Which of the sets of ordered pairs represents a function?
P = {(3, 5), (−1, 5), (4, −6), (2, 9)}
Q = {(7, −2), (5, 9), (−1, 8), (5, −3)}
Answer:
P
Step-by-step explanation:
P tells us that the Domain: 3,-1,4,2 doesn't repeat
Q does repeat its Domain: 7,5,-1,5
Reminder that in order for a line of ordered pairs to be a function the domain number Shouldn't repeat, That doesn't mean that the range cant repeat.
Example: (5,-3), (5,9) Not a function
(-1,-6), (7,-6) Function
Out of the two set given, the set of ordered pairs that represents a function is: P = {(3, 5), (−1, 5), (4, −6), (2, 9)}.
What is a Function?A set of ordered pairs that has one exact y-value assigned to each x-value is considered a function.
In set P, all x-values has exactly one y-value, while in set P, the x-value, 5, has two different y-values, 9 and -3.
Therefore, the set of ordered pairs that represents a function is: set P.

Answer:
2³
Step-by-step explanation:
Using the rule of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , thus
[tex]2^{-2}[/tex] × [tex]2^{5}[/tex] = [tex]2^{(-2+5)}[/tex] = 2³ [ = 8 ]
Given the function y=(0.84)t, determine whether the function represents growth or decay and identify the rate of change
Answer:
This function is a decay function and the rate of change is 0.16.
Step-by-step explanation:
We can tell this a decay function because the number in the parentheses is less than 1.
The "parent" function of a decay function is [tex]y = (1-b)^{x}[/tex], where x represents the t and b is the rate of change.
So that means 0.16 is b and 1 - 0.16 resulted in 0.84.

Find two integers whose sum is 19 and product is 90
Answer:
Step-by-step explanation:
The two integers are 10 and 9
10 + 9 = 19
10 x 9 = 90
The two numbers are 9 and 10.
What are integers?A number without a decimal or fractional element is known as an integer, which can be both positive and negative, including zero
Let the two integers be x and y.
Given that, the sum of the integers is 19, therefore,
x + y = 19
x = 19 - y
Given that, the product of the integer is 90:
xy = 90
(19-y)y = 90
19y - y² = 90
y² -19y + 90 =0
y² -10y - 9y + 90 = 0
y(y - 10) -9(y - 10) = 0
(y -9)(y - 10) = 0
y = 9 and y = 10
Hence, the two numbers are 9 and 10.

Topic : Composition of Functions - Worksheet 2 Using f(x) = 5x + 4 and g(x) = x - 3,find: 1. f(g(6)) 2. g(f(-7)) 3. f(f(8)) 4. g(f(x))
Answer:
[tex]f(g(6))=19[/tex][tex]g(f(-7))=-34[/tex][tex]f(f(8))=224[/tex][tex]g(f(x))=5x+1[/tex]Step-by-step explanation:
Considering the functions
[tex]f(x) = 5x + 4[/tex]
[tex]g(x) = x - 3[/tex]
Part 1)
Find
[tex]f(g(6))[/tex]We need to first dertermine [tex]g(6)[/tex]
[tex]g(x) = x - 3[/tex]
Putting x = 6
[tex]g(6) = 6-3=3[/tex]
Then
[tex]f(g(6))=f(3)=5(3)+4=15+4=19[/tex]
Hence,
[tex]f(g(6))=19[/tex]
Part 2)
Find
[tex]g(f(-7))[/tex]We need to first dertermine [tex]f(-7)[/tex]
[tex]f(x) = 5x + 4[/tex]
Putting x = -7
[tex]f(-7) = 5(-7)+4=-35+4=-31[/tex]
Then
[tex]g(f(-7))=g(-31)=(-31-3)=-34[/tex]
Hence,
[tex]g(f(-7))=-34[/tex]
Part 3)
Find
[tex]f(f(8))[/tex]We need to first dertermine [tex]f(8)[/tex]
Putting x = 8
[tex]f(8) = 5(8)+4=40+4=44[/tex]
Then
[tex]f(f(8))=f(44)=5(44)+4=220+4=224[/tex]
Hence,
[tex]f(f(8))=224[/tex]
Part 4)
Find
[tex]g(f(x))[/tex][tex]f(x) = 5x + 4[/tex]
[tex]g(f(x))=g(5x+4)[/tex]
[tex]=(5x+4)-3=5x+1[/tex]
Hence,
[tex]g(f(x))=5x+1[/tex]

Step-by-step explanation:
when perpendicular, u must use m1m2=-1
so , (⅓)(m2)=-1
m2= -3
y-y1=m2(x-x2)
y-1=-3(x-0)
y=-3x+1
Answer:
y = -3x + 1
Step-by-step explanation:
to be perpendicular the multiplication of the gradiens should be -1
m1 × m2 = -1 , m1 = 1/3
1/3 × m2 = -1
m2 = -3
and required equation passes through the point.( 0,1)
y = m2 x + c2
1 = -3 (0) + c2
c2 = 1
so the equation
y = -3x + 1
