The range of the function f (x) = -3x are (0, -3, 6).

What is Domain?

The set of all inputs of the function is called Domain of set.

Given that;

The domain of f(x) = -3x is (0, 1, 2).

Now, Domain of the function are the values of x.

So, We find the Range of the function as;

Substitute all the values of domain (x) in the given function as;

The function is;

f (x) = -3x

For x = 0

Range = f (x) = - 3 × 0 = 0

For x = 1;

Range = f (x) = - 3 × 1 = -3

For x = 2

Range = f (x) = 3 × 2 = 6

Thus, Range of the function are (0, -3, 6)

Therefore, The range of the function f (x) = -3x are (0, -3, 6).

Answer:

Step-by-step explanation:

Zero exponent numbers = 1

When you try to multiply an exponent by zero, it equals one.

Negative exponents is just a 1/x

Negative just flips over the equation.

For example, 9^-1

1/9^1

1/9

Answer:

Step-by-step explanation:

Zero Exponent Property: The zero exponent rule states that when a nonzero number is raised to the power of zero, it equals 1.

Example:  x^0 = 1

Negative Exponent Properties: the negative exponent rule tells us that a number with a negative exponent should be put to the denominator, and vice verse. It also describes how many times we have to multiply the reciprocal of the base.

An example of negative exponents is [tex]3^{-2}[/tex].

The cups of sugar needed is 2.5 cups.

The cups of flour needed is 3.75 cups

The cups of butter needed is 1.25 cups.

Given the information in the question, the ratio of sugar to flour to butter is 1 : 1.5 : 0.5

Cups of sugar needed = (ratio representing sugar / sum of ratios) x total number of cups

Sum of ratios = 1 + 1.5 + 0.5 = 3

Cups of sugar needed = (1 / 3) x 7.5 = 2.5 cups

Cups of flour needed = (ratio representing flour / sum of ratios) x total number of cups

Cups of flour needed = (1.5 / 3) x 7.5 = 3.75 cups

Cups of butter needed = (ratio representing butter / sum of ratios) x total number of cups

Cups of butter needed = (0.5 / 3) x 7.5 = 1.25 cups

The length of a side of the square=4x-1

The perimeter of the square=4a

Where a is the side of the square

Substitute the values in the equation

The perimeter of the square=4(4x-1)=16x-4

The length of the rectangle=2x+1

The width of the rectangle=x+2

The perimeter of the rectangle=2(l+w)

The division expression to find the number of cups of flour Max needs to use if he has only 1 egg is M ÷ N cups of flour.

1 egg = M/N cups of flour.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Let M cups of flour be needed for N eggs.

This can be written as:

N eggs = M cups of flour

Divide both sides by N.

1 egg = M/N cups of flour

Thus,

The division expression to find the number of cups of flour Max needs to use if he has only 1 egg is M ÷ N cups of flour.

Answer:

Both the lights will flash 1440 times a day. Proof: Red light flashes after every 30 seconds and green light flashes after every 20 seconds.

Step-by-step explanation:

The equation y = 2/3x + 1  has a solution of (6, 5) and not (9, 8)

From the question, the equation is given as

y = 2/3x + 1

Also, we have the ordered pairs to be

(6, 5) and (9, 8)

For (6, 5), we have

x = 6 and y = 5

So, the equation becomes

5 = 2/3 x 6 + 1

Evaluate

5 = 5 --- true

For (9, 8), we have

x = 9 and y = 8

So, the equation becomes

8 = 2/3 x 9 + 1

Evaluate

8 = 7 --- false

Hence, (6, 5) is part of the solution and (9, 8) is not

f(-9) = 23

they seem to be right :p

Step-by-step explanation:

The length is 16.6ft and the width is 8.9ft

Area of the rectangular area = Length × width

A = LW … 1

If he wants to have a rectangular area  of turf with length one foot less than 3 times the width, then

L = 3W - 1 … 2

Substitute 2 into 1

A = (2W-1)W

A = 2W^2 - W

Since area = 150sq.ft

150 = 2W^2 - W

2W^2 - W - 150 = 0

Factorize

2W^2 - W - 150 = 0

W = 1±√1+4(300)/2(2)

W =  1±√1201/2(2)

W = 1±34.655/4

W = 35.655/4

W = 8.91375

W = 8.9 (to nearest tenth)

Get the length

L = A/W

L = 150/8.9

L = 16.85

L = 16.6ft

Hence the length is 16.6ft and the width is 8.9ft

The empty table should be completed with the coordinates of the transformed graph after a dilation with a scale factor of 3 as follows;

x              m(x)

4              -2

2              -1

0              0

-2              1

-4              2

The equation of the resulting line in slope-intercept form is y = -0.5x + 3.

