Answer:
25/4
Step-by-step explanation:
7 can also be 7/1. Now you have 7/1-3/4. Multiply the denomiator to make them the same so you can subtract. 1*4=4 and 7*4= 28. Now you have 28/4-3/4. Subtract the numerators. 28-3=25. Your answer is 25/4. (6.25 if you need it in decimal form)

Which set of ordered pairs represents a function?

{(–3, 1), (6, 3), (–3, 2), (–3, –3), (1, –1)}
Answers
Answer: {(2,-2), (1,5), (-2,2), (1,-3), (8,-1)}, and {(3,-1), (7,1), (-6,-1), (9,1), (2,-1)
Step-by-step explanation: In order for a given relation to be a function, there can only be 1 x-value that can repeat. The y-values on the other hand can repeat an infinite amount of times. In the last 2 relations, you have (-2,-5), (-2,9) and (-3,1), (-3,2), and (-3,-3). You can also graph these relations and do a vertical line test with your pencil drawing a straight line downward and you'll notice that you will touch the graph more than 1 time. The first 2 relations if you were to graph them and do a vertical line test by using a pencil or pen, you'll notice that you will touch the graph once which shows you that you have a relation that is indeed a function.
Hope this explanation helps.

Part B: Write an equation that can be used to find the value of the piano, v, after t years
Answers
Answer:
Part A would be: 3, $2560 & 4, 2048 I am pretty sure
Step-by-step explanation:
20% of 3,200 = 640
3,200-640= 2,560
then
20% of 2,560 = 512
2,560-512 = 2,048
hope this helps! :)
Part A: The first answer is correct, or (3, $2560) & (4, $2048)
Part B: V = 5,000(0.8)^t
5000 is the original price, 0.8 shows the value going down 20%, and t shows how many years.

Given info:- In ∆ABC, right-angled at c in which AB = 10in, BC = 26 in and we have to find out the measure of AC = ?
Explanation:
In right angled ∆OCB, AC ⟂ CB,
AB² = AC²+CB²
[By Pythagoras theorem]
(10)² = AC²+(26)²
10*10 = AC²+(26*26)
100 = AC²+676
AC² = 676-100
AC² = 576
AC = √(576)
AC = 24 in.

A father is 35 years more than his son’s age. After 5 years the father’s age will be twice of his son’s age.Find the present age of both.
Answers
The son is 30 years and the father is 65 years.
Let x represent the present age of the son and y represent the present age of the father.
Hence:
y = x + 35
-x + y = 35 (1)
In 5 years time:
y + 5 = 2(x + 5)
y + 5 = 2x + 10
-2x + y = 5 (2)
Solving equations 1 and 2 simultaneously gives:
x = 30, y = 65
The son is 30 years and the father is 65 years.

Son = 30 years
Father = 65 years
Present Details:
Son: "s" years (lets consider son's present age to be s)
Father: "s + 35" (father is 35 years older than the son)
After 5 years:
Son: "s + 5" [son will be 5 years older]
Father: 2(s + 5) [twice the son's age] and (s + 35) + 5 = (s + 40) years
Solve father's age simultaneously:
2(s + 5) = (s + 40)2s + 10 = s + 402s - s = 40 - 10s = 30⊕ Thus, the Son is 30 years old.

Step-by-step explanation:
The remainder theorem tells you that the remainder from division f(x)/(x -k) is f(k). You want the value of k such that ...
f(k) = -15
