You need to solve this "system of linear equations." In other words, find a point (x,y) that satisfies both 4x-3y=17 and 2x-5y=-11.
Try solution by elimination. Multiply the 2nd equation by -2 to obtain -4x+5y=22. Add this result to the 1st equation. I'd suggest you write this out to see what is happening.
4x-3y=17
-4x+10y=22
----------------
7y=39. Solving for y, we get y=39/7 (a rather awkward fraction).
Now find x. To do this, substitute 39/7 for y in either of the given equations. Solve the resulting equation for x.
Write your solution in the form (x, y): ( ? , 39/7).
Answer:
6 vertices and 5 faces
Step-by-step explanation:
The faces are correct as there are 3 rectangles and 2 triangles.
So a total of 5 faces
There are 6 corners/vertices so the answer is 6 vertices
Answer:
Try 150
Step-by-step explanation:
I'm not sure but it might work.
