6000 - 1800 = 4200
4200/4 = 1050
so she donated 25% to charity
Answer:
32 + x= 90
x= 90- 32 = 58
x + y = 90
38 + y= 90
y= 90-38
y = 52
Step-by-step explanation:
The function is positive when x is larger than 3, then the interval in where the function is positive is: (3, ∞)
<h3>
on what interval is the function positive?</h3>
The function is positive when g(x) > 0.
Then we need to solve:
∛(x - 3) > 0
We can directly remove the cubic root, because it does not affect the sign of the argument, then:
x - 3 > 0
x > 3
The function is positive when x is larger than 3, then the interval in where the function is positive is: (3, ∞)
