<u>Inequalities</u>
To solve the inequality:
We need to perform the required operations on both sides of the inequality to have the variable w isolated.
First, we subtract 9:
Subtracting 6w:
Operating:
-7w>-1
Now we divide by -7 but recall that when dividing by a negative number, we must flip the inequality sign:
Operating:
Solution:
Answer:
(-6+y)-3y=28
-2y-6=28
-2y=34
y=-17
Then,
x=-6-17
x=-23

Answer:
What's '2−7x'
Step-by-step explanation:
So you have x, then you square it to get x^2, then you minus 2x, then +3
The inverse is going backwards so you -3 then +2x then square root x
So you get square root x + 2x -3
I'm pretty sure this is right, sorry if I'm wrong.
