Answer:
-5/2
Step-by-step explanation:
5x +2y = -15
-5x -5x
2y = -5x - 15
y = -5/2x - 7.5
y = mx + b
Slope (m) = -5/2
down 5, right 2
Answer:
36units^2
Step-by-step explanation:
we want to split this triangle into two different triangles, triangle 1 will have verticies (0,0) (3,8) and (3,0). Triangle 2 will have verticies (3,0) (3,8) and (9,0).
next we want to find the area of each of the triangles using the formula 1/2(base)(height)
Once you do this its just a matter of adding the two areas together.
1/2(3)(8)+1/2(6)(8)=12+24=36
X = # 5 inch stones, y = # 10 inch stones
5x + 10y = 145
y = x + 1
5x + 10(x + 1) = 145
5x + 10x + 10 = 145
15x = 135
x = 135/15
x = 9 <=== 9 five inch stones
y = x + 1
y = 9 + 1
y = 10 <=== 10 ten inch stones
