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
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
It takes billy 6 minutes to walk 1.5 km. How long will it take billy to walk 9km?
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.
Find the product. (-10) (-10) (-10)
1000
-1000

-10,000
the answer is -1000 as -10 cube is -1000
The value of product of (-10)(-10)(-10) is -1000.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts right-hand operand from left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
To determine the product of (-10)(-10)(-10)
⇒ (-10)(-10)(-10)
Multiplying the last two terms and (-) signs cancel out each other,
⇒ (-10)(100)
Multiplying the two terms,
⇒ -1000
Hence, the value of product of (-10)(-10)(-10) is -1000.

Answer:
D
Step-by-step explanation:
The volume for a rectangular prism is given by the formula:
[tex]V=lwh[/tex]
The length is 2h, the width is 9-h, and the height is h. So:
[tex]V=2h(h)(9-h)[/tex]
Multiply the first two terms:
[tex]V=2h^2(9-h)[/tex]
Distribute:

What is the slope of the line x=5
The slope of the line x = 5 is undefined.
What is the slope-intercept form?In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;
y = mx + b
Where:
m is the slope or rate of change.x and y are the points.b is the y-intercept or initial value.Based on the information provided about this line, a linear equation that models it is given by;
y = mx + b
x = 5
This ultimately implies that, this line is a vertical line and as such, it has no slope or an undefined slope. Therefore, the x-intercept is 5 and the slope is undefined.

Which of the following polynomial functions is graphed below
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.

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
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

Answer:
y = -9x - 42Step-by-step explanation:
Perpendicular lines have negative reciprocal slopes
Given line:
y = 1/9x + 6Perpendicular line is:
y = - 9x + b and passes through the point (-7, 0)0 = -9*(-7) + bb = - 42So the line is:
y = -9x - 42Solve for the variable. Show all work. |6x| - 8 = -8
