Answer:
x = -1.32
Step-by-step explanation:
I expect '--' means equals to '=' in your question
4(10x+6)--10(9x+9)
4(10x+6)=10(9x+9)
40x +24 = 90x +90
40x - 90x = 90 - 24
-50x = 66
x = -66/50
x = -1.32
Answer:
Inverse of a function
Step-by-step explanation:
If the x- and y-values in each pair of a set of ordered pairs are interchanged, the resulting set of ordered pairs is known as the inverse of a function.
For example, given the following function:
y = 2x
If x=0 → y= 0
If x=1 → y= 2
If x=2 → y= 4
Now, if we find the inverse of the function:
y = 2x → x = 2y → y = x/2
Now:
If x=0 → y= 0
If x=2 → y= 1
If x=4 → y= 2
Comparing both cases, you will notice that the ordered pairs are effectively interchanged.
I think The answer is 2920
