Answer:
47 is greater than or equal to 5x+10y
Step-by-step explanation:
you can't spend more than $47 but you can spend less than or equal to that amount.
To determine or predict the expected number of sales after 2 years, we substitute 2 to the t of the givne equation.
N = (8800)xln(7(2) + 9)
N = 27,592.34
Thus, it is expected that the number of sales after 2 years is 27,592 units.
Answer:
x = 400 when y = 100
Step-by-step explanation:
This is a question in relation to direct variation.
y ∝ 
y = k
Given that, y = 45, x = 81. Then;
45 = k 
45 = 9k
k = 
k = 5
Thus the relationship among the variables is;
y = 5
If y = 100, then;
100 = 5
= 
= 20
x = 
x = 400
Therefore, x = 400 when y = 100.
Answer:
x = ±4i or x = ±√-16
Step-by-step explanation:
x² - 5x + 19 = 5x + 3
x² + 16 = 0
x² = -16
x = ±√-16 (a negative square root is an imaginary number)
