What is the inverse relation of the function whose equation
is y = 3x – 2?
oy = x
o y = 3x + 2
o y = 2x - 3
x + 2
y =
3
Answers
Answer:
The inverse of the function is;
x = (y + 2)/3
Step-by-step explanation:
Here in this question, we shall be calculating the inverse of a function.
The function is;
y = 3x - 2
Firstly, let w = x;
y = 3w -2
y + 2 = 3w
w = (y + 2)/3
Now replace w by x
x = (y + 2)/3
This is the inverse of the function

Answers
Answer:
Irrational
[tex]\sqrt{3}[/tex] = approx. 1.7
Step-by-step explanation:
The square root of 3 is irrational, because 3 is not a perfect square.
For example, 4 is a perfect square, so the square root (2) will be rational.
The square root of 3 is 1.73205080757,

Ruby, her brother, and 3 friends will share the bag of candy she bought. There are 110 candies in the bag. How many will each person get? A. 22 B. 24 C. 26
Answers
Answer: A
Step-by-step explanation: since there’s 110 candies divide it between the 3 friends plus ruby and her brother. So divide 110 by 5 and it will be your final answer
Answer:
A. 22
Step-by-step explanation:
First, you don't want to fall into the trap. The question says Ruby, her brother, AND 3 friends. That means you have to add everyone. 3(friends)+2(Ruby and her brother)=5 people. Then you have to divide. 110/5=22.
So, A.22 candies each.
It takes billy 6 minutes to walk 1.5 km. How long will it take billy to walk 9km?
Answers
Answer:
It will take Billy 36 minutes to walk 9km.
Answer:
[tex]\boxed{\tt 36 \ minutes}[/tex]
Step-by-step explanation:
Let's make a proportion using the following setup:
[tex]\frac{minutes}{kilometers} =\frac{minutes}{kilometers} \\[/tex]
We know it takes Billy 6 minutes to walk 1.5 kilometers.
[tex]\frac{6\ minutes}{1.5\ kilometers} =\frac{minutes}{kilometers}[/tex]
We don't know how long it takes him to walk 9 kilometers, so we can say it takes him x minutes to walk 9 kilometers.
[tex]\frac{6\ minutes}{1.5\ kilometers} =\frac{x\ minutes}{9\ kilometers}[/tex]
[tex]\frac{6}{1.5} =\frac{x}{9}[/tex]
Now, solve for x. To do this, isolate x on one side of the proportion. x is being divided by 9. The inverse of division is multiplication. Multiply both sides of the proportion by 9.
[tex]9*\frac{6}{1.5} =\frac{x}{9}*9[/tex]
[tex]9*\frac{6}{1.5} =x[/tex]
[tex]9*4=x[/tex]
[tex]36=x[/tex]
x= 36 minutes
It will take Billy 36 minutes to walk 9 kilometers.

The formula a = m − n represents the actual cost, a, of an item with original price m after a coupon for n dollars off is applied. Solve the formula for the amount of the coupon. Group of answer choices n=a+m n=m−a n = a − m n = −m − a
Answers
Answer: Option B.
Step-by-step explanation:
The given formula is
[tex]a=m-n[/tex]
where,
a = actual cost of an item.
m = Original price
n = Amount of coupon
We need to solve the formula for the amount of the coupon (n).
In means, we need to isolate n in the given formula.
We have,
[tex]a=m-n[/tex]
Subtract m form both sides.
[tex]a-m=m-n-m[/tex]
[tex]a-m=-n[/tex]
Multiply both sides by -1.
[tex]-(a-m)=n[/tex]
[tex]-(a)-(-m)=n[/tex]
[tex]-a+m=n[/tex]
So, [tex]n=m-a[/tex].
Therefore, the correct option is B.

Which of the following polynomial functions is graphed below
Answers
Answer:
A, the other person was correct
Step-by-step explanation:
The polynomial functions is graphed below is f(x) = (x+ 4)(x- 2)².
What is Function?a mathematical phrase, rule, or law that establishes the link between an independent variable and a dependent variable (the dependent variable).
There are three components that make up a function: a set of inputs, a set of outputs, and a rule that links the elements of the input set to the elements of the output set so that each input is paired with exactly one output.
We have a graph for polynomial function.
We know that the function of graph have solution where the graph touches or passes the x axis.
Here from the graph at x = -4 and at x= 2 the touches and moves upward.
So, the factors of polynomial are (x+ 4) and (x- 2).
Thus, the polynomial function is f(x) = (x+ 4)(x- 2)².
