Answer:
4th option because the two negatives will become positive and the 3rd will make it negative again
-4x - 8 > -20
Add 8 to both sides
- 4x > -12
Divide both sides by -4
**When you divide by a negative you must change the direction of the inequality sign**
x < 3
Letter C
You basically have to find the slope, to find the average rate of change, because finding the slope and finding the average rate of change is basically the same thing.
Here's the formula :
So here, all you'd have to do is simply pick two points, and insert them into this formula. Say you take the points (-2, -2) and (0,-3). You would start from the y-intercept of the second point, and insert them all into the formula.
which would turn into
. And so since you want a good, stable number, and not just a fraction, you would divide -1 and 2, and the average rate of change would be
-0.50.
AVERAGE RATE OF CHANGE :
-0.50
Step-by-step explanation:
let x be the number
5(x - (12 - 4x))= -36
Answer:
-
Step-by-step explanation:
-x= -1x. (The 1 is invisible)
Now lets do the 3*-1= -3
You still have both of the x's.
All you do is add them. 1+1=2
So, your exponent is going to be 2 with x attached
***When you are multiplying and you have the same exponent, add them. Pretend that you see the exponent 1 by the x () now since you have 2 () which equals ()
Looks Like:
3x* -x
=3x* -(1)x
=
Hope this helped :)
