3x +2y= 11 ----1
x -2 = -4y ---- 2
Equation 2 times by 3
3x -6 = -12y
Subracting 2-1
3x-6=-12y
3x-11=-2y
Leaving
5=-10y
y= -1/2
Hence
B. is the solution
PS, If you rate this as "Brainiest" that would be most appreciated
Answer:
= 12 cm^3
Step-by-step explanation:
V = Bh where B is the area of the base and h is the height
For a triangular prism, the base is the triangle
A = 1/2 bh for the triangle
= 1/2 (6*2)
= 6 cm^2
To find the volume for the triangular prism
V = Bh
= 6 * 2
= 12 cm^3
Eq1) 2r+2s=50
eq2) 2r-s=17
solve for s in equation2 (eq2)
-s=17-2r
s=-17+2r
Substitute s into equation1 (eq1)
2r+2(-17+2r)=50
2r-34+4r=50
6r-34=50
6r=50+34
6r=84
r=14
Substitute into either equation and solve for s
2(14)-s=17
28-s=17
-s=17-28
-s=-11
s=11
If they intersect at this point, that means this point is a solution (3,4)