Based on the given coordinates of the graph of function f(x), the dilation with a scale factor of 3 from the origin (0, 0) or center of dilation would be calculated as follows:

Point 1 (-2) → Point 1' (-2 × -2) = Point 1' (4).

Point 2 (-1) → Point 2' (-1 × -2) = Point 2' (2).

Point 3 (0) → Point 3' (0 × -2) = Point 3' (0).

Point 4 (1) → Point 4' (1 × -2) = Point 4' (-2).

Point 5 (2) → Point 5' (2 × -2) = Point 5' (-4).

Next, we would translate the graph of function f(x) 3 units up as follows:

Point 1 (-2) → Point 1' (-2 + 3) = Point 1' (1).

Point 2 (-1) → Point 2' (-1 + 3) = Point 2' (2).

Point 3 (0) → Point 3' (0 + 3) = Point 3' (3).

Point 4 (1) → Point 4' (1 + 3) = Point 4' (4).

Point 5 (2) → Point 5' (2 + 3) = Point 5' (5).

Now, we can determine the slope of the transformed graph:

Slope, m = Δy/Δx

Slope, m = (y₂ - y₁)/(x₂ - x₁)

Slope, m = (2 - 1)/(2 - 4)

Slope, m = -1/2 or -0.5

Mathematically, the slope-intercept form of a straight line is given by;

y = mx + c

Where:

At point (2, 2) and y-intercept c = 3, we have:

y = mx + c

y = -0.5x + 3

Therefore, the height of the cuboid is 3 cm.

In a case whereby Kaylie is 6 years old and  Her sister, Amanda is 2x younger. Kaylie is now 36 the, Amanda age will now be expressed as  33 years.

This implies that when  Kaylie is 6 years old  then her  Her sister, Amanda will be 6/2 = 3 years old.

Then we were told again that Kaylie is now 36, then the age of Amanda will now be (36-3)= 33 years

This is because when Kaylie was 6 years old , she was older by her sisiter by just just 3 years, which is still the same when she grown in age again, the 3 years interval is maintained.

Answer:

v = -16

Step-by-step explanation:

Move the variable to the left-hand side and change its sign, so it would then be -28 - v = -12

Then move the constant to the right-hand side and change its sign, so it would become - v = -12 + 28

Then you would calculate the sum: - v = 16

After doing so, change the sides on both sides of the equation, v = -16

So, your answer should be v = -16

1. The difference between a number and seven eighths exceeds negative two thirds is:

Let the number be f.

This will be:

f - 7/8 > -2/3

2. The expression negative one eighth j plus two thirds minus the expression five thirds j plus nine twelfths will be:

= -1/8j + 2/3 - 5/3j + 9/12

= -1/8j - 5/3j + 9/12 - 8/12

The required value of x is 34° in figure 4, x is 57° in figure 5, x is 81° in figure 6, x is 122° in figure 7, x is 65° in figure 8, x is 54° in figure 9, x is 90° in figure 10, x is 60° in figure 11, and x is 62° in figure 12.

In any equilateral triangle, the three angles are of equal measure and they equal 60 degrees.

As per figure 4,

x° + 56° + 90° = 180

x = 180 - 146

x = 34°

As per figure 5,

x = 57°

As per figure 6,

36 + 90/2 + 180-x = 180

36 + 45 - x = 180 - 180

x = 36 + 45

x = 81°

As per figure 7,

By the property of Equilateral Triangles

⇒  x = 180 - 58

⇒  x = 122°

As per figure 8,

By the property of Isosceles Triangles

x + 115 = 180

x = 180 - 115

x = 65°

As per figure 9,

6 + x + 60 + 60 = 180

x = 180 - 60 - 60 - 6

x = 54°

As per figure 10,

By the property of Equilateral Triangles

60/2 + 60 + x = 180

x = 180 - 60 - 30

x = 90°

As per figure 11,

By the property of Equilateral Triangles

2(30) + 60 + x = 180

x = 180 - 60 - 60

x = 60°

As per figure 12,

28 + 90 + x = 180

x = 180 - 118
