Answer:
B Is correct
Step-by-step explanation:
Solve the solution set and divide to get the points and whether to fill them in or not.
-5 filled in, and 5 open circle
The graph of the solution set can be seen in option B.
What is a solution set?
The solution set is the set representing all solutions for an equation. It is also the roots that obey a quadratic equation or an inequality.
From the given equation, we have:
[tex]\mathbf{\dfrac{x^2+9x+20}{x^2-x-20}\ge 0}[/tex]
Let's factor out the quadratic equation, we have:
[tex]\mathbf{\dfrac{(x+4)(x+5)}{(x+4)(x-5)}\ge 0}[/tex]
By identifying the intervals;
x ≤ -5 or x > 5
The representation of these intervals on a graduated scale on a number line can be seen in the image attached below.
Therefore, we can conclude that the correct graph that show the solution set to the given equation can be seen in Option B.

Answer:
Step-by-step explanation:
d is on a line with s so they are supplementary d+80 = 180 so d has to be 100
s and h are equal, therefore vertical angle x is also 80
Then 80 + 60 + y = 180 since they are on a straight line so y=40

What is the area of 19 centimeters?
Answers
Let's break this up:
Radius: 19
Diameter: 38
Circumference: 119.4
So...
The area of a circle with radius 19 is 1134
A = πr2 = π(d
2
)2 A = C2
4π
π = 3.1415
A = area
C = circumference or perimeter
r = radius, d = diameter
SOLUTION STEPS:
Area of a circle in terms of radius:
Area = π·r2 = 3.14·192 = 1134 square cm(*)
Area of a circle in terms of diameter:
Area = π·(d
2
)2 = 3.14·(38
2
)2 = 3.14·(19)2 = 1134 square cm(*)
Area of a circle in terms of circumference:
Area = C2
4π
= 119.42
4π
= 14256.36
(4·3.14)
= 14256.36
12.56
= 1134 square cm(*)
(*) 1134.1149479459 cm, exactly or limited to the precision of this calculator (13 decimal places).
Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.
Result in other units of area:
A circle of radius = 19 or diameter = 38 or circumference = 119.4 cm has an area of:
1.134 × 10-7 square kilometers (km²)
0.1134 square meters (m²)
1134 square centimeters (cm²)
1.134 × 105 square millimeters (mm²)
4.3784 × 10-8 square miles (mi²)
0.135625 square yards (yd²)

Which of the following is a solution of the system 2x + y = 9 and 3x + 5y = 19.
Answers
2x+y=9
3x+5y=19
I will do this problem in 2 ways. I.)Substitution II.)Elimination
Solution I.) Substitution
We can subtract 2x from both sides in the first equation.
y=9-2x
Now we can substitute the y in the second equation with 9-2x
3x+5(9-2x)=19
-7x+45=19
-7x=-26
x=26/7
y=9-2(26/7)=11/7
Solution II.)Elimination
We can multiply both side of first equation by 5 to get a 5y in both equations.
10x+5y=45
Now because both are positive 5y we just need to do simple subtraction of the 2 equation, each side respectively.
(10x+5y)-(3x+5y)=45-19
7x=26
x=26/7
2*26/7+y=9
y=11/7
Ultimately you get the same answer, both are viable methods, some problems are faster with one method but I recommend mastering both since they are very useful.

A. 52
B. 50
C.90
D. 92
Answers
The value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.
What is quadrilateral?
It is defined as the four-sided polygon in geometry having four edges and four corners and two pairs of congruent sides.
We have:
In the diagram below, OP is circumscribed about quadrilateral ABCD.
In a quadrilateral, the sum of the opposite angles is equal to 180 degree
x + 20 + 110 = 180
x + 130 = 180
x = 50
Thus, the value of x is 50 because, in a quadrilateral, the sum of the opposite angles is equal to 180 degrees. option (B) is correct.
