The image of the given triangle after transformation that has the rule (x,y)→(x,−y) is graphed below .

In the question

the triangle is given ,

From the figure , we can see that the coordinates of the triangle are

(2,7) , (4,-3) , (-5,-2)

let us name the coordinates of the triangle as A(2,7) , B(4,-3) , C(-5,-2) .

applying the transformation , that has rule (x,y)→(x,−y)

Using this rule to find the new coordinates of the triangle A'B'C' .

when A= (2,7)

A' = (2,-7)

When B = (4,-3)

B' = (4,-(-3))

B' = (4,3)

When C = (-5,-2)

C' = (-5,-(-2))

C' = (-5,2)

So the coordinates of the triangle  A'B'C' is A' = (2,-7) , B' = (4,3) , C' = (-5,2) .

the image triangle A'B'C' is shown below

The relation of the function as a product are found for the long division as:  (n-2)×(6n - 16) + 0 = 6n² - 4n - 16

The following describes the relationship between such four parts:

Divisor x Quotient + Remainder = Dividend

From the given pictures write the value of each part;

Dividend  = 6n² - 4n - 16

Divisor = (n-2)

Quotient = 6n - 16

Remainder = 0

Thus, the relation becomes;

(n-2)×(6n - 16) + 0 = 6n² - 4n - 16

Thus, the relation of the function as a product are found for the long division.

A person will wait at least 1.8720 seconds before the wave crashes when the waves are crashing onto the beach every 4.8 second

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

[tex]P(X\leq x)[/tex] = x-a / b-a

Uniform distribution from 0 to 4.8 seconds.

This means that a=0 , b=4.8

61% of the time a person will wait at least how long before the wave crashes in?

This is the 100 - 61 = 39% percentile, which is x for which [tex]P( X\leq x)= 0.39[/tex] . So

[tex]P(X\leq x)= \frac{x-a}{b-a}[/tex]

x= 1.8720

Answer: we need the immage

Step-by-step explanation:

Value of 'a' for the given statement  the negative a minus four sevenths equals two thirds for a after solving is equal to negative 26 over 21.

As given in the question,

Given statement :

Negative a minus four sevenths equals two thirds for a

Represent the statement in equation form :

-a -(4 / 7) = ( 2 / 3 )

Solve by adding both the side ( 4 / 7 ) we get,

-a - (4 /7) + (4 /7) = (2/3) +(4/7)

⇒ -a = (2/3) + (4/7)

least common multiple of 3 and 7 is 21.

-a = ( 14 /21) + (12 /21)

⇒ -a = 26 /21

⇒ a = -26/21

Therefore, value of 'a' for the given statement  the negative a minus four sevenths equals two thirds for a after solving is equal to negative 26 over 21.

The graph is as follows: f(x) = 3ˣ

The graph f (x) is transformed into the graph g(x)

The points (-2, 2) and (-2) on the curve g(x) are (-1,4).

Let any point on f be (a,b) (x).

After translation, a brand-new curve, g(x), is obtained that is perpendicular to the line, asymptotically equal to y=1, or when y reaches 1, the graph is perpendicular to the x axis.

The graph of the translated curve is g(x)=y-1=3ˣ⁺² where g(x) = y = 3ˣ⁺²  + 1.

The value of the unknown angle is as follows:

An angle bisector or the bisector of an angle is a ray that divides an angle into two equal parts

Therefore, CH bisects ∠GCD.

Therefore, it divide ∠GCD into two equal halves.

GC bisect ∠BGD.

Therefore, it divides ∠BGD into two equal halves.

Hence,

m∠BGC = m∠CGF

Therefore,

m∠BGC  = 7x - 2

m∠CGF = 8x - 8

7x - 2 = 8x - 8

7x - 8x = -8 + 2

-x = -6

x = 6

Therefore,

m∠BGF = 7x -2 + 8x - 8

m∠BGF = 15x - 10

m∠BGF = 15(6) - 10

m∠BGF = 90 - 10

Therefore,

A coordinate plane, often referred to as a rectangular coordinate plane grid, is a two-dimensional plane created by the intersection of the Y-axis, a vertical line, and the X-axis, a horizontal line. An area of two dimensions made up of two number lines is known as a coordinate plane. It is created when a point termed the origin, where the X-axis and Y-axis cross, is reached. You may find points by using the numbers on a coordinate grid. Graphing points, lines, and many other things may all be done using a coordinate plane. It serves as a map and provides exact driving instructions.

Based on the fact that there are courses with 3 credits and 4 credits, with the total that a student can earn being 65 credits, the number of 3 credit courses that the student completed was 19 courses and the number of 4 credit courses was 2 courses.

Assuming that the number of courses worth 3 credits are denoted as x and the number of courses worth 4 credits are denoted by y, the system of equations would be:

3x + 4y = 65

x + y = 21 courses

Using substitution for y gives:

x + y = 21

y = 21 - x

The number of courses with 3 credits is:

3x + 4y = 65

3x + 4(21 - x) = 65

3x + 84 - 4x = 65

84 - 65 = 4x - 3x

1x = 19

x = 19 courses

Number of 4 credit courses is:

The number of miles he/she can drive with a budget of 150 dollars is 469 miles.

The car rental advertised a car for  $27.95 per day and $0.26 per mile.

If someone rents the car for 4 days and he has a budget of 150 dollars, the number of miles he can drive can be calculated as follows:

The equation used to represent the situation is as follows:

let

x = number of miles drove

Therefore,

150 = 27.95 + 0.26x

subtract 27.95 from both sides of the equation

150 - 27.95 = 27.95 - 27.95 + 0.26x

0.26x = 122.05

divide both sides by 0.26

x = 122.05 / 0.26

x = 469.423076923

x = 469 miles

Therefore, the number of miles he can drive is 469 miles.

The constant of proportionality in cups of water to minute is 80 cups/min

Here we have the proportional relation:

y = k*x

Where y is the number of cups and x the time in seconds, then:

y/x = k

Replacing the values we know:

y = 8 cups.

x = 6 seconds.

We can get the value of k, the constant of proportionality, but first, let's write the time in minutes.

x = 6 seconds

remember that 1 min = 60 sec, then:

6 sec = (6/60) min = 0.1 min

So the constant of proportionality is:

k = 8cups/0.1 min = 80 cups/min
