One carpet cleaning cost are shown in the table. The relationship is linear. Find and interpret the rate of change and the initial value for this situation.
Answers
The first costs $125. Supposing we subtract $50 from that, we get $75. So, it sounds like it costs $75 just to get the carpet cleaners to your house.
The rule would then be $75 + $50x, where x : {1, 2, 3, 4, .... }
Let's check this result. Suppose x = 1. Will the charge be $125, as show in the table? $75 + $50(1) = $125. Correct.
Suppose x = 4. Will the charge be $275 as shown in the table?
$75 + $50(4) = $275. YES

After m months, the height of a plant is 10+3m millimeters. How tall is the plant after 8 months? 3 years?
Answers
After 8 months, the plant is 34 millimeters tall, and after 3 years (36 months), it's 118 millimeters tall.
To find the height of the plant after 8 months and 3 years, let's first understand the pattern. The height is given by the equation ( 10 + 3m ), where ( m ) represents the number of months.
Height after 8 months:
Substituting ( m = 8 ) into the equation:
[tex]\( \text{Height} = 10 + 3(8) \)[/tex]
[tex]\( \text{Height} = 10 + 24 \)[/tex]
[tex]\( \text{Height} = 34 \)[/tex] millimeters.
Height after 3 years (36 months):
Substituting ( m = 36 ) into the equation:
[tex]\( \text{Height} = 10 + 3(36) \)[/tex]
[tex]\( \text{Height} = 10 + 108 \)[/tex]
[tex]\( \text{Height} = 118 \)[/tex] millimeters.
So, after 8 months, the plant is 34 millimeters tall, and after 3 years (36 months), it's 118 millimeters tall.

Mr. Venn knows that 60% of his students will score no more than 5 points above or below the class average,75% on the test.
Write an inequality that represents the test scores of 60% of his students?
Answers
Answer:
[tex]70\leq x\leq 80[/tex]
Step-by-step explanation:
Let x represent the test scores of 60% of his students.
We have been given that Mr. Venn knows that 60% of his students will score no more than 5 points above or below the class average,75% on the test.
We will use tolerance formula to solve our given problem.
[tex]|\text{Actual}-\text{Ideal}|\leq\text{Tolerance}[/tex]
[tex]|x-75|\leq5[/tex]
Using rule [tex]|u|\leq a[/tex], then [tex]-a\leq u\leq a[/tex], we will get:
[tex]-5\leq x-75\leq5[/tex]
[tex]-5+75\leq x-75+75\leq5+75[/tex]
[tex]70\leq x\leq 80[/tex]
Therefore, the inequality [tex]70\leq x\leq 80[/tex] represents the test scores of 60% of Mr. Venn's students.

Question 2: The answer is: " -12.8 ".
_______________________________________________________
Question 3: The answer is: " 12.3 " .
_______________________________________________________
Explanation:
_______________________________________________________
Question 1:
_______________________________________________________
(-4/3) − (-3/2) = [tex] \frac{-4}{ 3} [/tex] + [tex] \frac{3}{2}[/tex] ;
→ The least common multiple (LCM) of the numbers "2" and "3" (which are the numbers in the denominators) is: "6" ; so we can convert each fraction value to the equivalent fraction with a denominator of "6" ;
→ [tex] \frac{-4}{3} [/tex] = [tex] \frac{?}{6} [/tex] ;
→ What value is the "?" ? ; → Look at the denominators.
→ (3 * ? = 6); → (6÷3 = 2).
→So; [tex] \frac{-4}{3} [/tex] = [tex] \frac{-4*2}{3*2} [/tex] ;
= [tex] \frac{-8}{ 6} [/tex] ;
_______________________________________________________
→ Now; → [tex] \frac{3}{2} [/tex] = [tex] \frac{?}{6} [/tex] ;
→ What value is the "?" ? ; → Look at the denominators.
→ (2 * ? = 6); → (6÷2 = 3).
→So; [tex] \frac{3}{2} [/tex] = [tex] \frac{3*3}{ 2*3} [/tex] ;
= [tex] \frac{9}{6} [/tex] ;
_______________________________________________________
Now, we can rewrite the problem:
________________________________
→ [tex] \frac{-8}{ 6} [/tex] + [tex] \frac{9}{ 6} [/tex] ;
= [tex] \frac{-8+9}{6}[/tex] ;
= [tex]\frac{1}{6} [/tex] .
_______________________________________________________
Question 2:
_______________________________________________________
" -3.9 − 8.9 " = - (3.9 + 8.9) = - 12.8 .

Question 3:
_______________________________________________________
" 2.9 − (-9.4) " = 2.9 + 9.4 = 12.3 .

How many 4-digit numbers can you write if you cannot use any other digits except 0, 1, and 2?
Answers
There are 54 possible 4-digit numbers that can be created using only the digits 0, 1, and 2, considering that the first digit cannot be 0 and each position has a limited selection of digits.
Explanation:To determine the number of 4-digit numbers that can be written using only the digits 0, 1, and 2, we must take into account that a 4-digit number cannot start with 0, which leaves us two choices for the first digit (either 1 or 2). For the subsequent three digits, we have three choices each (0, 1, or 2). Therefore, the total number of 4-digit combinations is obtained by multiplying the number of choices for each digit's position.
The explanation you provided is correct, and the calculation is accurate. There are indeed 54 possible 4-digit numbers that can be created using only the digits 0, 1, and 2, considering the given conditions.
To summarize:
- The first digit has 2 possible choices (1 or 2).
- Each of the next three digits has 3 choices (0, 1, or 2).
So, the total number of 4-digit combinations is obtained by multiplying the number of choices for each digit's position:
\[2 \times 3 \times 3 \times 3 = 54.\]
Therefore, there are 54 possible 4-digit numbers that can be created following the given conditions.
The first digit has 2 possible choices, and each of the other three positions has 3 choices, which gives us a total of:
2 × 3 × 3 × 3 = 54 possible 4-digit numbers using the digits 0, 1, and 2.

1.1 Factoring: x3-216
Theory:
A difference of two perfect cubes, a3 - b3 can be factored into
(a-b) • (a2 +ab +b2)
Proof : (a-b)•(a2+ab+b2) =
a3+a2b+ab2-ba2-b2a-b3 =
a3+(a2b-ba2)+(ab2-b2a)-b3 =
a3+0+0+b3 =
a3+b3
Check: 216 is the cube of 6
Check: x3 is the cube of x1
The solution to the equation x³ + 216 = 0 is x = -6, by subtracting 216 from both sides and taking the cube root.
Explanation:To solve the equation x³ + 216 = 0, you must first isolate the variable on one side of the equation. To do this, we can subtract 216 from both sides, giving us the equation x³ = -216.
Next, to solve for x, we need to take the cube root of -216. The cube root of -216 is -6, so x = -6 is the root of the equation.
In conclusion, the solution to the equation x³ + 216 = 0 is x = -6.

Step-by-step explanation:
Great question, it is always good to ask away and get rid of any doubts that you may be having.
Based on this question we can see that the movie theater has 1 action movie for every 2 other type of movies. We can add these two numbers together and divide by 24 to find out how many action movies are playing compared to the other types of movies.
[tex]1 + 2 = 3[/tex]
[tex]24 / 3 = 8[/tex]
8 action movies : 16 other type of movies
As we can see from the adjusted ratio above, there are 8 action films being shown
