What is the interval notation for the compound inequality? x≤−4 or x≥5
(−∞, −4) or (5, ∞)
(−∞, −4] or [5, ∞)
(−4,5)
[−4,5]
Answer:
(-∞, -4] or [5, ∞)
Step-by-step explanation:
Because the solutions for x can also be equal to -4 and 5, brackets are used.
And because the solutions for x can be any number less than -4 or any number greater than 5, -∞ and ∞ are used respectively.

Any help with this? I need help solving.
Answer:
By AAS or AAA congruence, you can prove it.
I hope it will be useful .
Step-by-step explanation:
angleG=angleE (given)
Corresponding opposite angles formed by the transversal are equal! i.e., angleFDG=angleDFE or vice-versa..
And the side is common! or you can prove it by AAA criteria (two pairs of equal angles made by the transversal)

The diameter of a pearl is about 4 x 10-3cm and the diameter of an atom is about10-11m. How much larger than an atom is a pearl?Show your work.
a)14x 10∧-14times b) 4 x 10 ∧-14timesc) 14x 10∧-11times d) 4 x 10∧6times
Answer:
D. 4 × 10⁶ timesStep-by-step explanation:
The diameter of a pearl is
4 × 10⁻³cm = 4 × 10⁻⁵ mThe diameter of an atom is
10⁻¹¹mHow much larger than an atom is a pearl?
4 × 10⁻⁵ ÷ 10⁻¹¹ = 4 × 10⁻⁵⁺¹¹ = 4 × 10⁶ timesCorrect option is D

Consider the following triangle side lengths and determine if the triangle could exist. Justify your answer. Part A: 21,18,17 Part B: 3,12,8
Answer:
A yes, B no
Step-by-step explanation:
The triangle inequality states that the sum of any 2 sides of the triangle must be greater than the third side.
A Given 21, 18, 17 , then
21 + 18 = 39 > 17
21 + 17 = 38 > 18
18 + 17 = 35 > 21
Thus the triangle could exist
B Given 3, 12, 8 , then
3 + 12 = 9 > 8
3 + 8 = 11 < 12 ← fails the test
Thus the triangle does not exist

Find the y-intercept and x-intercept of the line.
5x-3y=10
Answer:
strategy: put this equation into slope intercept form y = mx + b
then it is easier to find x and y intercepts
Step-by-step explanation:
5x-3y=10
5x-10=3y
5/3x - 10/3 = y
y = 5/3x - 10/3
when x is zero then y is - 10/3, that's the y intercept
when y is zero then x is 2, that's the x intercept
:)
What is the solution to the system below?
y = -3x - 2
6x + 2y = -4
Answer:
Infinitely many solutions
Step-by-step explanation:
Since y=-3x-2, plug it in (2)
6x+2(-3x-2)=-4.
Distribute:
6x-6x-4=-4
-4=-4
Infinetly many solutions.
Hope this helps :)
a mat is 3m long and xm wide what is the area in m²

A classroom is 11 m long, 8 m wide and 5.5 m high Find the sum of the areas of the four walls.
( please show the working out pleaseee)
Answer:
209 m²
Step-by-step explanation:
The class room has a measurement of 11 m long, 8 m wide and 5.5 m high. Hence the walls of the classroom would be 4, with the following measurements.
Wall 1: 11 m by 5.5 m, Wall 2: 8 m by 5.5 m, Wall 3: 11 m by 5.5 m and Wall 4: 8 m by 5.5 m
The area of wall 1 = 11 m * 5.5 m = 60.5 m²
The area of wall 2 = 8 m * 5.5 m = 44 m²
The area of wall 3 = 11 m * 5.5 m = 60.5 m²
The area of wall 4 = 11 m * 5.5 m = 44 m²
The sum of areas of the fall wall = area of wall 1 + area of wall 2 + area of wall 3 + area of wall 4
The sum of areas of the fall wall = 60.5 + 44 + 60.5 + 44 = 209 m²
In the figure, point C is the midpoint of (A/E) Use the figure to answer the questions.
Avery says that AbC /DeC by the ASA congruence postulate. Do you agree or disagree Explain?
Suppose it is also known that point C is also the midpoint of (B/D Which postulate or theorem can be used to prove that aBC/DeC? Justify your answer.
Answer:
Disagree ΔABC ≅ ΔDEC by ASA butt by SAS
Step-by-step explanation:
point C is the midpoint of (A/E), C is also the midpoint of (B/D )
BC = CD and AC = CE
∠BCA = ∠ECD
ΔABC ≅ ΔDEC by SAS not by ASA

f(x) = x2. What is g(x)?
Answer: Choice C. g(x) = (3x)^2
To confirm this, plug in x = 1 and you'll find that:
g(x) = (3x)^2
g(1) = (3*1)^2
g(1) = (3)^2
g(1) = 3*3
g(1) = 9
Showing that (1,9) is on the red g(x) curve.

Express 27 4/3 in simplest radical form
Answer:
3⁴
Step-by-step explanation:
Expressing in the simplest radical form means simplifying a radical so that there are no more square roots, cube roots, fourth roots etc.
It further means removing radicals in the denominator of a fraction.
Given
[tex]27^{4/3}[/tex]
this can be written as
[tex](\sqrt[3]{27} )^{4}[/tex]
This is simplified as;
(3)⁴
