Answer:
1. C.
2. B.
3. Add 6.1 to both sides
Step-by-step explanation:
1. Your equation here is "w + 2 < -1"
You must get w by itself, so to do that, subtract 2 from both sides.
w + 2 < -1
w < -3
Notice that the symbol is "w is less than -3" not "w is less than or equal to -3," so our plot must have a closed circle (or no open circle).
The larger the number behind the negative sign, the smaller it is.
ex: -3 is smaller than -1
So, the answer is C.
2. Here, you have the inequality -15 > q - 5
To find out which number set best fits the inequality, substitute the numbers in for the q value.
[I'll skip to answer B.]
B.'s number set is {-11, -12, -14}
So, plug in each value for q
For -11:
-15 > (-11) - 5
-15 > -16
This works.
(As I mentioned earlier, the larger the number in front of the negative, the smaller it is.)
For -12:
-15 > (-12) - 5
-15 > -17
This works as well
For -14:
-15 > (-14) - 5
-15 > -19
This works too
Thus, the answer is B.
3. And finally, you have the equation p - 6.1 = 10
To solve for p, make sure its alone on one side of the equation.
To do this, add 6.1 to both sides.
This is the first (and pretty much only) step to solve this equation
I hope this helps!!! :)
