It appears that all choices have the 1st part the same, so we are looking at domains. I recommend drawing the functions without the domain limitations. We know that the linear function is closed so it's inequality is either [tex]\geq[/tex] or [tex]\leq[/tex]. So eliminate B and D. Since the quadratic function continues to the left the inequality sign should be <. So the answer is C

2(6x+9−3x)=5x+21 PLEASE HELP !!
Answer:
x=3
Step-by-step explanation:
Simplifying
2(6x + 9 + -3x) = 5x + 21
Reorder the terms:
2(9 + 6x + -3x) = 5x + 21
Combine like terms: 6x + -3x = 3x
2(9 + 3x) = 5x + 21
(9 * 2 + 3x * 2) = 5x + 21
(18 + 6x) = 5x + 21
Reorder the terms:
18 + 6x = 21 + 5x
Solving
18 + 6x = 21 + 5x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-5x' to each side of the equation.
18 + 6x + -5x = 21 + 5x + -5x
Combine like terms: 6x + -5x = 1x
18 + 1x = 21 + 5x + -5x
Combine like terms: 5x + -5x = 0
18 + 1x = 21 + 0
18 + 1x = 21
Add '-18' to each side of the equation.
18 + -18 + 1x = 21 + -18
Combine like terms: 18 + -18 = 0
0 + 1x = 21 + -18
1x = 21 + -18
Combine like terms: 21 + -18 = 3
1x = 3
Divide each side by '1'.
x = 3
Answer:
x=3
Step-by-step explanation:
(12x+18-6x)=5x+21
6x+18=5x+21
x+18=21
x=3
Find the sum of the measures of the interior angles of a hexagon. A. 900. B.360. C. 720. D.1080

What is the sum of the interior angles of a polygon?The sum of the interior angles of a polygon is given by the formula
Sum of Interior angles of a polygon with n sides is
nθ = 180 ( n - 2 )
where n is the number of sides
θ = angle in degrees
Given data ,
Let the sum of the interior angles of a hexagon be S
Let the polygon be represented as a hexagon
Now , the number of sides of a hexagon is n = 6
So , sum of Interior angles of a polygon with n sides is
nθ = 180 ( n - 2 )
On simplifying , we get
nθ = S = 180 ( 6 - 2 )
S = 180 x 4
S = 720°
Therefore , the value of S is 720°
Hence , the sum of the interior angles of hexagon is 720°

Answer:
584!
Step-by-step explanation:
Let's see. There is a missing side. Let's call that x. However, we know what the other sides are!
This is how we do it.
We know the largest side's length., 172.
Since we know the other sides, we can subtract their length from 172.
172-57-51-31=33
x=33
So now add the sides!

3) The sum and the difference of the LCM and GCD of two numbers are 312 and 264 respectively. Find the numbers if their sum is 168.
Answer:
The numbers are 72 and 96.
Step-by-step explanation:
LCM + GCF = 312
LCM - GCF = 264
2*LCM = 576
LCM = 576/2 = 288
HCF = 312–288 = 24
The product of two numbers = HCF*LCM
Let the numbers be x and (168-x)
x(168-x) = 24*288 = 6912
x^2–168x+6912 = 0
x = [168 +(168^2 -4*6912)^0.5]/2
= [168 +(28224–27648)^0.5]/2
= [168 + 576^0.5]/2
= (168+24}/2
= 192/2
= 96 and the other number is 168–96 = 72.

The height of a parallelogram is three times its base. If the area of the parallelogram is 675 square inches, find its base and height.
Which of these choices are correct?
b = 25 in & h = 75 in
b = 75 in & h = 225 in
b = 45 in & h = 135 in
b = 25 in & h = 12.5 in
Answer:
Step-by-step explanation:
let base be x and height be 3x
we know area of parallelogram is
base*height
ie x*3x=675
3x^2=675
x^2=675/3
x^2=225
x= square root of 225
x=15
therefore base =15
height = 45

Step-by-step explanation:
→You can use the Pythagorean Theorem to solve:
[tex]a^2+b^2=c^2[/tex]
→The "a," and "b," are the legs, and the "c," is the hypotenuse. In this case, we are already given the hypotenuse as 41, and we are trying to find a leg:
[tex]40^2+b^2=41^2[/tex]
[tex]1600+b^2 = 1681[/tex]
→Subtract 1600 from both sides:
[tex]b^2=81[/tex]
→To get "b," by itself, square root both sides, like so:
[tex]\sqrt{b^2} =\sqrt{81}[/tex]
→81 is a perfect square meaning it has two factors that are identical.
[tex]b = 9[/tex]

The coordinates of D'E'F' after reflection are,
D' = (0, - 3)
E' = (1, 0)
F' = (2, - 1)
We have to given that,
Triangle DEF has vertex coordinates D(0, -3), E(-1,0), and F(-2,-1).
Here, Triangle DEF is reflected across the y-axis.
The rule for a reflection over the y -axis is,
(x, y) → (- x, y)
Hence, the coordinates of D'E'F' after reflection is,
D' = (0, - 3)
E' = (- (- 1), 0) = (1, 0)
F' = (- (- 2), (- 1)) = (2, - 1)

Answer:
THE FUNCTION IS ALWAYS INCREASING.
Complete question: The graph of f(x)= power of 3√x + 8 is shown.
Step-by-step explanation:
See attachment for the missing graph.
when x = -16 ; y = -2
when x = -12 ; y = -1.5
when x = -8 ; y = 0
when x = -6 ; y = 1.25
when x = 0 ; y = 2
when x = 6 ; y = 2.5
As the value of x increases, so does the value of y. Thus, the function is always increasing.
