Given:
Line A: 2x + 2y = 8
Line B: x + y = 4
x = 4 - y
2(4-y) + 2y = 8
8 - 2y + 2y = 0
0 = -8
y = 4 - x
2x + 2(4-x) = 8
2x + 8 - 2x = 8
0 = 0
There is no solution.
Answer:
A.1/12
Step-by-step explanation:
Probability of the card being yellow is 1/4
And probability of the card being even is 1/3
And if you are asked to find a yellow even card we multiply those two numbers to get 1/12
To solve this system of equations, since y is already isolated in both equations, you can set the expressions to equal each other to solve for x:
-x + 2 = - 5x - 6
-x + 5x = -6 - 2
4x = -8
x = -2
Now that we have x, we can substitute it into one of the equations to find y:
y = -(-2) + 2
y = 2 + 2
y = 4
The last step is to substitute both values into both equations to see if they are correct:
4 = -(-2) + 2 --> 4 = 2 + 2 <--True
4 = -5(-2) - 6 --> 4 = 10 - 6 <--True
Answer:
x = -2
y = 4
Right 2 up 3 because when the change happens within x the opposite result happens but for vertical it remains the same . So the answer is <span>right 2, up 3</span>
Answer:
Time spend by Adelina at the tutoring session is 30 minutes.
Step-by-step explanation:
Given : In a tutoring session, 
of an hour was spent reviewing math problems and Adelina attended 
of the tutoring session.
We have to find the time Adelina spend at the tutoring session.
We know, 1 hour = 60 minutes.
Total time taken in tutoring session = 
minutes.
also, Adelina attended of the tutoring session that is of 40 minutes.
that is 
minutes.
Thus, time spend by Adelina at the tutoring session is 30 minutes.
