Answer:
7.
Step-by-step explanation:
9y+12=75
subtract 12 from 75
divide by 9y
Using a system of equations, it is found that initially Ada has $0.385.
For the system, we have that the variables are:
- x is Ada's amount.
- y is Betty's amount.
- z is Chris's amount.
- w is David's amount.
$45 total, hence:

Ada <u>gets 2 from Betty</u>, hence:



<u>Chris triples</u> his money and <u>David's</u> money is <u>cut by half</u> four of them have the same amount, hence:

Then:




Solving for w, we find Ada's initial amount.







Initially, Ada has $0.385.

Answer:
the minimum value of product is -8
Step-by-step explanation:
We have been given the function y = 2x-8 and we have to find the minimum value of the xy.
Plugging the value of y in the product

f(x) represents a upward parabola and we know that for a upward parabola, the minimum point is the vertex.
So in order to find the minimum value we find the y coordinate of the vertex of the parabola.
x-coordinate of the parabola is given by

y -coordinate of the parabola is

Hence, the vertex is (2,-8)
Therefore, the minimum value of product is -8
The equation is y= -1/3 x + 3
