Answer:
Step-by-step explanation:
<em>1).</em>
(a). Yes, the graph is linear.
(b). Rate of change is a slope m, m = (60 - 80) / (10 - 0) = - 2
<em>2).</em> Graph is not proportional, because y-intercept is (0, 80) and not (0, 0)
If you would like to find the difference (6y^3 + 17y - 3) - (4y^3 - 11y + 9), you can do this using the following steps:
(6y^3 + 17y - 3) - (4y^3 - 11y + 9) = 6y^3 + 17y - 3 - 4y^3 + 11y - 9 = 2y^3 + 28y - 12
The correct result would be 2y^3 + 28y - 12.
Answer:
The expression seems to be bugged.
Step-by-step explanation:
Based on how it says null, there is probably something wrong with the program you are using. You should contact your supervisor or teacher or whatever, it might have bugged.
Answer:
The best rational approximation for the square root of 55 is 7.5.
Let me know if this helps!
The slope is plus two. This graph is going to go from quadrant 3 to quadrant 1. That means it is neither horizontal or vertical. I've enclosed the graph to show you what it does. I think you want tilted right upwards. I can guarantee tilted.
Tilted right upwards <<<<<< answer
