Answer:
(a)
(b)
Total number of weeks is 8
Step-by-step explanation:
(a)
we are given
Chung has $10.00 in his coin jar
so, initial amount =$10.00
He plans to put $6.0 more into the jar every week
Let's assume number of weeks =x
so,
total money in jar after x week = (initial money) +(number of weeks)*(money put in every week)
so, we get
Total money in jar after x week is
(b)
we are given
Chung has $58
so, we can set M=58
and then we can solve for x
Subtract both sides by 10
Divide both sides by 6
and we get
So,
Total number of weeks is 8
Y^=323.905•0.875x because it is the correct answer
9514 1404 393
Answer:
Step-by-step explanation:
For function ...
sometimes we know y, but we want to find the corresponding value x. That is, we would like to have an inverse function:
Here, I have said the input to the inverse function is the value of y for which we want the corresponding value of x.
__
Normally, we write the inverse function basically the same way we write the function. The input is named x, and the output is named y. We can swap the variable names for input and output either before or after we find the equation that relates them.
Perhaps you can see that finding the inverse function
amounts to solving the function relation y = f(x) for x. If we interchange variables first, it is the same as solving x = f(y) for y.
__
To find the inverse, we can interchange the variables and solve for y.
_____
The graph of the inverse of a function is the reflection of the graph of the function across the line y=x. The given function and the inverse we found are graphed in the attachment. The dashed line is y=x.
Answer:
x = 17
Step-by-step explanation:
These are same side interior so they equal different measures. You would write the equation like this.
8x - 9 + 53 = 180 (collect like terms)
8x + 44 = 180 (minus 44 on both sides)
8x = 136 (divide by 8 on both sides)
x = 17
