Find the value of x.
95
38°
X
Answer:
47
Step-by-step explanation:
x is one of the three angles of a triangle. The other two are given as 95 and 38.
Together all three have to make 180 degrees.
x + 95 + 38 = 180
x + 133 = 180
x = 180 - 133
x = 47
Answer:
47
Step-by-step explanation:
as we know that sum of a triangle is always=180°
so x+38°+95°=180
so x+133=180
and x=180-133
so x= 47
Among 2000 respondents, 113 said that they've experienced depression in the past 12 months. What percentage of respondents said they've experienced depression in the past 12 months?
Type your answer as a percent without the percent sign. Do not round.
Answer:
5.65%
Step-by-step explanation:
Find the percent of respondents that said they had experienced depression by dividing 113 by 2000:
113/2000
= 0.0565
Multiply this by 100:
0.0565(100)
= 5.65
So, 5.65% of the respondents said they had experienced depression in the past 12 months.
Does anyone know how to finish this equation?

The points represented by the (x,y) coordinate pairs in the table below all lie on line k. What is the slope of line k?
Answer:
the slope is -2/1
You can find it by using the equation [tex]\frac{y_{1}- y_{2} }{x_{1}- x_{2} }[/tex]
so 3-1/1-2= 2/-1, which is also written as -2/1
Do the following graphs represent a mathematical function? If not, explain why.
Answer:
Yes for bothStep-by-step explanation:
In such cases use the vertical line test. If the graph is intersected at more than one point, it is not a function.
Both the given graphs represent a function as both pass the vertical line test.
Answer:
Yes
Step-by-step explanation:
Whenever you are given a problem that's asking to see if a graph is a function or not, always use the vetical line test to determine that. In short, you draw a line accross each y axis point and if the line only goes accross one point throughout the graph then it's a function. Following the test we will see that both graphs are indeed functions.
Best of Luck!

brainiest to whoever right
Answer:
since M lies between point A and B , we came to know that,
M(4,6) =(x,y)
A(-2,-1)=(x1 ,y1)
B( _, _ )=(x2,y2)
Now using mid point formula,
x=x1×x2÷2 y=y1+y2÷2
so, point B is (10,13)
a rectangle is 9 inches wide and 2 inches long. What is the area of this rectangle
Answer:
18 inches²
Step-by-step explanation:
The formula for the area of a rectangle is: [tex]A=lw[/tex]
l = lengthw = widthSubstitute the given values for the variables.
[tex]A=(9)(2)=18[/tex]
Therefore, the area of the rectangle is 18 inches².
Answer: Area = 18 inches²
Concept:
Here, we need to know how to find the area of a rectangle.
Area (rectangle) = l × w
l = length
w = width
If you are still confused, please refer to the attachment below for a graphical explanation.
Solve:
Given information
l = 2 inches
w = 9 inches
Given equation
Area = l × w
Substitute values into the equation
Area = 2 × 9

Finds real root off(x)=x3 +x2 +x+7=0
9514 1404 393
Answer:
x ≈ −2.10487278573
Step-by-step explanation:
I find a graphing calculator to be a very useful tool for the purpose. It shows the only real root is irrational and gives an approximation as x=-2.105.
The calculator also provides the means to perform Newton's method iteration easily to refine the value of the root to full calculator precision.
__
The Newton's method iterator for finding the next iteration of the root (x') is ...
x' = x - f(x)/f'(x)
Starting with the approximation shown on the graph, it only takes two iterations to get the root to the full precision of the calculator.

