Answer:
A closed circle would appear on the number line and the arrow should be pointing towards right. The possible solutions could be basically anything greater than or equal to -2, it could be -2, -1, 0, 1, 2, 3, 4 and so on.
Step-by-step explanation:
There are a few things to consider:
1. The inequality symbol:
⇒ [tex]\leq or \geq[/tex] always represented by a closed circle on the number line (this also means that the function x ≥ −2 would contain values greater than -2 but it WOULD also include -2 as an answer, but anything less than -2 would not be included).
⇒ < or > always represented by an open circle on the number line (This also means that the function would contain all numbers greater than -2 but NOT -2 or anything greater).
2. Where the Inequality sign opens:
⇒ If the inequality sign opens towards the variable (a letter) it means that all the values will be greater than the value given in the function. (For example x > 2, since the inequality sign is opening towards the x it means that all values in the solution set would be greater than two and thus the arrow would face the right side. The possible solution set could be 3, 4, 5 and so on)
⇒ If the inequality sign opens towards the number value given, it means that all the values will be less than the value given in the function. (For example, x < 2, in this case the inequality faces towards the number value given so the values for the answer set will have every value less than 2, the solution set would contain values like 1, 0, -1, and so on).

Answer:
x = 19x = 34x = 39Step-by-step explanation:
1. A right angle has a measure of 90°. The whole is the sum of the parts.
(2x +3)° +49° = 90°
2x +52 = 90 . . . . . . . . divide by °, collect terms
2x = 38 . . . . . . . . . . . . subtract 52
x = 19 . . . . . . . . divide by 2
__
2. A linear pair measures 180°. The whole is the sum of the parts.
(x -5)° +151° = 180°
x +146 = 180 . . . . . . . divide by °, collect terms
x = 34 . . . . . . . . .subtract 146
__
3. We presume this pair of angles is supposed to be supplementary. That is, their sum is 180°.
64° +(3x -1)° = 180°
3x +63 = 180 . . . . . . . divide by °, collect terms
3x = 117 . . . . . . . . subtract 63
x = 39 . . . . . divide by 3

840/2=420
30. Consider the diagram below. Solve for x.
Answer:
x = 111°
Step-by-step explanation:
The 2 vertical lines are parallel.
So the sum of the 2 interior angles are equal to 180°.
x + 69° = 180°
x = 111°

Answer:
C = -13.78
Step-by-step explanation:
Answer:
c = -13.78
Step-by-step explanation:
21.2x + c =5.3(4x - 2.6)
Use distributive property: a*(b + c) = (a*b) + (a * c)
21.2x + c = 5.3*4x - 5.3*2.6
21.2x + c = 21.2x - 13.78
Now to find the value of c, isolate 'c'. So, subtract 21.2x form both sides
21.2x + c - 21.2x = 21.2x - 13.78 - 21.2x
c = -13.78

Jordyn got 15 out of 20 questions correct on her quiz. What percent did she get correct? (Provide the % symbol in your answer)
Answer:
75%
Step-by-step explanation:
Hello!
I'd love to help.
An easy method to finding a percentage is converting it into a decimal.
First though, we must simplify 15/20, which would be 3/4, (please let me know if you need the process of simplification)
Then we find the decimal.
We divide the numerator by the denominator.
3 ÷ 4 = .75
Which means that our final answer is:
75%

d) 52.6
e) 5.26
f) 0.526
Step-by-step explanation:
Answer:
a=5260, b=52600, c=526000, d=52.6, e=5.26, f=0.526
Step-by-step explanation:
When you are multiplying by multiply of 10 (a-c) you add the number of zeros there are on the multiply of ten so for c 526000(times 1000). If it is less than 1 you just multiply the numbers and then push the decimal point however far it is in the problem so for problem f 526*1=526 and the decimal the 3 number to the right so you push it back 3 and get 0.325.
