Answer:
Key features: the functions can not be parallels, this means that their respective slopes can not be equal or multiple to the other
Step-by-step explanation:
Take for instance 2 linear functions, and
If they intersect in some point in the space, say that is
Then (x1,y1)=(x3,y3), (x2.y2)= (x3,y3)
So, we can compare the two functions and get the following result;
It tells us that if M=m, we get an error, meaning that the functions are in fact parallels and there is no way that they meet in some point.
hope this helps!
Answer:
The range is all real numbers greater than or equal to 2
Step-by-step explanation:
we know that
Observing the graph
The solution for the variable y is
therefore
The range is the interval -----> [2,∞)
All real numbers greater than or equal to 2
Answer:
x = 46
Step-by-step explanation:
Here, we want to get the value of the angle marked x
From the diagram given , the two angles that are other than x can be gotten from the value of their supplements
Angles on a straight line are supplementary as they add up to 180
Thus, mathematically;
(180-130) + (180-96) + x = 180
50 + 84 + x = 180
x = 180-50-84 = 46
Answer: 6
Step-by-step explanation:
The total amount needed by Kallen for the gift and the wrapping paper will be:
= $43.87 + $2.94
= $46.81
Since he earns $8.25 for each lawn he mows, the number of lawns they he will need to complete to buy the gift and wrapping will be:
= $46.81 / $8.25
= 5.67
= 6 lawns approximately
He'll need to mow 6 lawns
