Translation

Rigid motion occurs when you move figures without affecting the size or shape in order for the figure to be congruent in a new location.

The types of rigid motions are:

In this problem, you haven't provided any figure, but I've attached one below. As you can see, we have a triangle ΔABC that has been translated to a new location in order to match triangle ΔDEF. So any point (x, y) on the triangle is mapped following this rule:

[tex](x,y) \rightarrow (x+8,y+2)[/tex]

So the new vertices D,E,F will be:

[tex]A(-6,2) \rightarrow D(-6+8,2+2)=\boxed{D(2,4)} \\ \\ B(-6,6) \rightarrow E(-6+8,6+2)=\boxed{E(2,8)} \\ \\ C(-2,2) \rightarrow F(-2+8,2+2)=\boxed{F(6,4)}[/tex]

Answer:

a. 10x + 2y = 23

b. 4x - y + 3 = 0

c. y + 8 = 0

d. 2x - y + 4 = 0

Step-by-step explanation:

a.

Slope of the line 'm' is [tex]\frac{36.5-1.5}{-5-2}[/tex] = [tex]\frac{35}{-7}[/tex] = -5

Equation of the line with slope m and passing through the point (x₁,y₁) is y-y₁ = m·(x-x₁)

⇒y-1.5 = -5·(x-2)

⇒y = -5x + 10 + 1.5

⇒5x + y = 11.5 (or) 10x + 2y = 23

b.

Slope of the line 'm' = 4

Equation of the line with slope m and passing through the point (x₁,y₁) is y-y₁ = m·(x-x₁)

⇒y-15 = 4·(x-3)

⇒y = 4x -12 + 15

⇒4x - y + 3 = 0

c.

Line is parallel to y = 1

Equations of parallel lines only differ by constant. So the required line equation has the form y = c where c is any real number.

But, it is given that the line passes through the point (3,-8)

⇒c=-8

⇒y = -8 (or) y + 8 = 0

d.

Equation of a line with slope 'm' and y-intercept of (0,c) is of the form y = mx + c

⇒y = 2x + 4

⇒2x - y + 4 = 0

Answer:

1,170,000

Step-by-step explanation:

The returns are 15% of 1,300,000.

15% of 1,300,000 = 15% * 1,300,000 = 0.15 * 1,300,000 = 195,000

In 1 month, 195,000 smartphones were returned.

In 6 months, 6 times as many smartphones were returned.

6 * 195,000 = 1,170,000

Answer: 1,170,000

Answer:

1,170,000 Smartphones were returned over a 6-month period.

Step-by-step explanation:

Ok, so to start off, 15% of 1,300,000 is 195,000. Now if everything remains the same over the next 5 months, you just need to multiply the 195,000 by 6 to get the 6 month return rate. This results in the number of 1,170,000 Smartphones Returned over a 6-month period.

The bakery made 3 batches of cookies and a total of 180 cookies.

To determine the number of batches of cookies the bakery made, we divide the total amount of flour used by the amount of flour used in each batch. The bakery used 5.25 cups of flour in total, and each batch requires 1.75 cups of flour. Therefore, the number of batches made is:

[tex]\[ \text{Number of batches} = \frac{\text{Total flour used}}{\text{Flour per batch}} = \frac{5.25}{1.75} \][/tex]

[tex]\[ \text{Number of batches} = 3 \][/tex]

Since there are 5 dozen cookies in each batch, we multiply the number of batches by the number of cookies per batch to find the total number of cookies made:

[tex]\[ \text{Total number of cookies} = \text{Number of batches} \times \text{Cookies per batch} \][/tex]

[tex]\[ \text{Total number of cookies} = 3 \times (5 \times 12) \][/tex]

[tex]\[ \text{Total number of cookies} = 3 \times 60 \][/tex]

[tex]\[ \text{Total number of cookies} = 180 \][/tex]

Thus, the bakery made 3 batches of cookies, resulting in a total of 180 cookies."

New equations for a system can be written by interacting (adding or subtracting) the given equations, using substitution to insert an equation into another, or scaling an equation by multiplying it by a constant.

https://brainly.com/question/21620502

#SPJ12

Final answer:

To create equivalent systems of equations, one can use scaling to multiply an equation by a non-zero constant, substitution to replace variables with equivalent expressions, or elimination through addition or subtraction to reduce the number of variables.

Explanation:

When dealing with a system of equations, there are several methods to create equivalent systems, which effectively means rewriting the equations without changing the solution set. One common approach to achieve this is by using the following techniques:

Scaling: Multiplying an entire equation by a non-zero constant. This changes the coefficients but not the solutions.

Substitution: Replacing one variable with an equivalent expression derived from another equation in the system.

