Hello!
We 1st off, know that number of pencils = x
and that the number of pens = y
So now the Solving!:
3x + y = 10
x ≤ y
Draw the line 3x + y = 10 .[it passes by (0,10) and (-10/3,0)
Draw the line y=x [it passes by (0,0), (1,1), (2,2) etc]
Then the solution is the points with integer x and y, that belong to the segment of the line 3x +y = 10 between the x-axis and the line y=x. Those points are (1,7) , (2,4), (3, 1).
I Hope my answer has come to your Help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead! :)
Answer:
I think its Z (-5, 7)
Step-by-step explanation:
Here :)
DCB form a right angle which is 90 degrees.
The two inside angles need to equal 90
ACB = 90-65 = 25
Answer: 25
Answer:
Line that passes through the points (-6,5) and (-2,7) is,
y=x/2+8, slope is 1/2
line that passes through the points (4,2) and (6,6) is,
y=2x-6, slope is 2
so, there is no relationship between those two lines,
intersection point is (28/3,38/3)
