Answer:
Step-by-step explanation:
- 5x² - 20x + 15 = 0
- x² - 4x + 3 = 0
- x² - 4x + 4 = 1
- (x - 2)² = 1
- √(x - 2)² = √1
- x - 2 = ± 1
- x = 2 ± 1
- x = 1, x = 3
For this case we have a function of the form:
Where,
n0: initial amount (in units of millions)
b: growth rate
t: time in years
Substituting values we have:
Answer:
the number of toys being produced, n (in millions), in t years is:
D.

Answer:
<h3>X=-1/8=-0.125</h3>
Step-by-step explanation:
Isolate x on one side of the equation.
x+2/4=3/8
2/4=1/2 (First, use the common factor of 2.)
x+1/2=3/8
x+1/2-1/2=3/8-1/2 (Then, subtract 1/2 from both sides.)
3/8-1/2 (Solve.)
3/8-1/2=-1/8
-1/8=-0.125
x=-1/8=-0.125
In conclusion, the final answer is x=-1/8=-0.125.