State the domain of each function.
1. [tex]g(a)=\sqrt{1+a^{2}}[/tex]
2. [tex]f(x)=\frac{2}{x} + \frac{4}{x+1}[/tex]
Please show your work, as the steps are the only reason I'm asking.
Answer:
[tex] \rm \displaystyle g(a) = \sqrt{1 + {a}^{2} } \xrightarrow{ \rm Domain}a \in \mathbb{R}[/tex]
[tex] \rm\displaystyle f(x)=\frac{2}{x} + \frac{4}{x+1} \xrightarrow{ \rm Domain}x \in \mathbb{R} / \{0, - 1 \}[/tex]
Step-by-step explanation:
Question-1:we want to figure out the domain of the following function:
[tex] \displaystyle g(a) = \sqrt{1 + {a}^{2} } [/tex]
remember that, the domain of an even root function are all values of x for which the redicand is positive or 0 that is being said the domain of the function g(a) belong to [tex]\mathbb{R}[/tex] . another way to think about it, the domain of square root function f(x) belong to x≥0. In this case we have square variable in the redical so when we input a negative number, it yields a positive number with that said the domain of the function g(a) belong to all the real numbers.Thus,
[tex] \rm \displaystyle g(a) = \sqrt{1 + {a}^{2} } \xrightarrow{ \rm Domain}a \in \mathbb{R}[/tex]
Question-2:we'd like to find the domain of the following function:
[tex] \displaystyle f(x)=\frac{2}{x} + \frac{4}{x+1}[/tex]
in order to do so we need to simplify it further,so simplify addition in order to do so the first step is to figure out the LCM of the denominator i.e x(x+1) ⇒ x²+x, secondly divide the denominator of every fraction by the LCM and multiply the result by the numerator of very fraction ,then finally add them therefore,
[tex] \displaystyle f(x)=\frac{2x + 2+4x}{ {x}^{2} + x } \\ \displaystyle \boxed{\frac{6x + 2}{ {x}^{2} + x }} [/tex]
we know that the domain of a rational function are all the values of x for which the denominator is different than 0.
the denominator of the function would be 0 when x=0 and -1 thus,
[tex] \rm\displaystyle f(x)=\frac{2}{x} + \frac{4}{x+1} \xrightarrow{ \rm Domain}x \in \mathbb{R} / \{0, - 1 \}[/tex]
and we're done!

What are two ways you could represent the expression 3-4n
There are not just "the two ways" to represent this expression. There are two ways, surely, but they are not the only ways as implied.
You could expose 4 and get something like [tex]4(\frac{3}{4}-n)[/tex] or expose 3 and get something like [tex]3(1-\frac{4}{3}n)[/tex].
But you could also say something like [tex]3-(1+3)n=3-n-3n=-3(n-1)-n[/tex]... in fact there are a lot of ways to write any expression.

6 large boxes an 2 small boxes weighs 92 kilograms 3 large boxes and 5 small boxes weigh 71 kilograms how much does each type of box weigh
Answer:
Large Box weighs
13.25 kg and Small box weighs 6.25 kg
Step-by-step explanation:
Let the large box be L and small box be S
According to question,
6L + 2S = 92 kg .... (i)
and 3L + 5S = 71 kg ....(ii)
Subtracting we get,
3L - 3S = 21 kg
or L - S = 7 kg
or L = 7 + S kg ... (iii)
Now, putting the value of L in eqn (i) we get
6 (7+S) + 2S = 92 kg
or 42 + 6S + 2S = 92
or 8S = 50
or S = 50/8
or S = 6.25 Kg
Then, 6L + (2×6.25) = 92 kg
or, 6L = 92 - 12.5
or, L = 79.5/6
or, L = 13.25 kg
solve -5x+y=1 and 9x-2y=4 using multiplication and then elimination.
Answer:
x = - 6, y = - 29
Step-by-step explanation:
Elimination:
2*(-5x + y = 1) = -10x + 2y = 2
9x - 2y = 4 = + (9x - 2y = 4) =
-x = 6
x = -6
9(-6)-2y=4
-54-2y=4
-2y=58
y=-29

b. Only the mean and mode are equal.
c. Only the median and mode are equal.
d. The mean, median, and mode are all equal.
Answer:
D.
Step-by-step explanation:
Mean : 7 + 5 + 6 + 4 + 7 + 8 + 12 = 12 + 10 + 7 + 20 = 30 + 19 = 49. 49/7= 7
Mode : 7.

Answer:
m=79
t=54
Step-by-step explanation:
yes these are the answers
Answer:
angle t = 54 degrees
angle m=79(alternate angles)
Step-by-step explanation:
angle p=126 degrees
angle z=79 degrees
angle p + angle t=180(allied angles)
126 + t =180
t =180-126
t = 54 degrees
u=79(vertically opposite angles)
therefore;
angle m=79(alternate angles)

The perimeter of the triangle below is 4x + 3y. Find the measure of the missing side.
Answer:
let side be t
t + x + y +x + y = 4x + 3y
t + 2x + 2y = 4x + 3y
t = 2x +y
so missing side length is 2x + y

x + (x + 12) = 44
2x=44-12
x=16
first number is 16
second number is 16+12=28
two numbers are 16 and 28
16 and 28 are the required two numbers when one number exceeds another by 12 and their sum is 44
One number exceeds another by 12 and their sum is 44
We need to find the two numbers
What is equation?Two expressions with equal sign is called equation.
Let x be the first number
x + 12 be the second number
