Let Taylor's earnings be t, Andile's earnings be a and that of Favour be f.
Given that t+a+f=380. Also given that Taylor earned 40 less than Andile. That translates to t=a-40. Favour earned twice as much as Taylor.
That is, f=2t. Substitute t=a-40 into f=2t to get f=2(a-40)=2a-80.
Substitute t=a-40 and c=2a-80 into t+a+f=380 to get
a-40+a+2a-80=380.
Combining like terms, we get 4a-120=380. Adding 120 to both sides of the equation, we get, 4a=500 and dividing by 4 on both sides, we get a=125.
Since we want to know what Taylor earned, substitute a=125 back into t=a-40=125-40=85
Therefore, Taylor earned $85!
4 plus negative 3 is 1.
When adding negative numbers to positive ones, you should treat it as a normal subtraction, so 4-3.
Independent variable: The number of houses Harold sells
Dependent Variable: The amount of money Harold earns
Function: f(x)=250,000(x)
x represents how many houses Harold sells, and f represents how much money Harold earns.
Now, let's solve the problem.
f(x)=250,000(9)
f(x)=2,250,000
Harold earns $2,250,000
Coin 1 is Q, the very top coin is N and the one below that is Q. For the bottom coin 2 that's N and the very bottom is also N and the one on top of the very bottom is Q. I hope that helped!

So the formula is: (x-h)^2+(y-k)^2=r^2
(x-11)^2+(y+9)^2=144
