Answer:
x = 12, y = 4
Step-by-step explanation:
x / y = 3
x - y = 8
Or
12 / 4 = 3
12 - 3 = 8
Answer:
slope=2
Step-by-step explanation:
subrtract -4-(-4) the two negatives make it a + so that becomes 8 and thats for the top one the bottom is 6-2 which is 4 then divide 8 by 4 to find the slope which is 2.
Area of a triangle:
A (triangle )= 4 · 6 / 2 = 12 ft²
150 - 12 = 138 ft² ( the maximum area of the rectangle )
L = ?
W = 6 ft
A ( rectangle ) = L · W
L · 6 = 138
L = 138 : 6 = 23 ft.
Answer: the maximum length of the base of the rectangle he can build is 23 ft.
-3b=9a=b-3
-3b=9a
b=-3a
9a=b-3
9a=-3a-3
so,a=-1/4
and b=3/4
solution set is(-1/4,3/4)
