Answer:
x=-4
Step-by-step explanation:
First, distribute the 4
this makes 4x + 36 = 20
Then, subtract 36 to combine like terms. 4x = -16
divide 4x! x = -4
Answer:
<em>x = 5/3 </em>or<em> x = -3</em>
Step-by-step explanation:
3x² + 4x - 15 = 0
Factor left side.
(3x - 5)(x + 3) = 0
Set factors equal to 0.
3x - 5 = 0
3x = 5
x = 5/3
x + 3 = 0
x = -3

Answer:
2/5m - 1/5
Step-by-step explanation:
Domain- all the x-values that can be plugged into the function/ applicable to the function<span>.
x-values in this case are measured in units of time(years) AFTER he deposited the amount</span><span>.
</span>
Therefore, we only have positive x-values because the yearly interest rate in this function is only applicable to a positive number of years<span>.
The bracket means including zero
The parentheses mean not including zero</span><span>.
Whenever the infinity symbol(</span>∞) is used it is always accompanied by a parentheses<span>.
</span>[0, ∞) is the answer because infinitely many positive number of years can be plugged into this function.
