Column 2 is labeled y with entries 24, 15, 8, 3.
Answer:
The first two pairs of functions are inverse of each other
Step-by-step explanation:
Inverse functions?
1...................................
f(x) = {(-5, -9), (-3, -4), (0,1), (3,7), (6,13)}
g(x) = {(-9,-5), (-4, -3), (1,0), (7,3), (13,6)}
Yes, this pair is inverse as all points of the functions have inverse values2...................................
f(x) = x + 7 is given
Inverse of f(x) is
x = f'(x) + 7 ⇒ f'(x) = x - 7Since g(x) = x - 7 it is inverse with f(x)
Yes, this pair is inverse as described above3...................................
Data of f(x) and g(x)
x = {2, 3, 4, 5} f(x) = {3, 8, 15, 24}
x = {5, 4, 3, 2} g(x) = {24, 15, 8, 3}
No, as both functions have same domain and rangeexample is f(2) = 3 and g(2) = 3 as per tableMrs. Bell has an interest rate of 4.175% on her house. Mr. Bentley has an interest rate of 4.25% on his house. Which explains who has the lower interest rate?
Answer: Mrs Bell
Step-by-step explanation:
From the question, we are informed that Mrs. Bell has an interest rate of 4.175% = 0.04175 on her house and Mr. Bentley has an interest rate of 4.25% = 0.0425 on his house.
The person who has the lower interest is Mrs Bell. This is because 4.25% is higher than Mrs Bell's interest of 4.175%
Answer:
The answer is D
Step-by-step explanation:
Mrs bell has the lower interest rate because both decimals have a 4 in the ones place, and 1 tenth is less than 2 tenths.

0.18 as a fraction simplest form
Answer:
9/50
Step-by-step explanation:
First, convert the decimal into a fraction. In this case, convert .18 to 18/100. Find a common factor between the numerator and denominator, which in this case, would be 2. Divide both the numerator and denominator by 2 to get 9/50. 9/50 can't be simplified further, so this is your answer.
Answer:
[tex]\frac{9}{50}[/tex]
Step-by-step explanation:
0.18 is [tex]\frac{18}{100}[/tex].
Let's simplify the fraction:
[tex]\frac{18}{100}= \frac{18/2}{100/2}=\boxed{\frac{9}{50}}[/tex]

Carrie sees a dress she wants that usually sells for $109. The dress is on sale at 15% off and sales tax is 6.5%. How much will Carrie need to purchase the dress?
Answer:
$98.67
Step-by-step explanation:
109(.15)= $16.35 You multiply by .15 to find out what 15% of the total (109) is going to be discounted.
109-16.35= 92.65 You subtract the discount from the total to come up with the new total.
92.65(1.065)= 98.67225 =98.67 You take the discounted total, 92.65, and multiply it by 1.065 which represents how you will will be paying for sales tax.

What is the mean of the height 81,88,69,65,87
Answer:
C. 78 cm
Step-by-step explanation:
The mean of any given data set is calculated as sum of all data set divided by the number of data set given.
The data set for the height of Bella's corn given, is 81, 88, 69, 65, 87
Mean height of Bella's corn = [tex] \frac{81 + 88 + 69 + 65 + 87}{5} [/tex]
[tex] mean = \frac{390}{5} [/tex]
[tex] mean = 78 cm [/tex]
You are required to calculate the mean of the height, in other words, the average of the height
The mean of the height is 78
Given height
81, 88, 69, 65, 87
Mean = Total height / number of height
= (81 + 88 + 69 + 65 + 87) / 5
= 390 / 5

what is the value of 10x^3 y^2 when x=-2 and y=-3
Answer:
-720
Step-by-step explanation:
We are given the expression:
[tex]10x^3y^2[/tex]
and asked to evaluate when x= -2 and y= -3.
Therefore, we must substitute -2 for x and -3 for y.
[tex]10(-2)^3*(-3)^2[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Evaluate the first exponent.
⇒ (-2)³ = -2 * -2 * -2= 4*-2= -8
[tex]10(-8)*(-3)^2[/tex]
Evaluate the second exponent.
⇒ (-3)²= -3 * -3= 9
[tex]10(-8)*9[/tex]
Multiply 10 and -8.
[tex]-80*9[/tex]
Multiply -80 and 9.

Points P,Q,R,and S are collinear. Point Q is between P and R, R is between Q and S. If PS=25, and PR=19, what is the value of QR
Answer:
13Step-by-step explanation:
The questions is incomplete. Here is the complete question.
Points P,Q,R,and S are collinear. Point Q is between P and R, R is between Q and S where PQ ≈ RS. If PS=25, and PR=19, what is the value of QR
If points P,Q,R,and S are collinear, this means that the four points lies on the same straight line.
If Point Q is between P and R, then PQ+QR = PR ........... 1
Also if R is between Q and S, then QR+RS = QS ...... 2
Given
PS=25
PR=19
RS = PS-PR
RS = 25-19
RS = 6
Since PQ ≈ RS
Hence PQ = RS = 6
From equation 1;
PQ+QR = PR
substituting the resulting values
6+QR = 19
QR = 19-6
QR = 13
Hence the value of QR is 13

solve for the missing missing variable C=2πr; C=18.84, π=3.14
Answer:
The missing variable r = 3
Step-by-step explanation:
C = 2πr
Where,
C = 18.84
π = 3.14
r= ?
The missing variable is r
C = 2πr
Making r the subject
r = C / 2π
= 18.84 / 2*3,14
= 18.84 / 6.28
= 3
r = 3
The missing variable r = 3
Check:
C = 2πr
18.84 = 2*3.14*3
18.84 = 18.84
