Answers

Answer:

this would be 12/6+(-1/6)

Step-by-step explanation:

if you want to solve it would be 11/6, or "1 5/6ths"

we need to first find the common denominator, which is 6, but since we multiplied the bottom by 2, we multiply the top by 2. next we just subtract the values, and i put the 1 because there is only one "6" that goes in to the bottom ,and 5 is left over.

Ralph is leasing a car worth $24,000 for three years. his leasing company says that the car ralph is leasing will only be worth $16,000 at the end of his lease. approximately what percentage of the car’s original value will ralph need to pay as part of his lease?

Answers

The percentage of the car's original value will be 33%

We have given that the car was worth $24,000, being this the original value, after three years the car will be worth $16,000.

Therefore to find the percentage of the car’s original value will Ralph need to pay as part of his lease, We have to find  the difference between the original value and the new value.

So the difference between the original value and new value is,

24,000-16,000= $8000.

What is the percentage?

A percentage is a number or ratio expressed as a fraction of 100.

And the percentage can be calculated dividing the difference by the original value of the car.

[tex]\frac{8000}{24000}\times 100=33.3\%[/tex]

Answer:

x = 7, x = -7

Step-by-step explanation:

Hi there!

We are given the following equation:

x²-49=0

And we want to solve it for x

x²-49 is actually written in the difference of squares formula, which is a²-b²=(a+b)(a-b)

In this case, x² and 49 represent a² and b², so we'll need to find a and b

For x², we need to find which number or variable multiplies itself to equal x²; in this case, it will be x (x*x=x²)

For 49, we need to find which number multiplies itself to equal 49; in this case, it will be 7 (7 * 7 = 49)

Thus, a in this case is x, and b is 7

Now substitute these values into the formula.

(a+b)(a-b)= (x+7)(x-7)

Now set (x+7)(x-7) (which is x²-49, just expanded out) equal to 0

(x+7)(x-7)=0

Now using zero product property, split and solve:

x+7=0

subtract 7 from both sides

x=-7

x-7=0

Add 7 to both sides

x=7

Therefore, the answer is x = 7, x = -7 (there are 2 answers here that work!)

if f(x)=2x+1, what would be the first step to find f(1)

Answers

Answer:
First step: plug 1 in for x
f(1)=3

Explanation:
We are given the function
f(x)=2x+1
We want to find f(1). Therefore, the first step would be plugging 1 in for each x.
f(1)=2(1)+1
If we want to find the answer, solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
Multiply 2 and 1.
f(1)=2+1
Add 2 and 1.
f(1)=3

The first step is plugging 1 in for x. The final answer is f(1)=3

Answer:

We are given a defined function: f(x) = 2x + 1. This function is the same as saying y = 2x + 1 (y and f(x) are used interchangeably and are the same value - just a different way of representing it). Because we want to find f(1), math states that if you replace one variable with a value, you must replace all of the same variables with that value. Because of this, if we change f(x) to f(3x), we are declaring that the variable x has a value of 3x. Or, if we were to change f(g) to f(3g + 4), we would then be replacing the g's in the function with 3g + 4.

Using these examples, we can the find the value of f(1). We would simply replace the x-values in the function with the value of 1 and then take any operations necessary - be sure to use PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

[tex]f(x) = 2x + 1\\\\f(1) = 2(1) + 1\\\\f(1) = 2 + 1\\\\f(1) = 3[/tex]

Therefore, the first step to solve the problem would be to replace the x-values in the equation with the value of 1. From there, you would simplify your equation and find what the value of the function is if evaluated at f(1).

Three months later some vehicles were sold and new models have been brought into the Liberty Bike Shop. Now, there are a different number of bicycles, tandem bicycles, and tricycles in the shop. There are a total of 135 seats, 118 front handlebars (that steer the bike), and 269 wheels.

