3)
=w^12z^18
answer
C. w^12z^18
4)
= 4x^6
answer
B. 4x^6
It should look like this (x,y). so the x variable goes first and y goes second
No 7x3/5 is 4.2 and 4x1/5 is 0.8
Isolate the y for both questions. Note that what you do to one side, you do to the other. Do the opposite of PEMDAS.
First question: x - 5y ≥ 3
First, subtract x from both sides
x (-x) - 5y ≥ 3 (-x)
-5y ≥ -x + 3
Divide -5 from both sides. Note that when you divide by a negative number, you flip the equation.
(-5y)/-5 ≥ (-x + 3)/-5
y ≤ (-x + 3)/-5
y ≤ x/5 - 0.6
------------------------------------------------------------------------------------------------
Do the same for the second one. Subtract x from both sides
x + y < 0
x (-x) + y < 0 (-x)
y < - x
