Car dealerships claim to make most of their money from servicing cars. In a certain month, an Acura dealership sold fifteen less used cars than twice the number of new cars. In the smae month, they serviced fifty more than twelve times the number of new cars sold. If the dealership either sold or services a total of 335 cars that month, how many new cars were sold that month? How many use? How many serviced?

Answers

Answer 1

Answer:

New cars sold = 20,

Used cars sold = 25

Cars serviced = 290

Step-by-step explanation:

In a month they sold fifteen less used cars than twice the number of new cars.

Lets say 'x' number of new cars were sold, then:

The number of used car sold is:

[tex]2\times x-15=2x-15[/tex]

In the same month they serviced fifty more than twelve times the number of new cars sold. So the number of cars serviced is:

[tex]12\times x+50=12x+50[/tex]

Altogether they sold or serviced 335 cars, so the sum of all the cars sold and serviced should be 335:

[tex]x+(2x-15)+(12x+15)=335[/tex]

Solving for 'x' we get:

[tex]x+2x+12x-15+50=335[/tex]

[tex]15x+35=335[/tex]

[tex]15x=335-35=300[/tex]

[tex]x=\frac{300}{15}=20[/tex]

Therefore, the number of new cars sold in that month is 20.

Number of used car sold [tex]=2x-15=2\times 20-15=40-15=25[/tex]

Number of cars serviced [tex]=12\times x+50=12\times20+50=240+50=290[/tex]

We can also cross check by summing them up:

[tex]290+25+20=335[/tex]

solve the quadratic equation by completing the square: x^2+2x-2=0

Answers

ANSWER

[tex]x=\sqrt{3}-1[/tex] or [tex]x=-\sqrt{3}-1[/tex]


EXPLANATION

To complete the square for [tex]x^2+2x-2=0[/tex].

We rewrite the equation to get

[tex]x^2+2x=2[/tex].


We now add [tex](1)^2[/tex] to both sides to get

[tex]x^2+2x+1^2=2+1^2[/tex].

The expression on the Left Hand Side of the equation is a perfect square.


So our equation becomes


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


This gives us,

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


We take square root of both sides to obtain,


[tex]x+1=\pm \sqrt{3}[/tex]

[tex]x=-1\pm \sqrt{3}[/tex]

We split the [tex]\pm[/tex] to obtain,

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

or

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









Answer:

x = √3 - 1 and x = -√3 - 1

Step-by-step explanation:

x^2  +2x - 2 = 0

To solve this equation, keep the variables on one side and constants on the other

x^2 + 2x = 2

Now to complete the square, divide the coefficient of x by 2:

2x ---> coefficient of x is 2

so 2/2 = 1

Now add the square of 1 to both the sides of the equation:

x^2 + 2x + (1)^2 = 2 + (1)^2

which makes it

(x + 1)^2 = 3

To solve it, take square root of both sides which gives

x = √3 - 1 and x = -√3 - 1

Answers

I would say that the answer that best describes the distributive property is "a property of the real numbers that states that the order in which numbers are added or multiplied does not change the value". Distributive property says that when you have a(b+c), you can add b and c together and then multiply by a or multiply b and c by a separately and then add them together after. It does not matter what order you choose to add and multiply in.

you have 5 cups of rice to make bibimbap, a popular Korean meal. The recipe calls for 4/5 cup of rice per serving. How many full servings of bibimbap can you make? How much rice is left over?

Answers

You can make 6 full servings of bibimbap. 1/5 cup of rice is left over.

The number of full servings of bibimbap can you make is dividing the total cups of rice by cups of rice per serving.

You can make 6 whole servings remainder 1 cup of rice

Given:

Total cups of rice = 5 cups

Cups of rice per servings = 4/5 cup

Number of servings of bibimbap can you make = Total cups of rice ÷ Cups of rice per servings

= 5 cups ÷ 4/5 cup

= 5 × 5/4

= (5 × 5) / 4

= 25 /4

= 6 whole servings remainder 1 cup of rice

Therefore, you can make 6 whole servings remainder 1 cup of rice

20+x=25 so I'm doing addition property of equality so what does this mean

Answers

The addition property of equality is the idea we can add some number to both sides of an equation. You must add the same number to both sides to keep things balanced.

It's asking "what number can we add to both sides of this equation so that we isolate x?"

