Answer:

x int (4,0)

y int (0, -6)

Step-by-step explanation:

Answer:

(4, -6)

Step-by-step explanation:

To solve for the x-intercept, plug in 0 for y. To solve for the y-intercept, plug in 0 for x. You do this because the x-intercept is the point at which the line intercepts the x-axis, meaning y would equal 0, and the y-intercept is the point at which the line intercepts the y-axis, meaning x would equal 0.

Answer:

P = 2(l+w)

P = 2(7x+5)

P = 14x+5

A = L x W

A = (3x - 5) * 4x

A = 12x^2 - 20x

The area and the perimeter of the rectangle are 12x² - 20x and 14x - 10 respectively.

The figure in the diagram is a rectangle.

The area and perimeter of a rectangle are expressed as:

Area A = length × width

Perimeter P = 2( length + width )

From the diagram:

Length = 3x - 5

Width = 4x

Area A =?

Perimeter P =?

Plug the expressions into the above formulas to solve for the area and the perimeter:

Area A = length × width

Area A = ( 3x - 5 ) × 4x

Area A = 12x² - 20x

The perimeter is:

Perimeter P = 2( length + width )

Perimeter P = 2( ( 3x - 5 ) + 4x )

Add like terms:

Perimeter P = 2( 3x + 4x - 5 )

Perimeter P = 2( 7x - 5 )

Perimeter P = 14x - 10

Therefore, the perimeter is 14x - 10.

The number of possible values for m is 3.

An integer a is its own inverse mod m if a * a^(-1) = 1 (mod m)

For the first condition, 9 is its own inverse mod m, 99^(-1) = 1 (mod m)

so 99^(-1) = 1 + km for some integer k.

so 9*9^(-1) - 1 = km

so 8 = km

so m must be a divisor of 8.

For the second condition, 3 is not its own inverse mod m, 33^(-1) ≠ 1 (mod m)

so 33^(-1) = 1 + km for some integer k, k ≠ 0

so 3(3^(-1) - 1) = km

so 3(3^(-1) - 1) = km

so 3(1 - 3^(-1)) = km

so 3(1 - 9^(-1)) = km

so 3(8 - 9^(-1)) = km

so 38 - 39^(-1) = km

so 24 - 39^(-1) = km

so 24 - 27^(-1) = km

so 24 - 27^(-1) = km

so -327^(-1) = km

so -33^(-1) = km

so -33^(-1) = km

so 33^(-1) - 1 = km

so 33^(-1) = 1 + km

so 3*3^(-1) ≠ 1 (mod m)

The only positive integers that divide 8 are 1,2,4 and 8. Out of these, only 8 is not a solution. So the number of possible values for m is 3.

Therefore, The number of possible values for m is 3.

Relief refers to the highest and lowest point elevation in an area.

Relief

Relief is the term used for the differences in height from place to place on the land’s surface and it is greatly affected by the underlying geology. Relief relies on the hardness, permeability and structure of a rock.

elevation

The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface.

geology

Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks.

The expressions that will give you a difference of 5 are: -3 - (-8) and 1 - (-4).

The difference of two expressions is determined by subtracting one from the other.

Find the difference of each of the expressions given to determine which will give us 5.

-3 - (-8)

= -3 + 8

= 5

-2 - 3 = -5 [this is not the same as 5]

1 - (-4)

= 1 + 4

= 5

A triangle can be named based on its angles as follows:

Acute Triangle: A triangle where all three angles are less than 90 degrees is called an acute triangle.

Obtuse Triangle: A triangle where one angle is greater than 90 degrees is called an obtuse triangle.

Right Triangle: A triangle where one angle is exactly 90 degrees is called a right triangle.

a. The set of lengths 5 cm, 6 cm, and 7 cm will form a triangle because the sum of the two smaller sides is greater than the largest side. Since 5² + 6² < 7², the triangle will be obtuse.

b. The set of lengths 2 cm, 11 cm, and 15 cm will form a triangle because the sum of the two smaller sides is greater than the largest side. Since 2² + 11² < 15², the triangle will be obtuse.

c. The set of lengths 10 cm, 15 cm, and 20 cm will form a triangle because the sum of the two smaller sides is greater than the largest side. Since 10² + 15² > 20², the triangle will be acute.

d. The set of lengths 10 cm, 24 cm, and 26 cm will form a triangle because the sum of the two smaller sides is greater than the largest side. Since 10² + 24² < 26², the triangle will be obtuse.

e. The set of lengths 1 cm, 3 cm, and 9 cm will not form a triangle because the sum of the two smaller sides is not greater than the largest side.

c. R ∪ S = {(a, b), (a, d), (a, c), (b, c), (c, c), (d, a), (b, d)}

d. S - R = {(a, c), (b, d)}

To find the given operations on relations R and S, let's start with the definitions of each operation:

a. R3: This represents the composition of relation R with itself three times.

