If an ordered pair is reflected on x-axis, it will result in opposite number of y. If the original y positive, the reflected point of y will be negative.
we can write it as
(x,y) -> reflected to x axis -> (x, -y)
Solution:
(x,-y) = (4.75, -2.25)
(x,y) = (4.75, 2.25)
The original point was (4.75, 2.25)
0.05n + 0.1d = 4.75
<span>d = 2n </span>
<span>0.05n + 0.1(2n) = 4.75 </span>
<span>0.25n *100 = 4.75 8100 </span>
<span>25n = 475 </span>
<span>25n/25 = 475/25 </span>
<span>n = 19 </span>
<span>d = 2n </span>
<span>d = 2(19) </span>
<span>d = 38
</span>
<span>dimes = 38 </span>
<span>nickels =19</span>
Answer:
Step-by-step explanation:
This boils down to simple algebraic manipulation.
So one possible ODE (the simplest, in fact) is
