Answer:
x < 1
Step-by-step explanation:
To solve for x, we need to get x by itself
2(5 - x)>8
Distribute the 2
2*5 -2*x >8
10- 2x >8
Subtract 10 from both sides
10-10 -2x >8 -10
-2x > -2
Divide both sides by -2
-2x/-2> -2/-2
Since we divided by a negative number, we must flip the inequality sign
x < 1
Answer:
-6 > - 4
Step-by-step explanation:
If the temperature changed from 17 degree F to -7 , the change was
17+7=24 degrees F
the average change was 24/12=2 , 2 degrees per hour

Answer:

Step-by-step explanation:
Let E be the set of all even positive integers in the universe Z of integers,
i.e
E = {2,4,6,8,10 ....∞}
be the characteristic function of E.
∴

For XE(2)
since x is an element of E (i.e the set of all even numbers)
For XE(-2)
since - 2 is less than 0 , and -2 is not an element of E
For { x ∈ Z: XE(x) = 1}
This can be read as:
x which is and element of Z such that X is also an element of x which is equal to 1.
∴

E = {2,4,6,8,10 ....∞}
