The answer is x=-2
As you could see, this is a factored function.
The un-factored version is x^2+4x-12
-b/2a=x
-4/2=-2= x of vertex
Answer:
They meet a line. Therefore, if two planes cut one another, then their intersection is a straight line.
Step-by-step explanation:
She has run 21 miles already. Let t be the number of additional miles added on.
In total, she has run t+21 miles
This is going to be set greater than 38 since "Ann will run more than 38 miles"
So we have this inequality
t+21 > 38
we solve for t by subtracting 21 from both sides
t+21 > 38
t+21-21 > 38-21
t+0 > 17
t > 17
The final answer is t > 17
which means that the possible additional number of miles she could run is anything larger than 17. So t = 18 is one possibility.
Answer: y = -3/4x
Step-by-step explanation:
the slope is -3/4
Answer:
The correct answer is 30
Step-by-step explanation:
Given: The x-axis represents the time in hours and the y-axis represents the distance in miles.
The line passes through the points
and 
To find: The rise-over-run value for the relationship in the graph.

Thus, the rise-over-run value for the relationship represented in the graph is 30.
