Answer:
Step-by-step explanation:
(6 + 4)(-12) =
10 * -12 =
-120 <==
<span>6x+9y = 10500
x+y = 1480
Using elimination I get:
6x + 9y = 10500
-6x-6y = -8880
Add the 2 equations and I get 3y = 1620
Divide both sides by 3 and I get y = 540
Substitute that back in to 6x+9y = 10500.
I get that 6x+9*540 = 10500
9 * 540 = 4860
Subtract 4860 from both sides and I get 6x = 5640
Divide both sides by 6 and I get x = 940
So there must have be 940 children and 540 adults</span>

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 4(x - 3)
f(9) is x = 9
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: f(9) = 4(9 - 3)
- Subtract: f(9) = 4(6)
- Multiply: f(9) = 24
