Given the expression y + 8
The unknown variable is y while the known value is 8. You can see that the mathematical sign between them is a summation (plus) sign. The expression can therefore be translated as the sum of a number and eight
what’s the slope?? Please help
Answer:
Slope of the line represented by the table is 2.5.
Step-by-step explanation:
For a linear function,
Slope of the line passing through two points \((x_1,y_1)\) and \((x_2,y_2)\) is given by,
Slope = \(\frac{y_2-y_1}{x_2-x_1}\)
Therefore, slope of the line passing through (0, 12) and (-2, 7) will be,
Slope = \(\frac{12-7}{0-(-2)}\)
= \(\frac{5}{2}\)
= 2.5
Therefore, slope of the line represented by the table is 2.5.

Pass journal entries using the perpetual system of inventory-
Purchased 1000 units of shoes from Indiana International at $300 each on account
Sold 200 units to Ceridian Corporation at $500 each on account
Sold 500 units to Semed Inc. at 550 each on cash
Paid cash in full to Indiana International
Purchased 800 units of shoes from CITS at $450 each on cash
Sold 100 units to Deeman Corp at $600 each on cash
The passage of journal entries to record the transactions, using the perpetual system of inventory with the First-in, First-out (FIFO) method, is as follows:

11. Students in a math class are divided into 8 equal groups with a least
3 students in each group for a project.
Write an inequality to describe the possibile numbers of students in each
group
Use the Multiplication Property of Incqualay to write an inequality to
describe the possible numbers of students in the class.
Answer:
Inequality for each group is \(x \ge 3\) where x is the number of students in a group.
The inequality for the entire class is \(8x \ge 24\)
There are at least 24 students in the class.
==============================================================
Explanation:
x = number of students per group
We have at least 3 students per group, which means x = 3 is the lowest we can go. This forms the inequality \(x \ge 3\)
Use the multiplication property of inequality to multiply both sides by 8 because we have 8 equal groups
\(x \ge 3\\\\8*x \ge 8*3\\\\8x \ge 24\\\\\)
There are at least 24 students in the class. In other words, there are 24 or more students in the class.

Craig wants to use an elevator to carry identical packages having the same weight. Each package weighs 4 pounds and Craig weighs 90 pounds. If the elevator can carry a maximum of 330 pounds at a time, which inequality shows the maximum number of packages, n, that Craig can carry with himself in the elevator if he is the only passenger?
Answer:
90+4n less than or equal to 330
Step-by-step explanation:
since craig weighs 90 pounds. he will be a constant weight
Since each package weighs 4 pounds, the variable will be 4n
The elevator can hold a maximum of 330 pounds so that is what the inequality should have on the other side
the final equation will be:
90+4n less than or equal to 330

x=?
yeshsfhdthgff
Answer:
x = -3
Step-by-step explanation:
-8(x + -7) = 80
Multiplication signs rule:
+ * - = -
- * - = +
Then:
-8(x - 7) = 80
-8*x -8*-7 = 80
-8x + 56 = 80
-8x = 80 - 56
-8x = 24
x = 24/-8
x = -3

Which is the following in an irrational number?
A. -8.264264264...
B. -5/9
C. 17.47
D. 4.28192489...
*
Answer:
D
Step-by-step explanation:
Irrational numbers are those which cannot be expressed by the ratio of two integers.
A is rational because it is a recurring decimal. Recurring decimals can be represented by the ratio of two integers (this one can be represented by the fraction -2752/333, which is a ratio of two integers).
B is a fraction with two integers, therefore it is rational. -5/9 is a ratio of two integers.
C can be represented by 1747/100.
D is an infinite decimal but isn't recurring like A, meaning it cannot be represented by the ratio of two integers, and is therefore it is irrational, unless you are shown further digits of the decimal which prove it to be recurring, which is not the case here.

Step-by-step explanation:
using the definition
n\(C_{r}\) = \(\frac{n!}{r!(n-r)!}\)
where n! = n(n - 1)(n - 2) ... × 3 × 2 × 1
then
12\(C_{4}\)

The original plan for assigning telephone numbers that you investigated in
Applications Task 4 was implemented in
1947. At that time, the supply of numbers was expected to last for 300 years. However, by the 1970s the numbers were already starting to run out. So, the numbering plan
had to be modified. In this task, you will count the number of different phone numbers that were available in 2012.
a. For three-digit area codes, the first digit cannot be a 0 or a 1. Assuming no additional restrictions, how many three-digit area codes are possible under
this plan?
b. Certain area codes are classified as "Easily Recognizable Codes" (BRCs).
ERCs designate special services, like 888 for toll-free calls. The requirement for an ERC is that the second and third digit of the area code must be the same. The first digit again cannot be a 0 or a 1. How many ERCs are there?
c. Consider the seven digits after the area code. As with the area code, the first digit of the three-digit local prefix cannot be a 0 or a 1. The remaining six digits for the local number have no restrictions. How many of these seven-digit phone numbers are possible?
d. Assuming only the 0 and 1 restrictions in Parts a and c, how many ten-digit phone numbers are possible?
a. Assuming no additional restrictions, there are 800 possible three-digit area codes.
b. Considering ERCs, there are 80 ERCs.
c. For the seven digits after the area code, there are \(8 \times 10^6 = 8,000,000\) possible seven-digit phone numbers.
d. Assuming only the 0 and 1 restrictions from parts a and c, the number of possible ten-digit phone numbers is 800 \(\times\) 8,000,000 = 6,400,000,000.
a. For three-digit area codes, the first digit cannot be 0 or 1.
Assuming no additional restrictions, there are 8 possibilities for the first digit (2-9) and 10 possibilities for each of the remaining two digits (0-9). Therefore, the total number of three-digit area codes possible under this plan is \(8 \times 10 \times 10 = 800.\)
b. For an ERC (Easily Recognizable Code), the second and third digits of the area code must be the same, and the first digit cannot be 0 or 1. There are 8 possibilities for the first digit (2-9) and 10 possibilities for the third digit (0-9).
Since the second digit must be the same as the third digit, there is only 1 possibility.
Therefore, the total number of ERCs is \(8 \times 1 \times 10 = 80.\)
c. For the seven digits after the area code, the first digit of the three-digit local prefix cannot be 0 or 1.
There are 8 possibilities for the first digit (2-9) and 10 possibilities for each of the remaining six digits (0-9).
Therefore, the total number of seven-digit phone numbers possible is 8 * \(10\times 10 \times 10 \times 10 \times 10 \times 10 = 8,000,000.\)
d. Assuming only the 0 and 1 restrictions from parts a and c, the number of possible ten-digit phone numbers can be calculated by multiplying the number of possibilities for each digit position.
For the area code (part a), there are 800 possibilities.
For the seven digits after the area code (part c), there are 8,000,000 possibilities.
Therefore, the total number of ten-digit phone numbers possible is 800 * 8,000,000 = 6,400,000,000.
