Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 3x + 5
g(x) = x²
(f - g)(x) is f(x) - g(x)
<u>Step 2: Find (f - g)(x)</u>
- Substitute: (f - g)(x) = 3x + 5 - x²
- Rewrite: (f - g)(x) = -x² + 3x + 5
X = 75% * y
Where 'x' is the single tennis court width, and 'y' is the doubles tennis court width.
Plug in what we know:
27 = 75% * y
75% = 0.75
27 = 0.75 * y
27 = 0.75y
Divide 0.75 to both sides:
y = 36
So the doubles court is 36 feet wide.
The problem is 3+6x = 15 with x being the number of white numbers.
Isolate variable by subtracting 3 on both sides: 6x = 12.
Isolate variable by dividing 6 on both sides: x = 2
The number of white marbles is 2.
