Answer:
16.6
Step-by-step explanation:
a = 14
b = 9
c = x
a² + b² = c²
14² + 9² = x²
196 + 81 = x²
x² = 277
x = 16.6
"What percent" is our unknown x, "of" means we will multiply, "is" means equals. We set up the equation accordingly: x(12.5) = 39. 12.5x = 39. Divide both sides by 12.5 to get x = 3.12. To get to the percent form we multiply by 100 to get 312%.
The answer to this is C. (28,10) and (22,2).

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