The rule as a mapping for the translation of a rectangle is (x, y) → (x – 2, y + 7). Which describes this translation?

maksim [4K]

Answer:

The answer is a translation of 2 units to the left and 7 units up

Step-by-step explanation:

we know that

In the rule for the translation of a rectangle

(x, y) → (x – 2, y + 7).

the term (x-2) means a translation of 2 units to the left

the term (y+7) means a translation of 7 units up

Therefore,

The answer is a translation of 2 units to the left and 7 units up....

If you plot and connect these points P1(3,2) and P2(6,8) , what figure is Formed? What is the Direction?

Sergio [31]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the points

P1(3, 2)

P2(6, 8)

When we plot P1(3, 2) and P2(6, 8), we determine the line segment P1P2.

The direction of the segment is from P1 to P2.

Determining the length of the segment P1P2.

$\:l=\:\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

$=\sqrt{\left(6-3\right)^2+\left(8-2\right)^2}$

$=\sqrt{3^2+6^2}$

$=\sqrt{45}$

$=\sqrt{5}\sqrt{3^2}$

$=3\sqrt{5}$

Thus, the length of the segment is:

$\:\:\:l=3\sqrt{5}$

Determining the equation of a line containing the segment P1P2

Given the points

P1(3, 2)

P2(6, 8)

Finding the slope between P1(3, 2) and P2(6, 8)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(3,\:2\right),\:\left(x_2,\:y_2\right)=\left(6,\:8\right)$

$m=\frac{8-2}{6-3}$

$m=2$

Using the line point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = 2 and the point (3, 2)

$y-2=2\left(x-3\right)$

Add 2 to both sides

$y-2+2=2\left(x-3\right)+2$

$y=2x-4$

Thus, the equation of a line containing the line segment P1P2 is:

$y=2x-4$

Given f as described below.

Illusion [34]

Answer with Step-by-step explanation:

We are given that a function

$f:W\rightarrow W$

Assign each whole number to its largest place value digit.

$f(4)=4$

$f(14)=4$

$f(194)=9$

We have to find the value of x that makes the equation 7 a true statement.

When f(x)=7

Then, the possible values of x are 7,127,27,257,... .

Because f(7)=7

f(127)=7

f(27)=7

f(257)=7

Therefore, the value of x =7,127,257,27,..
