as (-∞, ∞)

It is to be noted that the domain of a function is the set of input or argument values for which the function is real and defined. Note from the graph that the function has no undefined points nor domain constraints. Hence, the domina is expressed as the notation:

-∞ < x < ∞.

If one were to solve for x,

Then

y = 3x -2

=

3x -2 = y [Flipping the eqation]
3x -2 + 2 = y + 2 {Added two to both sides]

Hence,

3x = y +2

Divide both sides by 3 to get:

3x/3 = (y+2)/3
x = [1/3y] + [2/3]

Step-by-step explanation:

[tex]\frac{-6-0}{-9-h} = 6\\6(-9-h)=-6\\-9-h=-1\\-h=8\\h=-8[/tex]

Answer:

Step-by-step explanation:

Given:

x1 = h

y1 = 0

x2 = - 9

y = - 6

k = 6

_______

h - ?

y = k*x + b

y = 6*x + b

1)

y2 = 6*x2 + b

-6 = 6*(-9) + b

-6 =- 54 + b

b = 54 - 6

b = 48

2)

y = 6*x + 48

y1 = 6*x1 + 48

0 = 6*h + 48

6*h = - 48

Answer: 18.7598

Step-by-step explanation:

4 x 1.50= 6

6+ 3.95=9.95

3x 0.99=  2.97

2.97 + 9.95= 12.92

12.92+ 5= 17.92

6.5% of 12.92= 0.8398

6.5% of 12.92 + 17.92= 18.7598.

The pieces of candies that William gave away is 15.

The linear expression that can be used to determine the number of candies left is:

Pieces of candies left = initial pieces of candies - number of candies given out

Pieces of candies left when William gave out candies : 40 - x

Pieces of candies left when Hannah gave out candies : 70 - 3x

If they have the same pieces of candies left, the two above expressions would be equal.

40 - x = 70 - 3x

3x - x = 70 - 40

2x = 30

x = 15

A statement is 2 less than the quotient of a number y and 3. The algebraic expression is (y/3)-2.

Given that,

A statement is 2 less than the quotient of a number y and 3.

According to question,

An algebraic expression can be written by use of 2  less than the quotient of a number y and 3.

To evaluate an algebraic expression is to determine its value when a certain number is used in lieu of the variable. In order to evaluate an expression, we first replace the variable with the supplied number, then we streamline the expression using the order of operations.

Here, expression is (y÷3)-2=(y/3)-2.

If we substitute the values 0,1,2,3,4...

We get the values between -7 and 4.

Therefore, the algebraic expression for the statement  2 less than the quotient of a number y and 3 is written as (y/3)-2.

a) Number of points the team has  is 18

b) Number of games lost by the team is  9

a) How many point does the team have?

Number of wins the team has  = W= 5

Number of draws the team has  = D= 3

Number of points of the team = P

The equation is given by,

P = 3W +D

P= 3*5 + 3

P = 15+3

P = 18

Number of points the team has 18 points

b) How many games has this team lost?

Number of points of the team =P = 50

Number of draws the team has = D= 14

Number of wins the team has  = W

Number of matches played by the team =T= 35

The equation is given by,

P = 3W +D

50 = 3W+ 14

3W = 50- 14

3W = 36

W = 12

Rewriting as equation,

Lost matches = Total matches - (Win matches+ Draw matches)

                      = T - (W+ D)

                      = 35 - (12+ 14)

Answer: 1 out of 5

Step-by-step explanation: 15 divided by 3 is 5. Which also means out of the 50 cherry tomatoes, 10 of them have bad spots.

The solution to the equations are x = 3 and no solution in the set, respectively

Question 1

The equation is given as:

5x - 6 = 9

The replacement set is given as

{0,1, 2, 3, 4}

So, we replace the variables using the elements in the replacement set

When x = 0, we have

5(0) - 6 = 9

- 6 = 9 -- false

When x = 1, we have

5(1) - 6 = 9

- 1 = 9 -- false

When x = 2, we have

5(2) - 6 = 9

4 = 9 -- false

When x = 3, we have

5(3) - 6 = 9

9 = 9 -- true

Hence, the value of the equation is x = 3

Question 1

The equation is given as:

8x + 4 = 5x - 6

The replacement set is given as

{2, 3, 4, 5}

So, we replace the variables using the elements in the replacement set

When x = 2, we have

8(2) + 4 = 5(2) - 6

20 = 4 -- false

When x = 3, we have

8(3) + 4 = 5(3) - 6

28 = 9 -- false

When x = 4, we have

8(3) + 4 = 5(4) - 6

28 = 14 -- false

When x = 5, we have

8(5) + 4 = 5(5) - 6

44 = 19 -- false

Hence, the value of the equation is not in the solution set

The difference of h and 4 is h-4

to the 10th power, is putting 10 as the exponent.

The value of  x³(x³ - 18) if x(x - 3) = -1 is -1.

To simplify simply means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue.

We have been given that

x(x - 3) = -1 ....... eq(1)

Find out the value of

x³(x³ - 18) ........eq(2)

We first simplify the value of x in equation (1)

x(x−3)=−1

Divide by x on both side

x(x−3)/x = −1/x

(x−3)=−1 /x

Rewrite as

x + 1/x = 3

Taking cube on both sides

(x + 1/x)³ = 3³

x³ + (1/x)³ = 27 - 3×3

x³ + (1/x)³ = 27 -  9

x³ + (1/x)³ = 18

Multiply by x³

x^6 + 1 = 18x³

x^6 - 18x³ = -1

x³(x³ - 18) = -1

Hence, the value of equation x³(x³ - 18) is also -1.

It will take you 45 more minutes to finish walking the remaining distance.

If you have already walked 550 ft, subtracting it to the total distance you need to walk, then the remaining distance will be:

10,000 ft - 550 ft = 9450 ft

Rate is the relationship between two quantities of different units. Rate of speed is the amount of distance over total time.

If you walk at the rate of 210 ft/min, then the time it will take you to finish the remaining distance will be:

rate = distance/time

time = distance/rate

time = 9450 ft/(210 ft/min)

time = 45 mins

Answer:

Mackenzie the answer is the 3rd option:)

Step-by-step explanation:

For given data y varies directly with x and the constant of variation is 2.

And the equation is y = 2x

In this question, we have been given some values of x and y.

we need to determine whether y varies directly with x.

If so, find the constant of variation and write the equation.

x = -2, -4, -16

y = -4, -8, -32

Consider the ratio y/x

-4/-2 = 2

-8/-4 = 2

-32 / -16 = 2

As y/x ratio is constant, y varies directly with x.

and the constant of variation is 2.

Also, the equation from given x, y values would be,

y = 2x

Therefore, for given data y varies directly with x and the constant of variation is 2.

And the equation is y = 2x

From the given statements, the statement which is true when comparing numbers using a number line is :

The number left is always the least.

The definition of a number line is a straight line that shows numbers arranged at equal distances.

A number line is often shown horizontally and can be extended indefinitely in any direction.

Moving right causes the numbers to increase (or become greatest), while moving left causes the numbers to decrease ( or becomes least).

Larger numerals on the number line are always to the left of smaller numbers. Positive numbers have a negative opposite, and negative numbers have a positive opposite. Because it is defined as the distance from zero (the origin) on a number line, the absolute value of any real number is always positive.

Hence the right statement is that the number left is always the least.
