Consider the compound inequality x < 4 and x>a. If a=4 and the compounding word were "or" instead of "and",what would the
FinnZ [79.3K]

Answer:

We have:

x < 4 AND x > a.

if a = 4 and we use an "or" instead of the "and" we have:

x < 4 or x > 4.

This is:

"x is larger than 4 or smaller than 4."

Then the solution of this is all the real numbers except the value x = 4.

The set of solutions can be written as:

{xI x ∈ R  \ [4]}

Where this reads:

"x belongs to the set of the reals minus the number 4".

Or we also could write it as:

x ∈ (-∞, 4) ∪ (4, ∞)

Where we have two open ends in the "4" side, so the value x = 4 does not belong to that set.

Andrej [43]
Answer: 48

first you do 2x3 then divided by 2 to get one of the small triangles which is 6/3= 2 then double that to get the other small triangle so you have 2+2=4
then you find the area of the rectangle which you do 8+3 to get the whole of the length so it’s then 11x4= 44
then add the 4 from the two triangles and you get the area as 48

Find the measure of the missing angles.
Verdich [7]

Answer:

x = 57                y = 137

Step-by-step explanation:

x + 43 + 90 = 180

x + 43 + 90 - 90 = 180 - 90

x + 43 = 90

x + 43 - 43 = 90 - 43

x = 57

43 + y = 180

43 + y - 43 = 180 - 43

y = 137
