Which represents the inverse of the function f(x) = 4x?
h(x) = x + 4
h(x) = x – 4
h(x) = three-quartersx
h(x) = one-quarterx
Answers
By definition, the correct answer is the last option: the inverse of the function f(x) = 4x is h(x)= [tex]\frac{1}{4}[/tex]x.
Definition of inverse functionThe inverse or reciprocal function of f(x) is called another function f⁻¹(x) that satisfies: If f(x)=y , then f⁻¹(y)=x.
To build or calculate the inverse function of any function, one of the ways to do it is to interchange the variables x and y, and use a combination of algebraic methods in order to isolate the variable "y".
Inverse of f(x)=4xBeing f(x)=y=4x, to calculate the inverse, in first place you interchange the variables x and y:
f(y)=x=4y
Isolating the variable y, you get:
h(x)=x÷4= [tex]\frac{1}{4}[/tex]x
Finally, the correct answer is the last option: the inverse of the function f(x) = 4x is h(x)= [tex]\frac{1}{4}[/tex]x.

Anya walked 7/10 km to the bank and then walked 3/4 km to the flower shop. What is the total distance Anya walked? Show your work. Write your answer as a mixed number.
Answers
Answer:
1 and 9/20
Step-by-step explanation:
add your fractions together 7/10 + 3/4
make them have the same denom 14/20 + 15/20
so its 29/20
to get the mixed fraction, divide 29/20 to get 1.45. The 1 is your whole number. Subtract 20 from 29 to get 9, which is what is remaining, and will go over 20.
the answer is 1 and 9/20
work:
7/10km = 14/20km
3/4km = 15/20km
15/20+14/20=29/20km
29/20 as a mixed number is 1 and 9/20.

What is m<1
A. 130°
B. 70°
C. 60°
D. 120°
Answers
Answer:
120 degrees
Step-by-step explanation:
To find m<1 we must first find the other angles.
First, find m<CDB. To do this use the complementary angle 130. So m<CDB=180-130, which means m<CDB=50.
Then find m<2, to do this remember that all triangles equal 180. So to find m<2 solve the equation m<2=180-(70+50), which equals 60 degrees.
Finally find m<1 the same way you found m<CDB, using the complementary angle 2. m<2=180-60, therefore m<1=120.

120

A. The system has no solution.
B. The system has a unique solution at (0,3).
C. The system has a unique solution at (1,5).
D. The system has infinitely many solutions.

Answer:
Option (D)
Step-by-step explanation:
System of equations has been given as,
2y - 4x = 6
y - 2x = 3 [Dividing both sides of the equation by 2]
y = 2x + 3 ------(1) [Slope-intercept for of the equation]
y = 2x + 3 ------(2)
Since, both the equations are same,
System of equations will have infinitely many solutions.

The store bought a table for $200, and sold it for $350. What percentage was the markup? %
Answers
Answer: 175% or 75% more in price
Step-by-step explanation:
There was a 75% of markup in the price.
What is percentage?A percentage is a number that tells us how much out of 100 and can also be written as a decimal or a fraction.
Given that, The store bought a table for $200, and sold it for $350, we need to find the percentage of markup in the price,
percentage of markup in the price =
(final price - original price)/(original price)x100
final price = $350, original price = $200
Markup in price = $350-$200 = $150
percentage of markup in the price = 150/200x100 = 75%
Hence, There was a 75% of markup in the price.

Step-by-step explanation:
Jada plans to serve milk and healthy cookies for a book club meeting
She is preparing 12 ounces of milk and 4 cookies per person
There are 15 people in the club
A package of cookies contains 24 cookies and costs $4.50
A 1-gallon jug of milk contains 128 ounces and costs $3
Let us represents number of people in the club by n
The the ounces of milk = m
The number of cookies = c
Jada's budget in dollars = d
y = 12(15)
She is preparing 4 cookies per person
4n = c
Since A package of cookies contains 24 cookies
She needs = 15 × 4 = 60 cookies
60 ÷ 24 = 2.5
Hence, approximately, she has to buy 3 packages of cookies
She needs = 15 × 12 = 180 ounces of milk
A 1-gallon jug of milk contains 128 ounces
180 ÷ 128 = 1.406
She needs to buy 2 A 1-gallon jug of milk
Note that: from the question
The cost of each jug of milk is $3
The cost of each package of cookies is $4.50
b represents Jada's budget in dollars
b = 2(3) + 3(4.50)

An algebra class normally has y students, but today it is just 2/3 full. Express the number of students in class today terms of y.
Answers
Answer:
2/3y
Step-by-step explanation:
If the class usually has y students and has 2/3 today, it can be represented by 2/3y.
Since multiplying a number or variable by 2/3 makes it 2/3 of the amount, 2/3y will represent the people in the class.
So, in terms of y, 2/3y represents the number of students in class today.