Elimination (Addition or Subtraction): Adding or subtracting equations from each other to eliminate one of the variables, effectively reducing the number of variables to solve for.

These methods allow us to simplify complex systems or prepare them for other solving techniques, such as matrix inversion or graphical representation.

Answer:

4200

Step-by-step explanation:

In an arithmetic sequence equation t=a + (n-1)d, a is the starting value. In this case, a=3000.

Although, since the initial investment is not considered the first month, the equation is t = a + dn.

d is the rate of change. In this case, the rate of change is 100 for every month, n.

Substitute these values from the problem to get an equation:

t = 3000 + 100n

t means the total amount of money we have for the amount of months (n) that passed.

Sub n for 12.

t = 3000 + 100n

t = 3000 + 100(12)

t = 4200

You will have $4200 after 12 months of investment.

[tex]x\leq -27[/tex]

Step-by-step explanation:

Given:

[tex]\frac{x}{-9}\geq 3[/tex]

Multiplying both sides by -9, we get

[tex]-9\times \frac{x}{-9}\leq -9\times 3\\x\leq -27[/tex]

On multiplying both sides of an inequality by a negative number, the sign of the inequality changes as evident in the above equation.

So, the value of [tex]x[/tex] varies as:

[tex]x\leq -27[/tex]

Answer:

(B) The inequality that represents this relationship is [tex]3x  < x^2 +15[/tex]

Step-by-step explanation:

Let us assume the given number = x

⇒ 3 times the given number = 3 (x)  = 3x

Square of the given number = [tex](x)^2  = x^2[/tex]

Now, According to the question:

The difference of (3 x) and 15 is no less than [tex] x^2[/tex]

⇒ [tex]3x - 15 < x^2\\ \implies 3x  < x^2 +15[/tex]

or, [tex]3x  < x^2 +15[/tex]

Hence, the given inequality is represented as [tex]3x  < x^2 +15[/tex]

Answer:

3x - 15 > [tex]x^{2}[/tex]

Step-by-step explanation:

Let the number be x

⇒3 times the number is 3x and square of the number is [tex]x^{2}[/tex]

Difference of 3 times a number and 15 is 3x -15

⇒This difference is no less than the square of the number

⇒The difference is greater than or equal to square of the number

⇒ 3x - 15 ≥ [tex]x^{2}[/tex]

The inequality which shows the number of weeks, w, you need to save to be able to go on a trip is 25w + 200 ≥ 535.

Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.

Total amount needed to go for a trip to California = $535

Already saved amount = $200

You decide to save an additional $25 per week.

Let w be the number of weeks needed to save $25 to get the amount needed to go for trip.

These saved amounts must be at least $535 to go for trip.

The amount saved after w weeks is 25w

Total saved amount = 200 + 25w

This saved amount must be ≥ 535.

So the inequality is 200 + 25w ≥ 535.

Hence the inequality which represents the amount need to save to go for trip is  200 + 25w ≥ 535.

(1, - 2 )

Step-by-step explanation:

Given the 2 equations

y = - 4x + 2 → (1)

y = 6x - 8 → (2)

Substitute y = 6x - 8 into (1)

6x - 8 = - 4x + 2 ( add 4x to both sides )

10x - 8 = 2 ( add 8 to both sides )

10x = 10 ( divide both sides by 10 )

x = 1

Substitute x = 1 into (2) for corresponding value of y

ln|sec θ + tan θ| + C

Step-by-step explanation:

The integrals of basic trig functions are:

∫ sin θ dθ = -cos θ + C

∫ cos θ dθ = sin θ + C

∫ csc θ dθ = -ln|csc θ + cot θ| + C

∫ sec θ dθ = ln|sec θ + tan θ| + C

∫ tan θ dθ = -ln|cos θ| + C

∫ cot θ dθ = ln|sin θ| + C

The integral of sec θ can be proven by multiplying and dividing by sec θ + tan θ, then using ∫ du/u = ln|u| + C.

∫ sec θ dθ

∫ sec θ (sec θ + tan θ) / (sec θ + tan θ) dθ

∫ (sec² θ + sec θ tan θ) / (sec θ + tan θ) dθ

Answer:

1170

Step-by-step explanation:

In a function, each "x" can only have one "y" number. A relation can still be a function if a y-value has more than one x-value.

Answer:

11. a)

The relationship represented by the graph is a function because it passes the vertical line test (VLT). Any vertical line you pass through the graph, it only "hits" one spot on the graph. For a relation to be a function, each x-value can only have one y-value. This means no hour can have two different amounts of bacteria.

b)

If there were the same number of bacteria for two consecutive hours, the graph would still represent a function. In this case, two values for "y" will have more than one value for "x". Although, each x-value still only has one y-value, so it's still a function.
