Answer:
B. 4,1
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
Divide both sides by -3, and replace with . Then
Factorize the quadratic in to get
which in turn means
But for all real , so we can ignore the first solution. This leaves us with
If we allow for any complex solution, then we can continue with the solution we ignored:
Answer:
4
Step-by-step explanation:
The x-intercept occurs when y=0, if you think about it graphically. Plug y=o into your equation:
10x - 5(0) = 40
10x = 40 (divide each side by 10)
x=4
The answer is 9 because the difference in this sequence goes +1,+2,+3 etc. So all you have to do is plus 6 to 15 and you get 9.
