Answer:
0 ≤ x ≤ 8
Step-by-step explanation:
Given
4 ≤ x + 4 ≤ 12 ( subtract 4 from each of the 3 intervals
0 ≤ x ≤ 8
2(9 + 4x) + 6(2 - x) = 7x. i need help asap pleasee
Step-by-step explanation:
18 + 8x + 12 - 6x = 7x
30 + 2x = 7x
30 = 7x - 2x
30 = 5x
Divide both sides by 5
X = 6
Isaac walks for 7 miles to the store from his house. He buys candy and a sandwich to eat for lunch. He then
walks home when he is done eating. Explain, in your own words, how we can figure out how many miles he walked in total?
Answer:
14 miles
Step-by-step explanation:
Isaac is walking 14 miles because if it is seven miles to the store, he has to walk seven miles back. Seven plus seven is fourteen.

The graph shows the relationship between time and the number of soda bottles a machine can make. Use the points (4,112) and (6,168) to find the number of soda bottles the machine can make each minute.
Using y to represent number of bottles filled in x minutes, y = 250x.
This is rather basic, and I urge you to think about it so that it's very clear to you, and you will be able to do similar problems on your own in the future.
The graph will be a straight line passing through the origin (0,0).

1) The standard form of a linear equation is written as .
ax + by=c
a. Write the equation in slope-intercept form( y= mx + b)
b. Write the slope, y-intercept form of (a).
PLS HELP
Answer:
[tex]\displaystyle y=-\frac{a}{b}x+\frac{c}{b}[/tex]
Step-by-step explanation:
The equation of the line, expressed in slope-intercept form is:
[tex]y=mx+y_o[/tex]
Where m the slope and yo the y-intercept.
Since we are given the line in standard form:
ax+by=c
To find the slope-intercept form, we just solve it for y:
[tex]\boxed{\displaystyle y=-\frac{a}{b}x+\frac{c}{b}}[/tex]
Comparing the last equation with the slope-intercept form:
[tex]\displaystyle m=-\frac{a}{b}[/tex]
[tex]\displaystyle y_o=\frac{c}{b}[/tex]
Answer:
ax + by = c
-ax -ax
by=ax+c
then dived both sides by b to get y by itself
y= a/bx +c

For the equation y+1= -3(x-5) the line contains the point (5,-1) and has a slope of?
Answer:
I think its (0,-3)
Step-by-step explanation:
I took the coordinates you gave me and placed they X axis where the X was and put the Y axis where the Y was and got that answer
The required slope of the line is -3 for the equation y + 1 = -3(x-5) the line contains the point (5,-1).
What is the slope of the line?The equation for a line in slope-intercept form is given by y = mx + b, where m is the slope of the line and b is the y-intercept (the point where the line crosses the y-axis).
To put the equation y + 1 = -3(x - 5) into slope-intercept form, we need to solve for y. We can do this by subtracting 1 from both sides of the equation, which gives us y = -3(x - 5) - 1. We can then distribute the -3 on the right side of the equation to get y = -3x + 15 - 1. Finally, we can simplify this to get y = -3x + 14.
In this equation, m = -3 and b = 14. We can verify that this is the correct equation by substituting the coordinates of the point (5,-1) into the equation and solving to see if the equation is true. When we substitute the values into the equation, we get -1 = -3(5) + 14, which is true.
Therefore, the slope of the line is m = -3.

Alexander Litvinenko was poisoned with 10 micrograms of the radioactive substance Polonium-210. Since radioactive decay follows a compounded continuously model, we can determine the amount of substance left in Alexander Litvinenko's body at any given time. If Polonium-210 has a decay rate of .502%, then determine the amount of Polonium-210 left in his body after 72 days. Provide 3 decimal places and a label in your answer.
Answer:
The amount of Polonium-210 left in his body after 72 days is 6.937 μg.
Step-by-step explanation:
The decay rate of Polonium-210 is the following:
[tex] N(t) = N_{0}e^{-\lambda t} [/tex] (1)
Where:
N(t) is the quantity of Po-210 at time t =?
N₀ is the initial quantity of Po-210 = 10 μg
λ is the decay constant
t is the time = 72 d
The decay rate is 0.502%, hence the quantity that still remains in Alexander is 99.498%.
First, we need to find the decay constant:
[tex] \lambda = \frac{ln(2)}{t_{1/2}} [/tex] (2)
Where t(1/2) is the half-life of Po-210 = 138.376 days
By entering equation (2) into (1) we have:
[tex] N(t) = N_{0}e^{-\frac{ln(2)}{t_{1/2}}*t}} = 10* \frac{99.498}{100}*e^{-\frac{ln(2)}{138.376}*72} = 6.937 \mu g [/tex]
Therefore, the amount of Polonium-210 left in his body after 72 days is 6.937 μg.

