When certain mapping in the plane has the following property: Each pair of points A and B is mapped to another pair or points A' B' such that quadrilateral AA'BB' is parallelogram, the transformation is reflection.

Each point in a figure is moved the same distance in the same direction using a type of transformation known as translation.

When a figure is translated, it is moved in any direction.

Flipping a figure over a line is called reflection.

Rotation is the process of turning a figure a specific amount around a point.

Explanation:

Draw two parallel number lines as shown in the diagram below. Make sure the numbers line up.

The first number line has the interval [0,7] which is the same as writing 0 ≤ x ≤ 7

We have closed circles at 0 and 7. Then there's shading in between those endpoints.

Similarly, the other interval [-2, 5] represents -2 ≤ x ≤ 5. It has shading between the closed circles at -2 and 5.

The red dashed lines represent the portions where the two number lines overlap. This is from x = 0 to x = 5

The sub-interval 0 ≤ x ≤ 5 is found in both domains, and hence it's the domain of f+g

That turns into the interval notation of [0, 5]

Answer: f(2)=-10     f(-3)=15

Step-by-step explanation:

Let the number conceived be x.

Hence,

f(x)=(x+5)(-3)-2x+15

f(x)=-3x-15-2x+15

f(x)=-5x

Thus,

f(2)=(-5)(2)

f(2)=-10

f(-3)=(-5)*(-3)

f(-3)=15

From drawing the graph of the function 3x + y = -5, we can tell that the x and y intercepts are respectively; x = -5/3 and y = -5

We are given the Linear equation as;

3x + y = -5

Now, the y-intercept of the function is the point where x = 0. Thus, we plug in 0 for x to get the y-intercept.

3(0) + y = -5

0 + y = -5

y = -5

Similarly, the x-intercept will be the point when y = 0. Thus, we plug in 0 for y to get the x-intercept;

3x + 0 = -5

3x = -5

x = -5/3

From drawing the graph of the function 3x + y = -5, we can tell that the x and y intercepts are respectively; x = -5/3 and y = -5

The value of the linear equation 12x+10=54-10x, X=22.

An algebraic equation of the form y=mx+b is referred to as a linear equation involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a linear equation of two variables, where y and x are the variables.

Given that,

Moira chooses 10x on the left side of the equation,

And on the right side she chooses 10x

Given equation is 12x+10=54-10x

12x+10-10=54-10x-10 (subtract -10 on both sides)

12x=44-10x

Answer:

s = [tex]\frac{5}{2}[/tex] in

Step-by-step explanation:

the volume (V) of a cube is calculated as

V = s³ ( s is the edge length )

given V = [tex]\frac{125}{8}[/tex] in³ , then

s³ = [tex]\frac{125}{8}[/tex] ( take cube root of both sides )

[tex]\sqrt[3]{s^3}[/tex] = [tex]\sqrt[3]{\frac{125}{8} }[/tex]

Some formulas related to AP are-

Now, for the stated sequence is: 10,20,30,40, ...........

Let us suppose the first term is'a₁' = 10.

Let us suppose 'a₂' = 20 is the second term.

Let us suppose the third term is 'a₃' = 30.

Let us suppose the fourth term be 'a₄' = 40.

d = a₂ - a₁      

Substitute the values;

d = 20 - 10 = 10       ........(equation 1)

Now consider the other set;

d = a₃ - a₂    

d = 30 - 20 = 10      .......(equation 2)

By substitution, the solution of the system of equations, 4p + 2q = 8 and q = 2p + 1, is (p , q) = (3/4 , 5/2).

A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.

There are three methods that can be used to solve system of linear equations.

1. Elimination

2. Substitution

3. Graphing

Using substitution method, given two linear equations in p and q,

4p + 2q = 8     (equation 1)

q = 2p + 1     (equation 2)

Since the second equation is already expressed in q in terms of p, substitute the second equation to the first equation.

4p + 2q = 8     (equation 1)

4p + 2(2p + 1) = 8

4p + 4p + 2 = 8

Combining all terms containing the variable p on one side and the constants on the other side of the equality, and solving for p.

4p + 4p + 2 = 8

4p + 4p = 8 - 2

8p = 6

p = 6/8

p = 3/4

Substitute the value of p in the second equation and solve for q.

q = 2p + 1

q = 2(3/4) + 1

q = 6/4 + 1

q = 5/2

Hence, the solution of the given system of equations is (p , q) = (3/4 , 5/2).

Geometric progression is a sequence of series whose ratio with adjacent values remains the same.

Orignal price iss 100
Appreciates 10% each year,
So price on next year = 100 + 100 * 10 / 100
So the price next year = 110
Similarly price on the next year becomes in a series = 100, 110, 121,
