Triangle ABC has vertices at A(−3, 4), B(4, −2), C(8, 3). The triangle is translated 4 units down and 3 units left. Which rule represents the translation? After the translation, what are the coordinates of vertex C?
Answer: Correct answer is (x, y) → ( x − 3, y − 4); (5, −1)
Step-by-step explanation: Starting from point 8,3 we go down 4 on the y-axis (y-4)and stopping at -1 then we go left on the x-axis (x-3) stopping at 5.
So the new coordinate for the vertex C should read 5,-1.
After the translation , the coordinates of vertex C are ( 5 , -1 )
Further explanationThere are several types of transformations:
TranslationReflectionRotationDilationLet us now tackle the problem!
This problem is about Translation.
The triangle is translated 4 units down and 3 units left.
The rule that represents the translation will be [tex]\left[\begin{array}{ccc}-3\\-4\end{array}\right][/tex]
Let's find the translation for every vertice of Triangle ABC:
A(-3 , 4) → A'(-3 + (-3) , 4 + (-4)) = A'(-6 , 0)
B(4 , -2) → B'(4 + (-3) , -2 + (-4)) = B'(1 , -6)
C(8 , 3) → C'(8 + (-3) , 3 + (-4)) = C'(5 , -1)
From the results above, we can illustrate the translation process as shown in the attached picture
Conclusion:After the translation , the coordinates of vertex C are ( 5 , -1 )

Why do u think rates are usually written as unit rates
The rate usually written for the amount of things is changing in one unit.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
A rate in mathematics is the comparison of two related values expressed in different units. The numerator of the ratio indicates the rate of change in the other (dependent) factor if the base of the ratio is written as a cohesive block of one of these variables, and if it is assumed that this quantity may be modified systematically (i.e., is an independent variable).
The rate usually written for the amount of units anything in one unit of something.

Defined by two lines or rays diverging from a common point.
A) arc
B) angle
C) parallel lines
D) perpendicular lines
Defined as bounded by two distinct end points that contain every point on the line between its end points.
A) circle
B) line segment
C) parallel lines
D) perpendicular lines
1. B angle
2. B line segment
Further explanationLet see the answer choices :
1 .
A) arcis part of the circumference of a circle
B) angleAngles can be formed from two ray lines that have the same starting point
Commonly used terms include foot angle, corner point, and angle size
The magnitude of the angle is usually expressed in degrees
Naming angles can be with one letter according to the vertex or with three letters with the vertex placed between two other letters
C) parallel linestwo lines that don't intersect each other at any point
D) perpendicular linesthe two lines intersect at a right angle.
So two lines or rays are diverged from a common point: angle
2 .
A) circleCircles are two-dimensional builds which are sets of equidistant points at a point called the center point
The distance of these points to the center is called the radius of the circle
B) line segmentThe line connecting two points and these two points is end points
C) parallel linestwo lines that don't intersect each other at any point
D) perpendicular linesthe two lines intersect at a right angle.
so bounded by two distinct end points that contain every point on the line between its end points: line segment

how can you tell that a line segment connecting two points is vertical without graphing the points
A line segment connecting two points is vertical without graphing the points are intersecting lines if they are not parallel.
What is a line segment?A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).
For the Parallel lines, it must have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.
Since the given parallel line has equation y = 5x + 2, thus its slope is 5 and thus, the slope of the needed line is 2 too.
They are intersecting lines if they are not parallel. therefore, the other option is that they are intersecting.

The original price of a watch was $550. During a mid year sale, the selling price was $440. Find the percent discount
Final answer:
The percent discount for the watch is 20%.
Explanation:
To find the percent discount on the watch, we first calculate the difference in price between the original price and the sale price.
Subtract the sale price ($440) from the original price ($550) to get the discount amount: $550 - $440 = $110. Next, to calculate the percent discount, we divide the discount amount by the original price and then multiply the result by 100 to convert it to a percentage.
Percent Discount = ($110 / $550) × 100 = 20%
Therefore, the watch was sold at a 20% discount during the mid year sale.
