Which of the following is(are) the solution(s) to 9|x-1|- -45?
OA. x=4,-6
OB. No Solution
OC. All values are solutions
OD. x=-4,6

[tex]f_x(0,0)[/tex] is the partial derivative of [tex]f[/tex] with respect to [tex]x[/tex] evaluated at the origin. By definition of derivative, this is the limit

[tex]\displaystyle f_x(0,0) = \lim_{x\to0} \frac{f(x,0) - f(0,0)}{x-0} = \lim_{x\to0} \frac{f(x,0)}x[/tex]

The system of equation  4x - 3y = 3and  -8x + 6y = -6 has no solution as they are parallel lines.

When two or more linear equations are there we call them a system of equations.

Given a system of equations 4x - 3y = 3...(i) and -8x + 6y = -6...(ii) this is solvable as the number of variables is not more than the number of equations.

Now to solve for x or y first we have to eliminate one of the varibales by any arithmetic operation.

By observing we conclude that if we multiply equation(i) by 2 and then add both of them the x variable will cancel out and we can solve for y which is

      8x - 6y =  6

(+)  -8x + 6y = -6

 ----------------------

As we can see here that both x and y are getting canceled therefore these two equations have no solution and hence they are parallel to each other(lines).

Answer:

∠1 and ∠7, ∠2 and ∠8

Step-by-step explanation:

Alternate exterior angles are on the exterior of the lines and on opposite sides of the transversal.

Answer:

Step-by-step explanation:

All you need is angles that are the same in each shape.

For example, all squares are similar. They all have 4 ninety degree angles.

All polygons with equal angles are similar. All regular hexagons have interior angles of 120 degrees.  So all regular hexagons are similar.

All regular octagons are similar. All regular octagons (8 sides) have interior angles of 135 degrees.

To get more, just look up the names of all regular polygons from 3 to 10. I've given you three of them.

The dimensions of the another rectangle is 2 cm and 4 cm.

According to the statement

We have to find that the perimeter of another rectangle.

So, For this purpose, we know that the

The perimeter of a shape is defined as the total length of its boundary.

From the given information:

The perimeter of a pool is 150 m. the rectangle at the right is a scale drawing of the pool. The length of each square on the grid represents 1 cm. draw another scale drawing of the pool using the scale 25 m to 2 cm.

Then

From the given rectangle,

Length of the rectangle = 5 cm

Width of the rectangle = 10 cm

Ratio of length : width = 1 : 2

Perimeter of the rectangle = 2(l + b)= 150 cm

l + b = 75 -----(1)

Since, l : b = 1 : 2

l/b = 1/2

b = 2l ------(2)

From equations (1) and (2),

l + 2l = 75

3l = 75

l = 25 m

Width 'b' = 2(25) = 50 m

Now we've to draw a rectangle with a scale = 25 : 2

Therefore, multiplier factor = 25/l = 25/2

l = 2 cm

Similarly,

50/w = 25/2

w = 4 cm

Now we are able to draw a rectangle with length = 2 cm and width = 4 cm.

So, The dimensions of the another rectangle is 2 cm and 4 cm.

The two numbers with the value of 9 in the first digit being 10 times the value of 9 in the second digit are 98 and 9.

The first number will be 9 and the second number will be 98.

In the second number, the 9 is in the tens position which means that it has the value of 90.

In the first number, the value of 9 is simply 9.

therefore,90 is 10 times the value of 9 which means that 9 and 98 satisfy the requirements.

The “tens” digit is the digit in the second place to the left of the decimal point. The tens digit of 42936.875 is “3”. The “tenths” digit is the digit directly to the right of the decimal point.Each digit is a different place value. The left digit is the tens' place. It tells you that there are 8 tens. The last or right digit is the ones' place which is 4 in this example

In our decimal number system, the value of a digit depends on its place, or position, in the number. Each place has a value of 10 times the place to its right. A number in standard form is separated into groups of three digits using commas.

The volume of the given figure is 267.95 mi³.

The given object is a sphere. A sphere is a three-dimensional object that has all its surface points at equal distances from the center. A sphere is round in shape.

The volume of an object is the amount of space in the three-dimensional object.  The radius of a sphere is a straight line from the circumference of the sphere to the center of the sphere.

Volume of a sphere = 4/3 × π × r³

Where:

π = pi = 22/7

r = radius = 4

4/3 x 22/7 x 4³ = 267.94667 mi³

267.95 mi³

The required line representing the rise and the run of the line is created.

And the slope of the line in its simplest form is 9/-18.

Given a line is represented on the graph.

we need to create lines representing the rise and run of the line.

To find the slope of the line we need to determine the rise and run of the line.

The slope of a line is defined as the rise divided by the run, or the ratio of the rise to the run. It gives information about a line's slope in the coordinate plane. Finding the slope between two separate places is comparable to calculating the slope of a line.

The coordinates of the points are:

(9,0) = (x₁ , y₁)

(₋9 , 9) = (x₂ , y₂)

we know that slope (m) = rise/ run

rise  = y₂ ₋ y₁

= 9 ₋ 0

= 9

run = x₂ ₋ x₁

= ₋9 ₋ 9

= ₋18

hence the slope is 9/₋18

The required slope of the line is 9/-18.

Since m(n(x)) = n(m(x)) = x, then m(x) and n(x) are inverse functions

The inverse of a function is a function that can reverse into another function.

If we have function f and g, and f f(x) = y, then g is the inverse of f if and only if g(y) = x

Also, if f is a function f⁻¹ is the inverse of x and ff⁻¹(x) = f⁻¹f(x) = x

Given the functions m(x) = x³ - 5 and n(x) = ∛(x + 5)

If m(x) and n(x) are inverse, then m(n(x)) = n(m(x)) = x

So, we proceed as follows

m(x) = x³ - 5

m(n(x)) = (∛(x + 5))³ - 5

m(n(x)) = x + 5 - 5

m(n(x)) = x + 0

m(n(x)) = x

Also,

n(x) = ∛(x + 5)

n(m(x)) = ∛(x³ - 5 + 5)

n(m(x)) = ∛(x³ - 0)

n(m(x)) = ∛(x³)

n(m(x)) = x

Since m(n(x)) = n(m(x)) = x, then m(x) and n(x) are inverse functions
