System of equations (yay) x=nickels y=dimes
1st x+y=70
2nd .5x+.10y=4.65
3rd Move decimal (multiply everything by 100) : 5x=10y=465
x+y=70
-x -x
y=70-x
(Substitute) 5x+10(70-x)= 465
(Distribute) 5x+700-10x=465
(Solve equation) -5x=-235 >>> x=47 >>>
Answer- 47 dimes and 23 nickels
Please let me know if I need to explain further (:
Answer:
The picture
Step-by-step explanation:
Use the supplementary theorem and corresponding theorem. :)
The slope is 2 and the y intercept is -5. Graph this line and shade above the line for the solution. :)

The graph has a y-intercept of 2 and is shifted to the right 6 from the parent function.
The parent function, y=√x, looks like a parabola laid on its side. We generally only consider the positive square root unless told otherwise. Since we have √(x-6) instead of just √x, the graph is shifted to the right 6 units. The +2 at the end of the equation shifts the graph up 2.
