Answer:
2,100 people
Step-by-step explanation:
~Divide to find the number of people in fifths
3,500 / 5 = 700
~Multiply to find 2/5 of the total people
700 * 2 = 1,400
~Subtract to find the number of people against building the school.
3,500 - 1,400 = 2,100

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.

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

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.
Hope this helps :)
One number exceeds another by 12 and their sum is 44 find the two numbers you
Answer:
Step-by-step explanation:
x - first
x + 12 - second
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
x + (x + 12) = 44
2x=44-12
x=16
Therefore first number is 16
second number is 16+12=28

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.
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

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

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)
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

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

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.
