Answer:
Step-by-step explanation:
So when x and y, vary inversely, it means that the product of x and y will remain constant such that: 
. This means that the function can be defined as 
by dividing both sides by x. In this case x=12, and y=8, this means the constant is equal to 12 * 8 which is 96. So we have the equation: 
, which can be defined as
<h3>
<u>Explanation</u></h3>
- Given the system of equations.
- Solve the system of equations by eliminating either x-term or y-term. We will eliminate the y-term as it is faster to solve the equation.
To eliminate the y-term, we have to multiply the negative in either the first or second equation so we can get rid of the y-term. I will multiply negative in the second equation.
There as we can get rid of the y-term by adding both equations.
Hence, the value of x is 3. But we are not finished yet because we need to find the value of y as well. Therefore, we substitute the value of x in any given equations. I will substitute the value of x in the second equation.
Hence, the value of y is 4. Therefore, we can say that when x = 3, y = 4.
- Answer Check by substituting both x and y values in both equations.
<u>First</u><u> </u><u>Equation</u>
<u>Second</u><u> </u><u>Equation</u>
Hence, both equations are true for x = 3 and y = 4. Therefore, the solution is (3,4)
<h3>
<u>Answer</u></h3>
Answer:
240
Step-by-step explanation:
Gain=25%
Gain=selling price - cost price
Gain = ((selling price - cost price )× 100)/ cost price
25c=(4800-c)100
25c=480000-100c
125c=480000
cost price = 3840
second statement
The selling price was 4080
Cost price 3840
therefore
Gain=selling price - cost price
Gain = 4080-3840
=240
You have not provided the coordinates of the original points, therefore, I cannot give exact answers.
However, I can help you with the concept.
We are given that the translation rule here is:
(x,y) ................> (x+3 , y+2)
This means that:
x coordinate of the translated point can be obtained by adding 3 to the x coordinate of the original point
y coordinate of the translated point can be obtained by adding 2 to the y coordinate of the original point
Examples:
point (2,3) after translation would become (2+3 , 3+2) which is (5,5)
point (-1,0) after translation would become (-1+3 , 0+2) which is (2,2)
Hope this helps :)
