F(x)= 650(1+.12)^x
f(x) = 650(1.12)^x
The 5x and the combination of (40° + x) are "vertical angles".
Vertical angles are equal.
So
5x = 40° + x
Subtract 'x' from each side: 4x = 40°
Divide each side by 4 : x = ?
Answer:
4/5
Step-by-step explanation:
<u>4/5 = 80%</u>
1/4 = 25%
3/10 = 30%
Answer:
Any value of "x" makes the equation true
Step-by-step explanation:
(-∞,∞)
All real numbers