During a musical an orchestra is playing. As the music plays, the volume changes in the beginning of the piece can be modeled by the equation s = 10│x - 4│+ 50 where s represents the sound level in decibels and x represents the number of measures of music played. Explain in words each step to find the following question:
At what number(s) measures played would the sound level be at 80 decibles?
( I need the answers, plus the steps please and thank youuu :)
Answer:
Kindly check explanation
Step-by-step explanation:
Given the model:
s = 10│x - 4│+ 50
s represents the sound level in decibels and x represents the number of measures of music played
To find x at s = 80
The equation becomes /
80 = 10│x - 4│+ 50
Subtract 50 from both sides of the equation
80 - 50 = 10 |x - 4| + 50 - 50
30 = 10 | x - 4 |
Divide both sides by 10
30/10 = 10|x - 4| / 10
3 = |x - 4|
|x - 4| is an absolute value expression
±3 = |x - 4|
x = 3 + 4 = 7
x = - 3 + 4 = 1

Answer:
10. X = 2.75
11. X = 1.61
Hey there, I have the steps listed below but what is the problem asking, I cannot solve it unless it explains the problem. Thank you!
Step-by-step explanation:
10. 5x + 10 + 11x + 2 = 56
16x + 12 = 56
16/16x = 44/16
X = 2.75
11. -1 + 8x + 18x + 5 = 46
26x + 4 = 46
26/26x = 42/26
X = 1.61

Problem 10
Answers:x = 11angle UTS = 65angle AUT = 123-----------------------
Explanation:
The remote interior angles UTS and TSU add to the exterior angle AUT. This is because of the remote interior angle theorem. The interior angles you add cannot be adjacent to the exterior angle.
(angle UTS) + (angle TSU) = angle AUT
(5x+10) + (58) = 11x+2
5x+10+58 = 11x+2
5x+68 = 11x+2
68-2 = 11x-5x
66 = 6x
6x = 66
x = 66/6
x = 11
Use this x value to find that...
angle UTS = 5x+10 = 5*11+10 = 65
angle AUT = 11x+2 = 11*11+2 = 123
==========================================
Problem 11
Answers:x = 4angle CDB = 31angle WBC = 77-----------------------
Explanation:
We'll use the same theorem as before
(angle BCD) + (angle CDB) = angle WBC
(46) + (-1+8x) = 18x+5
46-1+8x = 18x+5
8x+45 = 18x+5
45-5 = 18x-8
40 = 10x
10x = 40
x = 40/10
x = 4
angle CDB = -1+8x = -1+8*4 = 31
angle WBC = 18x+5 = 18*4+5 = 77
Write each set in the indicated form. If you need to use "" to indicate a pattern, make sure to list at least four elements of the set. As you answer below, remember that the natural numbers are just the counting numbers. This means that is not a natural number, and negative numbers are not natural numbers either.
Complete question is;
Write each set in the indicated form.
If you need to use "..." to indicate a pattern, make sure to list at least four elements of the set.
As you answer below, remember that the natural numbers are just the counting numbers. This means that is not a natural number, and negative numbers are not natural numbers either.
(a) Roster form: {6,8,10,12,...}
Descriptive form:
(b) Descriptive form: The set of natural numbers greater than or equal to 3 and less than or equal to 6.
Roster form:
Answer:
A) Descriptive form: A set of even natural numbers that are greater than or equal to 6.
B) Roster form: {3, 4, 5, 6}
Step-by-step explanation:
A) We are given that the roster form is;
{6,8,10,12,...}
Now, the descriptive form is just a statement that describes the given roster form.
Now, we can see they are all even natural numbers and the least is 6 while after 12,we can see that the set continues.
Thus;
Descriptive form: A set of even natural numbers that are greater than or equal to 6.
B) We are given that the descriptive form is the set of natural numbers greater than or equal to 3 and less than or equal to 6.
This means the least number in the set is 3 while the highest number is 6.
Thus,the roster form is;
Roster form: {3, 4, 5, 6}
The sum of two numbers is 48. If the second number is 6 less than the first, what
is the value of EACH of the numbers?
Answer:
let the first no. be x
then the second no. = x - 6
their sum is 48
therefore,
[tex] = > x + (x - 6) = 48 \\ = > 2x = 48 + 6 \\ = > 2x = 54 \\ = > x = \frac{54}{2} \\ = > x = 27[/tex]
The value of first no. = x = 27
The value of second no. = x - 6 = 27 - 6
= 21
