Graph the image of the figure using the transformation given.
options are the last 3 pictures
The figure with these coordinates are R'(0, -4), S'(2, 0), T'(3, 0) and U' (4, -1) given below. Therefore, option A is the correct answer.
Given that, the translation is 3 units right and 4 units down.
What is translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions. Since it is just moving the shape from one place to other, there is no change in the shape.
The coordinates of the given figure are R(-3, 0), S(-1, 4), T(0, 4) and U(1, 3).
If the translation is 3 units right and 4 units down, then the coordinates become (x+3, y-4).
That is, R'(-3+3, 0-4)=(0, -4)
S'(-1+3, 4-4)=S'(2, 0)
T'(0+3, 4-4)=T'(3, 0)
U'(1+3, 3-4)=U' (4, -1)
So, the coordinates are R'(0, -4), S'(2, 0), T'(3, 0) and U' (4, -1)
The figure with these coordinates are R'(0, -4), S'(2, 0), T'(3, 0) and U' (4, -1) given below. Therefore, option A is the correct answer.

By using the concepts of line segment and collinearity of line segments, the numerical length of the line segment JK within the line segment IK is 21 units.
How to determine the length of the line segment JK within the line segment IK
In this problem we find two collinear line segments IJ and JK, two line segments are collinear if they are contained by the same line. The mathematical expression that represents the two collinear line segments are shown below:
IJ + JK = IK
If we know that JK = x + 6, IJ = 9 and IK = 2 · x, then the numerical length of JK is:
9 + (x + 6) = 2 · x
x + 15 = 2 · x
15 = 2 · x - x
15 = x
x = 15
JK = x + 6
JK = 15 + 6
JK = 21

What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
The graph of the function f(x) = x, as an illustration is attached
The transformation of linear functions are:
Horizontal shifts;
f(x + h); A shift of h units left
f(x - h); A shift of h units right
Vertical shifts;
f(x) + m; A shift of m units up
f(x) - m; A shift of m units down
Whereby the y-intercept of f(x) is 0, we have;
Let f(x) = x, therefore;
g(x) = f(x) + 3
= x + 3

(a) Line AV and line RV(b) Plane SRZ, plane TRS, plane QTZ (c) Points S, R and Q(d) Points Q, T, R, and S(e) Line segment RV(f) Ray RA and ray RV======================================================
Explanation:
Part (a)
Pick any two points on line p. I'll go for points A and V. They lead to the name "line AV". The order doesn't matter so we could say "line VA"
Or you could pick points A and R to get line AR, and so on.
There are 6 different ways to name this line. We found 2 so far, and I'll let you find the other four.
-------------------------------
Part (b)
To name a plane, we need 3 points that reside in it. Points R, S and Z are in the vertical plane W. So we could call it "Plane SRZ". The order of the points doesn't matter.
-------------------------------
Part (c)
The term "collinear" means the points are on the same straight line. This applies to points S, R and Q. Also, it applies to points A, R, and V.
We cannot say something like "points S, R, and V are collinear" since they are on different lines. The points need to be on the same straight line.
-------------------------------
Part (d)
Coplanar points are part of the same plane. Pick your four favorite points in plane W that is shaded. You cannot select W since it's not a point.
-------------------------------
Part (e)
A line segment has a fixed length. Neither endpoint goes on forever. Technically there aren't any segments shown on this diagram since we have lines only. Though if we focus on a subset of say line AV, then segment RV is one possible line segment.
-------------------------------
Part (f)
Like with part (e), there are technically only lines here and nothing else. But we could break the line apart to get 2 rays.
A ray has one fixed endpoint and it points forever in one direction only. Think of a ray of light. An example of a ray is to start at point R and go forever toward point V. This forms ray RV. A similar situation happens with ray RA.
The order is important. The notation Ray RV is different from Ray VR since the first letter tells us the fixed endpoint that doesn't go on forever.
Notice how rays RV and RA, when joined together, form a straight line. They point in opposite directions. You could think of it like one is pointing north and the other points south.

Therefore, two other names for line p are:
[tex]\overleftrightarrow{AV}[/tex][tex]\overleftrightarrow{RV}[/tex]Part bA plane can be named by using three non-collinear points in the plane or by a (capital script) letter.
Therefore, three other names for plane W are:

The collinear points on the given diagram are: A, R & V, and S, R & Q.
Therefore, three points that are collinear are:

The coplanar points on the given diagram are: Q, R, S, T and Z

The line segments on the given diagram are:

[tex]\overrightarrow{RA} \; \textsf{and} \; \overrightarrow{RV}, \quad \overrightarrow{RS} \; \textsf{and} \; \overrightarrow{RQ}[/tex]

Consider two consecutive positive integers such that the square of the second integer added to 4 times the first is equal to 73.
Step 2 of 2 :
Find the integers by solving the equation.
The numbers are 6 and 7.
How to solve the equation?Let the values be x and x + 1.
Therefore, the equation will be:
4x + (x + 1)² = 73
4x + x² + 2x + 1 = 73
x² + 6x + 1 - 73 = 0
x² + 6x - 72 = 0
x² + 12x - 6x - 72
x(x + 12) - 6(x + 12)
Therefore, x - 6 = 0
x = 0 + 6 = 6
Therefore, the numbers are 6 and 7

Plot the points in the coordinate plane. Then determine whether AB and CD are congruent. Explain
Answer:
AB and CD are congruent.
Step-by-step explanation:
Given points:
A = (-4, 1)B = (-4, 8)C = (-2, -5)D = (5, -5)After plotting the given points (see attachment), we can easily determine that AB is 7 units and CD is 7 units. Therefore, AB and CD are congruent.
Alternatively, as points A and B share the same x-coordinate, the length of AB is the difference between the y-coordinates:
⇒ AB = 8 - 1 = 7 units
Similarly, as points C and D share the same y-coordinate, the length of CD is the difference between the x-coordinates:
⇒ CD = 5 - (-2) = 7 units
Finally, we can prove that AB and CD are congruent by calculating their lengths using the distance formula.
[tex]\boxed{\begin{minipage}{7.8 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two endpoints.\end{minipage}}[/tex]
[tex]\begin{aligned}\implies AB & =\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\& =\sqrt{(-4-(-4))^2+(8-1)^2}\\& =\sqrt{(0)^2+(7)^2}\\& =\sqrt{0+49}\\& =\sqrt{49}\\& =7\end{aligned}[/tex]
[tex]\begin{aligned}\implies CD & =\sqrt{(x_D-x_C)^2+(y_D-y_C)^2}\\ & =\sqrt{(5-(-2))^2+(-5-(-5))^2}\\ & =\sqrt{(7)^2+(0)^2}\\ & =\sqrt{49+0}\\ & =\sqrt{49}\\ & =7\end{aligned}[/tex]
Therefore, as AB = CD, this proves that AB and CD are congruent.
