Answer:
(x, y) = (2, 1)
Step-by-step explanation:
The x-coefficients are opposites of each other, so the x variable will be eliminated if the two equations are added.
(x +3y) +(-x -y) = (5) +(-3)
2y = 2
y = 1
Substituting into the first equation gives ...
x +3(1) = 5
x = 2 . . . . . . . subtract 3
The solution is (x, y) = (2, 1).
Answer:ill help all triangles should equal to 180 hope it did help you
Step-by-step explanation:
The resultant graph is shown in the attached image.
Explanation:Before we begin, remember that when we multiply by a negative sign, we flip the sign of the inequality
The given inequality is:
-y ≤ 3x - 5
We will multiply both sides by -1 to get a positive y vale. This will give us:
y ≥ -3x + 5
Now, to graph the inequality, we will first draw the line y = -3x + 5 and then shade the region having y values greater than the line.
To know the region, you will simply use trial and error method for random points on the two sides of the line.
The final solution would be as shown in that attachment.
Hope this helps :)
