hi someone pls help me!
Step-by-step explanation:
let y = f(x)
82 = x^2 + 1
81 = x^2
x = ±9
y = (3)^2 + 1
y = 10
26 = x^2 + 1
25 = x^2
x = ±5

Hola me podrian ayudar con este interrogatorio por favor.. Armando recibio 135.000 para pagar los servicios,El telefono cuesta 47.550,el acueducto 69.700 y la energia 24.750 ¿es suficiente el dinero que recibio Armando? ¿por que?
Answer:
El dinero que recibió Armando no es suficiente porque recibió $135.000 y tiene que pagar $142.000.
Step-by-step explanation:
Primero, tienes que sumar los gastos para encontrar la cantidad que Armando tiene que pagar:
47.550+69.700+24.750=$142.000
De acuerdo a esto, el total a pagar es $142.000 y Armando recibió $135.000 por lo cual el dinero que recibió no es suficiente porque el total que tiene que pagar es más alto.
The time it takes to clean up after an anniversary party varies inversely as the number of people cleaning. If 3 people work together to clean, it will take them 90 minutes. How long will it take if the number of people cleaning is increased to 5?
Answer:
54minutes
Step-by-step explanation:
Let the time taken to clean up be t
Let the number of people cleaning be n
If the time it takes to clean up after an anniversary party varies inversely as the number of people cleaning then;
t = k/n
k is the constant of proportionality
If 3 people work together to clean, and took them 90 minutes, this means
at t = 90, n=3
Substitute
90 = k/3
k = 3×90
k = 270
To et the time it will take 5people to clean, the will say;
t =k/n
t =270/5
t = 54 minutes
Hence it will take 5 people 54minues to clean
Answer: 54 minutes

If f(x)=7(x−1)+8 , what is the value of f(3) ?
Answer:
22
Step-by-step explanation:
f(3) = 7(3-1) + 8
f(3) = 7(2) +8
f(3) = 14 + 8
f(3) = 22
Answer:
f(3) = 22
Step-by-step explanation:
To evaluate f(3), substitute x = 3 into f(x), that is
f(3) = 7(3 - 1) + 8
= 7(2) + 8
= 14 + 8
= 22

Determine the equation of the line satisfying the following condition.
Containing the point (-1,-5) and parallel to 3x+2y=9
Answer: y=-3/2x-13/2
Step-by-step explanation:
To find a line parallel to the given line, we know that the two equations must have the same slope. We first want to find the slope of the given equation.
3x+2y=9 [subtract both sides by 3x]
2y=-3x+9 [divide both sides by 2]
y=-3/2x+9/2
Now, we know the slope if -3/2. All we have to do is plug in the given point to find the y-intercept.
-5=-3/2(-1)+b [multiply]
-5=3/2+b [subtract both sides by 3/2]
b=-13/2
Now, we know the equation is y=-3/2x-13/2.

Thanks
Answer:
2x+3y=13 ------(1)
4x-y=-2 -----(2)
Multiply (1) by 2,
=> 4x + 6y = 26. ---(3)
Subtract (2) from (3),
4x - 4x + 6y + y= 26 + 2
7y = 28
y = 4
x = (13-3(4))/2
x = 1/2.

The random variable X takes on the values of 2, 5, n, and 15. The probability distribution of X is shown in the following table
The question is missing some parts. Here is the complete question.
The random variable X takes on the values of 2, 5, n and 15. The probability distribution of X is shown in the table below.
The expected value of X is 9.1. What is the value of n?
a) 8
b) 8.52
c) 10
d) 12
e) 14.4
Answer: d) 12
Step-by-step explanation: In a probability distribution, Expected Value is the average (or mean) value a distribution can assume.
The Expected Value, E(X), can be determine by:
[tex]E(X)=\Sigma xP(x)[/tex]
in which
x is how many times an event happens
P(x) is the probability of an event happening
The table below n is x and expected value is 9.1, then:
[tex]9.1=2*0.1+5*0.4+0.2n+15*0.3[/tex]
[tex]9.1=0.2n+6.7[/tex]
[tex]0.2n=2.4[/tex]
n = 12
Value of n in this probability distribution is 12.
The value of n in the discrete probability distribution given is 12.
The the sum of [P(X) × X] in a discrete probability distribution is the expected value
From the discrete probability table given :
P(X) × X can be expressed as :
E(X), expected value = 9.1(0.1 × 2) + (5 × 0.4) + (15×0.3) + 0.2n = 9.1
0.2 + 2.0 + 4.5 + 0.2n = 9.1
6.7 + 0.2n = 9.1
0.2n = 9.1 - 6.7
0.2n = 2.4
n = 2.4 / 0.2
n = 12
Therefore, the value of n in the table is 12

Sam cleaned 1/3 of his house in 50 minutes. How many hours will it take him to clean his entire house?
please give me the correct answer and full explanation
This is equivalent to equivalent to 2 hours, 30 minutes.
======================================================
Work Shown:
1/3 of the house = 50 minutes
3*(1/3 of the house) = 3*(50 minutes)
3/3 of the house = 150 minutes
1 house = 150 minutes
-----------
Sam will need 150 minutes to clean the whole house
Divide this over 60 to convert to hours
150 minutes = (150/60) hours
150 minutes = 2.5 hours which is the final answer
-----------
Or you could say the following
150 minutes = 120 min + 30 min
150 minutes = (120/60) hr + 30 min
150 minutes = 2 hr + 30 min
This shows that 2.5 hours is equivalent to 2 hours, 30 minutes.

Answer:
r=√(A/π)
r=2.8
Step-by-step explanation:
We want to get (r) alone on one side
A=πr^2
divide each side by π
A/π=r^2
square root each side
√(A/π)=r
r=√(A/π) is the answer to your first question.
now we are given A
r=√((25)/3.14)
put the left side into a calculator
r=2.8216632
round to nearest tenth of a centimeter
r=2.8

Flora reflects the point (5, -10) across the y-axis. What are the coordinates of the reflected point explain how u know
Answer:
(-5, -10)
Step-by-step explanation:
(5, -10) is in quadrant 4.
When it reflects on the y-axis, it lands in quadrant 3.
Quadrant 3 is all negative coordinates.
The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
Reflected along the y-axis from IV Quadrant to II Quadrant
The coordinate will change using the form as,
(x, -y) → (-x, -y)
The coordinate of the reflected point is (-5, -10)
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
Coordinates = (5, -10)
This is in IV Quadrant
If it is reflected across the y-axis.
(5, -10) will be in the III Quadrant.
Now,
The y-coordinate will remain the same but the x-coordinate will change its sign.
The coordinate will change using the form as,
(x, -y) → (-x, -y)
(5, -10) → (-5, -10)
Thus,
The coordinates of the reflected point is (-5, -10)
