A coin bank has 250 coins, dimes and quarters, worth $39.25. How many of each type of coin are there?

Brilliant_brown [7]

$x-\ number\ of\ dimes\\y-\ number\ of\ quarters\\\\ \left \{ {{x+y=250\ \ \ | x=250-y} \atop {0.1x+0.25y=39.25\ \ \ \ \ \ \ \ \ \ \ \ \ }} \right. \\\\ substitution\ method\\\\
0.1(250-y)+0.25y=39.25\\\\
25-0.1y+0.25y=39.25\\\\
25+0.15y=39.25\ \ \ \ | subtract\ 25\\\\0.15y=14.25\ \ \ \ | divide\ by\ 0.15\\\\y=95\\\\x=250-95=
155\\\\

Which point below is not on the graph of p(x) = +36- X?

natka813 [3]

Answer:

We have the following equation: y = 36 - x. And we need to find which of the following points belong to the graph:

(-13,7)

(-35, 1)

(11,5)

(27,3)

If any of the points belong to the equation, then the equality will be met.

Then:

(-13,7) :

7 = 36 - (-13)

7 = 36 + 13

7 = 49 ❌

(-35, 1) :

1 = 36 - (-35)

1 = 71❌

(11, 5) :

5 = 36 - 11

5 = 25 ❌

(27,3)

3 = 36 - 27

3 = 9 ❌

None of the points belong to the graph. Therefore, all points are NOT on the grah of p(x) = 36 - x.
