Answer:
64
Step-by-step explanation:
4^3 is the same as 4x4x4
4x4 = 16
16x4=64
so 4^3 is 64
The set of all numbers less than or equal to -8 or greater than or equal to 2 is -8 ≥ x ≥ 2. The set is {x∈R|-8 ≥ x ≥ 2}
<h3>The set of numbers</h3>
From the question, we are to write the set of numbers l<u>ess than or equal</u> to -8 or<u> greater than or equal</u> to 2
Let x represent the set of the numbers
If a number is less than or equal to -8
Then,
-8 is greater than or equal to the number
That is,
-8 ≥ x
If a number is greater than or equal to 2
Then,
x ≥ 2
Thus, the set of all the numbers is
-8 ≥ x ≥ 2
Hence, the set of all numbers less than or equal to -8 or greater than or equal to 2 is -8 ≥ x ≥ 2. The set is {x∈R|-8 ≥ x ≥ 2}

Answer and Step-by-step explanation:
The expression is equal to 90.
This is because the lines that cut the right angle are cutting it in half, so those base angles are 45, leaving the center angle to be 90 (90 + 45 + 45 = 180).
90 = 19x + 4.5
85.5 = 19x
x = 4.5
<u>The value of x that makes the parallelogram a square is 4.5.</u>

From any proportion, we get another proportion by inverting the extremes (or the means):
= k
so we have:
2x=3k
2x+y=2k therefore:
3k+y=2k
y= - k
x=
= -
The corect answer is A. -3/2
or:
From any proportion, we get another proportion by inverting the extremes and the means:
We use a property of proportions:
where a, d are extremes and b,c are means and the product of the extremes equals the product of the means (a*d=b*c),
so we have
or
(you can check this also by "the product of the extremes equals the product of the means")
3y = - 2x
