Hello!
To solve exercise 9, we must use the rule of three.
Note that the initial price was R12 (corresponds to 100%).
The new price is R10.8 (we'll consider x%).
Using the rule of three, we will have:
Now, let's calculate the difference between the initial percentage and the new percentage:
<h2>Answer:</h2>
10% of decrease.
Answer:
Step-by-step explanation:
X=-1/2
Hope this helps mark me as brainiest pls
Answer:
4 = 1x
Step-by-step explanation:
(3x)9 = (4x)5
9 = (1x) 5
4 = 1x
Therefore, the best and most correct answer among the choices provided by the question is the fourth choice "15 - 2x ≥ 4y". I hope my answer has come to your help.
Using translation concepts, it is found that the image of point R after the transformations is given by: (1,-2).
<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 in it's definition.
The first transformation is:
(x,y) -> (x - 3, y + 5).
Hence:
(2,-3) -> (-1, 2).
For the rotation of 180º counter clockwise, the rule is:
(x,y) -> (-x,-y).
Hence the image is:
(-1,2) -> (1,-2).