Answers

Answer:

There 68 bicycles , 33 tricycles and 17 Tandem bicycles

Step-by-step explanation:

Let B be the no. bicycles , TB be the no. of tandem bicycles and C be the no. of tricycles

No. of seats in 1 bicycle = 1

No. of seats in B bicycle = B

No. of seats in 1 Tandem bicycle = 2

No. of seats in TB Tandem bicycle = 2TB

No. of seats in 1 Tricycle = 1

No. of seats in C Tricycle = C

We are given that There are a total of 135 seats

So, B+2TB+C=135 ----1

Similarly

There are total 118 front handlers

So,1B + 1TB + 1C = 118 ----2

There are total 269 wheels

So,2B + 2TB + 3TR = 269

Substract 1 from 2

B+2TB+C-B-TB-C=135-118

TB=17

Adding 1 and 2 and substracting from 3

[2 - (1+1)]B + [2- (2+1)]TB +  [3- (1+1)]C = 269-253

- 1x17 +C= 16

C= 16 + 17 = 33

Replacing in eq. 32

1B + 17 + 33 = 118

B = 118 - 17 - 33 =  68

Hence There 68 bicycles , 33 tricycles and 17 Tandem bicycles

6 unit cubes and 18 smaller cubes of volume 1/27 cubic inches

=========================================================

Explanation:

Block A = unit cube that has side length of 1 inch

Block B = cube that has side length 1/3 inch

Block B has a volume of (1/3)*(1/3)*(1/3) = 1/27 cubic inches

If we have 180 of block B, then

180*(1/27) = 180/27 = 6.6667 approximately

The first 6 before the decimal point tells us we have 6 block A's. This is the same as saying that we have 6 cubic inches so far.

The 0.6667 at the end means we have 0.6667*27 = 18.0009 = 18 block B's

So we have 6 unit cubes (block A) and 18 smaller cubes (block B) that have a volume of 1/27 cubic inches

--------------

Another way to look at it

180/27 = (162+18)/27

180/27 = 162/27+18/27

180/27 = 6+18/27

180/27 = 6 remainder 18

The last line can also be found through using long division.

The 6 refers to 6 unit cubes and the remainder 18 is the left over 18 smaller blocks.

The material needed for the kite is the area of the kite

The amount of material needed for the entire kite is 48 square inches

How to determine the amount of material

The given parameters:

KI =6 inches

ET = 8 inches

KT=10 inches

Area of ΔKIT = 17 square inches

Start by calculating the area of the bottom triangle using:

Area = 0.5 * Base * Height

So, we have:

Area = 0.5 * KI * KT

This gives

Area = 0.5 * 6 * 10

Area = 30

The amount of material used is then calculated as:

Material = Area of the bottom triangle + Area of ΔKIT

This gives

Material = 30 + 17

Material = 47

This is approximately 48

Hence, 48 square inches of material is used for the entire kite

Answer:

[tex]f^{-1}(x)=\sqrt{x+1}-3[/tex]

Step-by-step explanation:

We have the function:

[tex]f(x)=y=x^2+6x+8[/tex] with the domain restriction [tex]\{x\geq -3\}[/tex].

And we want to find the inverse of our function.

To find the inverse of our function, we take the following steps:

1) Swap x and y. 2) Solve for y.

Therefore, our inverse will be:

[tex]x=y^2+6y+8[/tex]

First, let's subtract 8 from both sides. So:

[tex]x-8=y^2+6y[/tex]

To solve for y, we can complete the square. To complete the square, we:

1) Divide the coefficient of the b term by 2. 2) Square that. 3) Add that number to both sides.

Our b term is 6. [tex]6/2=3[/tex], and [tex]3^2=9[/tex]. So, we will add 9 to both sides. This yields:

[tex](x-8)+9=(y^2+6y+9)[/tex]

Simplify the left. Complete the square on the right. So:

[tex]x+1=(y+3)^2[/tex]

Take the square root of both sides and solve for y:

[tex]y+3=\sqrt{x+1}\Rightarrow y=\sqrt{x+1}-3[/tex]

Subtract 3 from both sides. So, our inverse is:

[tex]f^{-1}(x)=\sqrt{x+1}-3[/tex]

Part 2)

See below for graph.

Here is also a good time to reinforce the idea of inverses. Notice that the domain of our original function f(x) is [tex]x\geq-3[/tex]. So, this means that the range of f(x) is (looking at the graph) is [tex]y\geq-1[/tex].

When we find the inverse, we will flip the domain and range. Therefore, the domain of our inverse function will be the range of our original function, and the range of our inverse function will be the domain of our original function.

From the graph, we can see that f⁻¹(x) has a domain of [tex]x\geq-1[/tex] and a range of [tex]y\geq -3[/tex]. Therefore, their domain and range are indeed opposites.

And we're done!
