Answer:
Step-by-step explanation:
f(x)/g(x)=(6x+2)/(x-7)
The only restriction upon the domain, possible values of x, is division by zero is undefined. So x cannot equal 7.
So the domain is all real numbers except 7. In interval notation the domain is
x=(-oo, 7),(7, +oo)
Answer:
2/17
Step-by-step explanation:
What class coukd this possibly be for
1. Let A(a,b) be a point in the coordinate axis. The reflection of A with respect to the x-axis is the point A'(a, -b).
2. So the reflection of C(6, 4) is C'(6, -4)
3. Remark, a picture is always helpful when dealing with reflections.
Answer:
<em>Money in her purse is Rs. 500.</em>
<em></em>
Step-by-step explanation:
Let the money in her purse = Rs. ![x\\](https://tex.z-dn.net/?f=x%5C%5C)
Let the money in her Money box = Rs. ![y](https://tex.z-dn.net/?f=y)
As per question statement,
- Double the money in her purse (i.e.
) and add it to the amount in money box, she gets Rs. 1700.
........ (1)
- Triple the money in her purse (i.e.
) and add it to amount in money box (
), she gets Rs. 2200.
....... (2)
<u>To find: </u>Money in her purse = ? i.e. ![x=?](https://tex.z-dn.net/?f=x%3D%3F)
Let us solve for
using the two linear equations.
We can use substitution method here i.e. find value of one variable from one equation and then substitute that value in other equation.
Using equation (1), we get the value of
as follows:
![y=1700-2x](https://tex.z-dn.net/?f=y%3D1700-2x)
Now, let us put this value of y in equation (2) to find the value of
:
![3x+1700-2x=2200\\\Rightarrow x+1700 = 2200\\\Rightarrow x=2200-1700\\\Rightarrow x = Rs.\ 500](https://tex.z-dn.net/?f=3x%2B1700-2x%3D2200%5C%5C%5CRightarrow%20x%2B1700%20%3D%202200%5C%5C%5CRightarrow%20x%3D2200-1700%5C%5C%5CRightarrow%20x%20%3D%20Rs.%5C%20500)
