Answer:
x int (4,0)
y int (0, -6)
Step-by-step explanation:
First, you want to solve for the equation for this problem, would be:
0.05N + 0.10D = 20.50
While N = The amount of nickels, and D = The amount of dimes.
Since N = 164, and D = 123. It would add up to 287 coins. 164 + 123 = 287.
Now that you have the number for those two variables, solve the equation for when N = 164, and D = 123.
0.05N + 0.10D = 20.50
<span>0.05(164) + 0.10(123) = 20.50
</span><span>8.2 + 12.3 = 20.50
</span>20.50 = 20.50
So, there is 164 nickels, and 123 dimes for your answer.

2x10^2 is 200.
2x10^8 is 200000000
2x10^8 is 1000000 times larger that 2x10^2
Answer:
x = 2 and x = -1
Step-by-step explanation:
The zeroes of the function are found by setting g(x) equal to 0:
g(x) = (x - 2)(3x + 3) = 0
By the Zero Product Property, in order for this equation to be equal to 0, each of (x - 2) or (3x + 3) or both has to equal 0. So, set each equal:
x - 2 = 0
x = 2
3x + 3 = 0
3x = -3
x = -3/3 = -1
The zeroes are thus x = 2 and x = -1.
