Answer:
x−5=11−3x
Group all the constants at one side
That's
x + 3x =11 + 5
4x = 16
Divide both sides by 4
4x/4 = 16/4
x = 4
Hope this helps you
Answer:
x=4
Step-by-step explanation:
x−5=11−3x
take care of all the variables
you want to put the variables on one side and the numbers on the other
x−5=11−3x
+3x +3x
4x-5=11
+5 +5
4x=16
÷4 ÷4
x=4

which graph represents the hyperbola x2/32-y2/82=1?
Answer:
Step-by-step explanation:
You have the following hyperbola:
[tex]\frac{x^2}{32}-\frac{y^2}{82}=1[/tex] (1)
The general for of a hyperbola:
[tex]\frac{x^2}{a^2}-\frac{y^2}{b^2}=1[/tex]
To construct the graph you take into account the rectangle formed by the lines x=±a and y=±b, and the asymptotes of the diagonals of the rectangles.
Furthermore, you take into account the foci of the hyperbola, which are
(0,±a).
Then, you have the lines
x = ± √32
y = ± √82
And the foci:
(0, ± √32)
The graph is shown in the attached image.

Answer:
14, 16
Step-by-step explanation:
The prime factorization of 224 is 2⁵ × 7. To make it a perfect square, we need the bases to have an even exponent, therefore we divide it by 2 × 7 = 14 to get 16.

factorize xsquare-25
Answer:
The answer is (x + 5)(x - 5).
Step-by-step explanation:
Assuming that 25 is a perfect square so you can apply :
[tex](a + b)(a - b) = {a}^{2} - {b}^{2} [/tex]
Test :
[tex](x+5)(x-5) = {x}^{2} - 5x + 5x - 25 [/tex]
[tex](x+5)(x-5) = {x}^{2} - 25 [/tex]
Answer:
[tex]\boxed{(x-5)(x+5)}[/tex]
Step-by-step explanation:
x² - 25
Factor out square.
(x)² - (5)²
Apply difference of two squares formula.
a² - b² = (a-b)(a+b)
a = x
b = 5
x² - 25 = (x-5)(x+5)

In triangle △JKL, ∠JKL is right angle, and KM is an altitude. JL=25 and JM=5, find KM.
HELP ME PLEASE!!!!!!
Answer:
KM = 15
Step-by-step explanation:
From the diagram, ΔJKL and ΔJKM are similar to each other because they share the same angle J and they are both right angle triangle. Therefore they are similar by AA property.
Since JL=25 and JM=5, JM = JL + JM= 25 + 5 = 30
Since ΔJKL and ΔJKM are similar to each other, therefore:
[tex]\frac{JK}{JL}=\frac{JM}{JK}\\ Substituting:\\\frac{JK}{30}=\frac{5}{JK}\\JK^2=150\\JK=\sqrt{150}\\ \\From\ hypotenuse:\\JK^2=JM^2+KM^2\\Substituting:\\(\sqrt{150} )^2=5^2+KM^2\\150=25+KM^2\\KM^2=150-25=125\\KM=\sqrt{125}\\ KM=15[/tex]

Answer:
9f^2 - 12f + 4.
Step-by-step explanation:
(3f - 2)^2

Answer:
G.
Step-by-step explanation:
Since the y-int is (0, 4), you know you have to have an equation that has a +4 in it. When you calculate for the slope, you should get 4/3, and so the only equation that has those 2 is G.

Pleasseeee help me It's for a test Mars is extremely far from the Earth. Scientists estimate that it could take astronoauts 245 days to travel from Earth to Mars. This is more than half of a year! Suppose astronauts travel to Mars when the distance between Earth and Mars is 108 million miles. If the trip takes 245 days, on average, how many miles would be traveled each day? In your calculator, write the large number as a multiple of a power of 10 to compute the answer. Round to the nearest mile.
Answer:
440,816 miles per day

Determine whether the samples are independent or dependent. upper a data set includes the morning and evening temperature for the lasta data set includes the morning and evening temperature for the last 90 days.90 days.
Answer:
Dependent sample
Step-by-step explanation:
The sample: a data set includes the morning and evening temperature for the last 90 days.
The samples are dependent in that they are paired measurements on just one set of item which is the temperature.
These measurements are related in such a way that the each observation in one sample can be paired with an observation in the other sample.

