Answer:
X:1 2 3 4 5 Y:7 11 15 19 23.
Step-by-step explanation:
We just need to put in the values of x into the equation: y = 4x + 3.
x = 1:
y = 4(1) + 3
= 4 + 3
y = 7
x = 2:
y = 4(2) + 3
= 8 + 3
y = 11
x = 3:
y = 4(3) + 3
= 12 + 3
y = 15
x = 4:
y = 4(4) + 3
= 16 + 3
y = 19
x = 5:
y = 4(5) + 3
= 20 + 3
y = 23

Answer:
{13}
Step-by-step explanation:
A ∩ B ∩ C = the set of all elements that are in sets A and B and C
This is indicated in the Venn diagram by the region that is common to all three circles which is the darkly shaded region. There is only one element that is included in this region and that is 13
In roster form we write it as {13}
1. Let A = {2, 5, 6, 7, 9, 10) and B = {2, 5, 6}. Indicate if each statement is
true or false.
(a) 3 EA
(b) BCA
(c) An B = {2,5,6}
(d) AU B = {7,9,10}
Anø=Ø
(e)
(f) n(AUB)
The statements are:
a) False
b) True
c) True
d) False.
e) True.
Which statements are true and which ones are false?Here we have the two sets:
A = {2, 5, 6, 7, 9, 10) and B = {2, 5, 6}
The first statement is:
a) 3 E A
That says "the number 3 belongs to set A". That clearly is false, as the set A does not contain the element 3.
b) B C A
The statement says:
Set B is included in set A. This is true, as all the elements of set B also belong to set A.
c) A n B = {2,5,6}
This is true, that is the intersection between A and B (the intersection between two sets is the set of common elements)
d) AU B = {7,9,10}
This is false, U refers to the union between the two sets, here we should have
A U B = A = {2, 5, 6, 7, 9, 10}
e) Anø=Ø
This is true, trivially all the sets contain the element {∅}

The Option C is correct.
Mark and Gary had a basketball game Saturday.
and, Mark had three times as many rebounds as Gary.
Together they had 28 rebounds.
To find the how many rebounds did Mark have?
Now, According to the question:
Based on the given conditions:
Let x be the rebounds mark
Mark had three times rebounds as Gary
then, formulate ;
x × (1 + 3)÷ 3 = 28
Solve the equation:
[x × (1 + 3)] / 3 = 28
(x × 4) / 3 = 28
x = 28 × [tex]\frac{3}{4}[/tex]
x = 21
Hence, Rebounds did Mark have is x = 21
The Option C is correct.

Solve for the value of n.
(9n)
(8n+8)
This question is based on the given solving an equation. Therefore, the value of n for (9n) (8n+8) is 0 and -1.
Given:
(9n) (8n+8)
We need to determined the value of n.
According to the question,
It is given that, expression (9n) (8n+8).
For finding the value of n, we would be equate the given expression is equal to zero.
⇒ (9n) (8n+8) = 0
Now, calculating the value of n. We get,
⇒ (9n) (8n)+(9n) (8)
Then, solving above expression further. We get,
⇒ [tex]\bold{72 n^2+ 72n = 0}[/tex]
Now, taking common 72 n. We get,
⇒ 72n (n + 1) = 0
⇒ 72 n = 0 and (n+1) = 0
We get,
n = 0 , -1
Therefore, the value of n for (9n) (8n+8) is 0 and -1.

Seaver Books, a small book publishing company, wrote off the debt of The Learning Center, and the Academy of Basic Education, both small private schools, after it determined that the schools were facing serious financial difficulty. No notice of the action was sent to the schools; Seaver Books simply stopped sending bills. Nearly a year later, The Learning Center was given a large endowment and a government grant. The resulting publicity brought the school to the attention of Seaver Books, which immediately reinstated the account, and sent a new bill to the school, including interest for the entire time the debt was outstanding. No further action was taken regarding the Academy of Basic Education, which was still operational. Did Seaver Books act ethically in reinstating the debt of one client, and not the other? Explain.
Answer:
Seaver Books and Ethical Practice
Yes. Seaver Books acted ethically in reinstating the debt of The Learning Center and not that of the Academy of Basic Education.
Step-by-step explanation:
Writing off a doubtful debt or account is a determination that is done on a case-by-case basis. When a customer's ability to repay a debt is in doubt, the reasonable act will be to write off the debt from the balance to ensure prudent accounting. When the customer's ability to settle the debt is reassessed to be favorable, the debt can be reinstated accordingly. However, it is better to restate the debt after the customer has settled the account and not before. The good news is that customers are not usually informed that their accounts have been written off as doubtful and need not be informed of the reinstatement.
