Find the coordinates, which are (5,4) and (6,8)
Answer 5 for kid 12 for adult
Step-by-step explanation:
Answer:
<h2>204 units²</h2>
Step-by-step explanation:
It's a rectangle. Therefore the opposite sides are congruent.
We have the equation:
2x + 4 = 12 <em>subtract 4 from both sides</em>
2x = 8 <em>divide both sides by 2</em>
x = 4
Put the value of x to the expression 4x + 1:
4(4) + 1 = 16 + 1 = 17
Therefore we have the rectangle with dimesions 17 × 12.
The area of the rectangle:
A = (17)(12) = 204
Using translation concepts, the y-coordinate of R' will be of -10.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For this problem, the rule is given by:
(x,y) -> (x + 4, y - 7)
y -> y - 7 means that for the image, the 7 is subtracted from the y-coordinate of the pre-image. The y-coordinate of R is of -3, -3 -7 = -10, hence the y-coordinate of R' will be of -10.