Hey there! :)
Answer:
[tex]\frac{121}{9}[/tex]
Step-by-step explanation:
We can solve this by first converting -3 2/3 to an improper fraction:
[tex]-3\frac{2}{3} = \frac{-11}{3}[/tex]
Square the fraction:
[tex](\frac{-11}{3})^{2} = (\frac{-11}{3}) * (\frac{-11}{3}) = \frac{121}{9}[/tex]
What is the value of x in the equation 3x – 1/9 = 18, when y = 27?
Answer:
Here you go mate!
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
3x - 1/9y = 18
Put y as 27 and evaluate.
3x - 27/9 = 18
3x - 3 = 18
Add 3 on both sides.
3x = 21
Divide 3 on both sides.
x = 7
PLEASE HELP, AND PLAESE EXPLAIN!!!
Answer:
D. 22.5 sq. un.
Step-by-step explanation:
W divides BU so that there is a ratio of 1;2 meaning that there are 3 parts.
That means that 3 parts is BUV; we know that one of those parts is 4.5 sq. un. so 4.5*3=13.5 sq. un. - Also 4.5*2=9 to get WUV
V is the midpoint of the line BS so that means that BUV and UVS are equal
we know that BUV is 13.5 so we multiply that by 2 to get the whole triangle
=27
The last step is to get rid of BVW which we know is 4.5
27-4.5=22.5

Which property can be used to solve the equation? StartFraction d Over 10 EndFraction = 12 addition property of equality subtraction property of equality multiplication property of equality division property of equality
Answer:
multiplication property of equalityStep-by-step explanation:
Given the equation d/10 = 12. To get the value of d, the follwoing steps can be used to solve for the value of d;
Multiply both sides by 10
d/10 * 10 = 12*10
d = 120
It can be seen from the calculation above that multiplication operation was used to get the solution to the equation. It can therefore be concluded that the multiplication property of equality was used to solve the equation.

Q3. Samir spins a fair coin and records the results. In the first four spins ‘Heads' comes up each time. Samir says, ‘A head is more likely than a tail'. Is he correct? YES/ NO Give a reason for your answer.
Answer:
The conclusion drawn by Samir is Not correct.
Step-by-step explanation:
The spinning of a fair coin is a Bernoulli experiment.
There are only two outcomes: Heads (H) or Tails (T).
Theoretically, each of the two outcomes has an equal probability of occurrence i.e. P (H) = P (T) = 0.50.
Now, suppose an experiment is conducted to test this theory.
The law of large numbers, in probability concept, states that as the number of times an experiment is conducted, say n, in increased, the average value of the experiment approaches the expected value.
To determine whether ‘A head is more likely than a tail', the experiment of spinning the coin must be repeated more than n = 4 times.
In statistics, n = 30 is considered as a large enough sample.
So, the conclusion drawn by Samir is Not correct.
In a regression analysis with multiple independent variables, multicollinearity can be caused by: A strong nonlinear relationship between the dependent variable and one or more independent variables A strong heteroskedastic relationship between the dependent variable and one or more independent variable A strong linear relationship between two or more independent variables None of the above
Answer:
A strong linear relationship between two or more independent variables
Step-by-step explanation:
Multicolinearity underestimates the statistical significance of the independent variables. It exists when an independent variable is highly correlated with one or many other independent variables giving rise to a large standard error.

Find The surface area of the pyramid
Answer:
85 ft^2
Step-by-step explanation:
Let us calculate the area of the triangles and the base.
For the triangles, we can use the area formula and get 5 • 3 which is 15. Since there are 4, we multiply it by 4 and get 60.
For the base, we have 5 • 5, which is 25. Adding it together, we get 85.
If you are stuck on how to find surface area, all you have to do is find the area of each side and add.
I hoped this helped!
Heather draws a polygon with x number of sides. The sum of the interior angles of her polygon is 60 times the number of sides. How many sides does Heathers polygon have?
Answer: hexacontagon
has 60 sides and interior angles is 10440 degrees.
Step-by-step explanation:
I kinda think its wrong but hope this helps, if its wrong, im sorry
Answer:
Heather's polygon has 3 sides.
Step-by-step explanation:
S = 60x Try plugging in number for x that will work
I found that when x = 3, the equation was true
S = 60x Substitute
S = 60(3) Multiply
S = 180 If the sum of the interior angles is 180, the only shape that can be made is a triangle, which has 3 sides.
