Answer:
As j decreases, the expression increases.
Step-by-step explanation:
As j decreases, the expression will increase. This is because once it becomes a lower number, it will subtract less from 150, and it will soon eventually add towards with 150, if j is negative.
Hope this helps!
Answer:
All have exactly one solution
Step-by-step explanation:
a) -13x + 12 = 13x - 13
+13x +13x
-------------------------------
12 = 26x - 13
+13 +13
-------------------
25 = 26x
----- ------
26 26
25/26 = x
b) 12x + 12 = 13x - 12
-12x -12x
-----------------------
12 = x - 12
+12 +12
-----------------
24 = x
c) 12x + 12 = 13x + 12
-12x -12x
-----------------------------
12 = x + 12
0 = x
d) -13x + 12 = 13x + 13
+13x +13x
-----------------------------
12 = 26x + 13
-13 -13
-----------------------
-1 = 26x
--- -----
26 26
-1/26 = x
<span>y^8 = 4
y^7 = 3/x
y(y^7) = 3/x(y)
y^8 = 3y/x
3y/x = 4
3y = 4x
y = 4x/3