To find R3, we need to perform the composition operation on R three times:

R3 = R ∘ R ∘ R

Calculating R ∘ R:

R ∘ R = {(a, c), (a, a), (b, a), (c, c), (d, b), (d, d)}

Now, let's calculate R ∘ R ∘ R:

R ∘ R ∘ R = R ∘ (R ∘ R)

= R ∘ {(a, c), (a, a), (b, a), (c, c), (d, b), (d, d)}

= {(a, a), (a, b), (a, c), (a, d), (b, a), (b, b), (b, c), (c, a), (c, b), (c, c), (d, a), (d, b), (d, d)}

Therefore, R3 = {(a, a), (a, b), (a, c), (a, d), (b, a), (b, b), (b, c), (c, a), (c, b), (c, c), (d, a), (d, b), (d, d)}.

b. $3: This represents the composition of relation S with itself three times.

To find S3, we need to perform the composition operation on S three times:

S3 = S ∘ S ∘ S

Calculating S ∘ S:

S ∘ S = {(a, a), (a, d), (b, a), (d, c)}

Now, let's calculate S ∘ S ∘ S:

S ∘ S ∘ S = S ∘ (S ∘ S)

= S ∘ {(a, a), (a, d), (b, a), (d, c)}

= {(a, a), (a, c), (a, d), (b, a), (b, c), (b, d), (d, a), (d, c)}

Therefore, S3 = {(a, a), (a, c), (a, d), (b, a), (b, c), (b, d), (d, a), (d, c)}.

c. R ∪ S: This represents the union of relations R and S.

R ∪ S = {(a, b), (a, d), (a, c), (b, c), (c, c), (d, a), (b, d)}

d. R ∩ S: This represents the intersection of relations R and S.

R ∩ S = {(d, a)}

e. S - R: This represents the set difference of relation S and relation R.

S - R = {(a, c), (b, d)}

Therefore:

a. R3 = {(a, a), (a, b), (a, c), (a, d), (b, a), (b, b), (b, c), (c, a), (c, b), (c, c), (d, a), (d, b), (d, d)}.

The volume of the given triangular prism is 192 cubic centimeters.

To find the volume of a triangular prism, we need to multiply the area of the base triangle by the height of the prism. In this case, the base of the triangle has a length of 12 cm and an altitude of 8 cm. Thus, the area of the base can be found using the formula for the area of a triangle, which is (1/2) x base x height.

Area of base triangle = (1/2) x 12 cm x 8 cm = 48 cm²

The height of the prism is given as 4 cm. Therefore, we can now find the volume of the prism by multiplying the area of the base by the height of the prism.

Volume of triangular prism = area of base x height of prism = 48 cm² x 4 cm = 192 cm³

The fuel price increase for Namibia from 05/06/2019 to 01/03/2021 is 0.08 US dollars.

To calculate the fuel price increase for Namibia from 05/06/2019 to 01/03/2021, we need to subtract the fuel price on 05/06/2019 from the fuel price on 01/03/2021.

Fuel price increase = Fuel price on 01/03/2021 - Fuel price on 05/06/2019

Given the fuel prices in US dollars for Namibia:

Fuel price on 05/06/2019 = 0.80 US$

Fuel price on 01/03/2021 = 0.88 US$

Fuel price increase = 0.88 US$ - 0.80 US$

= 0.08 US$

Therefore, the fuel price increase for Namibia from 05/06/2019 to 01/03/2021 is 0.08 US dollars.

The equation of the line passing through the point ( -7,-6) will be y = x + 1.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

Given that the line that passes through the point (-7, -6) and is

A function assigns the value of each element of one set to the other specific element of another set.

Given that the linear function, f(x)=2x is needed to be reflected across the y-axis, therefore, the reflected function can be found by multiplying the function by -1. Therefore, the reflected function will be,

Answer:

Paint set cost = 10.5 , Sketch book cost = 7 , Brush cost = 1.75

Step-by-step explanation:

Let the cost of paint set be = p

Cost of sketchbook 's' = (2 / 3) p

Cost of brush 'b' = 1/4th of s = 1 / 4 [ (2 / 3) p ] = (1 / 6) p

Total expenditure = Money bought - Money left = 23.25 - 4 = 19.25

Total expenditure = Cost of (pen + of sketchbook + of brush) = p + s + b

= p +  (2 / 3) p + (1 / 6) p  = 19.25 → p + 2p / 3 + p / 6 = 19.25

( 6p + 4p + p ) / 6 = 19.25 → 11p / 6  = 19.25 →  p = ( 19.25  x 6 ) / 11

p = 10.5 ; s = (2 / 3) p  = 2 / 3 (10.5) = 7 ; b = (1 / 6) p  = 10.5 / 6 = 1.75
