Please solve the equation below.
2x+4=3(x-4)
Answer:
x=16Step-by-step explanation:
[tex]\sf 2x+4=3(x-4)[/tex]
[tex]\sf 2x+4=3x-12[/tex]
[tex]\sf 2x+4-4=3x-12-4[/tex]
[tex]\sf 2x=3x-16[/tex]
[tex]\sf 2x-3x=3x-16-3x[/tex]
[tex]\sf -x=-16[/tex]
[tex]\sf \cfrac{-x}{-1}=\cfrac{-16}{-1}[/tex]
[tex]\sf x=16[/tex]
solve the equation below :-
2x+4=3(x-4)
Answer:-x = 16
Explanation:-=> 2x+4 = 3(x-4)
=> 2x+4 = 3x-12
=> 2x+4 - 4 = 3x-12 - 4 (Subtract 4 on both the sides)
=> 2x = 3x-16
=> 2x-3x = -16
=> -x = -16
=> -x/-1 = -16/-1
=> x = 16

Mikayla designed a survey to determine the number of people expected at opening night of a community theater. The community has about 5,000 members. She selected a sample of the first 25 parents dropping off actors during theater rehearsal. Which best explains Mikayla’s sample? random and biased random and unbiased nonrandom and biased nonrandom and unbiased.
The sample is based on the first 25 parents dropping off actors during theater rehearsal hence the sampling method is non random and biased.
A non random sample refers to a sampling method that is not based on chance alone. A biased sampling is one in which some members of the population are more likely to be selected thereby excluding the others.
Since the sample is based on the first 25 parents dropping off actors during theater rehearsal, the sampling method is non random and biased.

3. Gracie graphed the line 3x – 4y = -16. Which
ordered pair is in the solution set of 3x – 4y = -16?
19
A.(-2,3)
C. (2,7)
B.(-8,0)
D. (0,-1)
We want to see which ordered pair is a solution for the given line. We will see that none of the points is a solution for the given equation.
So, if you have a graph this is rater easy.
In a point (x, y) the first value represents the horizontal displacement and the second represents the vertical displacement.
So, to see if the points are solutions of the line, you just need to see if the point lies on the graphed line.
Below you can see the graph, there you also can see all the given points.
There you can see that none of the given points lie on the line, so none of these is in the solution set of the line (you can also check this by evaluating the equation in the given points).

x > -19
x < -1
x < -19
x > -1
Answer:
x > - 1
Step-by-step explanation:
- 10 < x - 9 ( add 9 to both sides )
- 1 < x , therefore
x > - 1
Answer:
x > -1
Step-by-step explanation:
why:
-10 < x-9 for exemple 2< 3
x-9 > -10 3 > 2
just add 9 to both sides
x-9 +9 > -10 +9
x > -1

The sum of two integers is 2. Their difference is 10. What are the two integers?
Answer:
6 and -4
Step-by-step explanation:
a + b = 2
a - b = 10
Solve:
from the first eq.
a = 2 - b
replacing this value in the second eq.
(2-b) - b = 10
2 - 2b = 10
-2b = 10 - 2
-2b = 8
b = 8/-2
b = -4
from the second eq.
a - b = 10
a - (-4) = 10
a + 4 = 10
a = 10 - 4
a = 6
Check:
from the first eq.
6 + (-4) = 2
6 - 4 = 2

Find the domain of the expression.
the square root of x+5
See attachment for answer and math work.
Answer:
Step-by-step explanation:
"Domain" means what numbers are allowed to be x (or on a graph, for what x's does the graph exist)
Since inside a square root you have to have a positive number (actually, just not a negative number). So all the positive numbers work (any positive+5 is a positive number) BUT ALSO x can be 0, BUT ALSO, x can be as small as -5 and still the value inside the square root will not be negative
SO THIS MEANS all the x's we're allowed to use (that's the DOMAIN) are everything from -5 and bigger. In math we write that as x>= -5
There are two other main ways to write it: [-5, infinity symbol) OR {x|x>=-5} these all mean the same thing.
