Answer:
8 - 2x <4 gives us x>2
|x-8| >22 gives us (-inf, -14) and (30,inf)
|x+5| < 4 gives us (-9,-1)
Step-by-step explanation:
Inequalities differs from equalities in that they return a range of values for x and not a single value (case of equalities)
The first one
8 - 2x <4 if you subtract every side 8, you will get -2x<-4
Next divide every side with -2, since its a negative number you have to change the orientation of the inequaiity, thus we have x>4/2, x>2
The second
|x-8| >22, it has to be treated as this. -22>x-2>22 which can be treated as two single inequalities, -22>x-8, and the other, x-8>22. The fist gives you x<-14, and the other x>30, two non intercepting ranges, so your range will be (-inf, -14) and (30, inf)
The third
|x+5| < 4 if you apply the same steps from above, you will have the following -4<x+5<4 This results in two intercepting ranges, giving you the range (-9,-1)

Answer:
Hi there!
The answer to this question is c=23, b and d=157
this is because c is the vertical angle of a meaning the values are equal
and b is the supplementary angle to a: all you do is subtract 23 from 180 to get 157.
b is vertical to d, so d is also 157
Answer:20
Step-by-step explanation:
because you are finding out the base so width times length
Divide, 10/8, you get your answer. Then add that answer with 4.32 . After that, Sudtract, 291.15x-1.94x, Then you put that to the right.