Think of 20+x as x+20. We can rearrange terms since adding in any order doesn't matter (eg: 2+3 = 3+2 = 5)

So we really have this equation: x+20 = 25

We can add -20 to both sides to cancel out the +20 on the left side

x+20 = 25

x+20+(-20) = 25+(-20) ...... add -20 to both sides

x = 5

This is the exact same as subtracting 20 from both sides. So 5 will go where x is, meaning that 20+x = 20+5 = 25

What are the domain and range of the function f(x)=5^x-3 +1

Answers

Final answer:

The domain of the function f(x)=5ˣ-3+1 is all real numbers (-∞, +∞), and the range is all real numbers greater than -2 (-2, +∞).

Explanation:

For the given function f(x) = 5ˣ - 3 + 1, the domain and range can be determined by understanding the behavior of the function's formula. The domain refers to all possible x-values that can be input into the function, and the range refers to all possible y-values that the function can output.

The domain of any exponential function like 5ˣ is all real numbers because you can raise 5 to any power, whether it's positive, negative, or zero. Therefore, the domain of f(x) is (-∞, +∞).

To find the range of the function, we look at the output values. Since exponential functions grow without bound as x increases and approach zero as x decreases (but never actually reaches zero), 5^x will do the same. When we subtract 3 and then add 1, we're simply moving the graph down by 2 units. Thus, where the original function 5ˣ would never be less than 0, after the transformation, the function will never be less than -2. So, the range of f(x) is (-2, +∞).

How much wood $400 be worth after 11 years if it were invested at 4% interest compounded monthly? (Use the formula below and round your answer to the nearest cent.) A(t)=P(1+r/n)^nt

Answers

Here we are given the formula for compound interest as :

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]

Here

A= Amount

P=Principal

r=rate of interest

n=number of times interest is compounded per year

t=time(years)

So we are given

P= $400

r=4% or 0.04

t= 11 years

n= 12

Plugging these values in the formula for compound interest we have,

[tex]A=400(1+\frac{0.04}{12})^{12*11}[/tex]

A= $620.6286

Amount = $620.6

Answer: The final amount after 11 years will be $620.6 .

To find the value of $400 invested at 4% interest compounded monthly for 11 years, use the compound interest formula A(t) = P(1 + r/n)^(nt) and solve for A(t). After calculations, the amount comes to approximately $660.44 when rounded to the nearest cent.

To calculate the future value of $400 invested at 4% interest compounded monthly over 11 years, we can use the compound interest formula provided: A(t) = P(1 + r/n)^(nt). In this formula, P represents the principal amount ($400), r is the annual interest rate (0.04), n is the number of times interest is compounded per year (12 for monthly compounding), t is the number of years the money is invested (11 years), and A(t) is the amount of money accumulated after t years, including interest.

Using the formula:

Calculate the monthly interest rate: r/n = 0.04/12 = 0.003333...Determine the total number of compounding periods: nt = 12 * 11 = 132.Substitute the values into the formula: A(t) = $400(1 + 0.003333...)¹³².Calculate A(t) to find the future value of the investment.

The calculation is as follows:

A(t) = $400(1 + 0.003333...)¹³²

A(t) = $400(1.003333...)¹³²

A(t) = $400(1.6511)

A(t) = $660.44

After rounding to the nearest cent, $400 invested at 4% interest compounded monthly for 11 years would be worth approximately $660.44.

First we write it in the ascending order :

0.037<0.3007<0.307<0.370

So, the largest decimal = 0.370

b. 0.404, 0.044, 0.44

We write it in ascending order :

0.044<0.404<0.440

So, the largest decimal = 0.440

c. 0.05, 0.049, 0.009, 0.1

Ascending order :

0.009<0.049<0.05<0.1

So, the largest decimal = 0.1

d. 2.7, 2.5, 2.75

Ascending order :

2.5<2.7<2.75

So, the largest decimal = 2.75

Prove: line c is parallel to line d
Please help and use the correct postulates and theorems for reasons.

Answers

Final answer:

In this flowchart proof, we utilised the Corresponding Angles Postulate to conclude that line c is parallel to line d. Given that line a is parallel to line b, and angle 7 is congruent to angle 10, we can say that corresponding angles on line c and line d are also congruent, hence proving line c is parallel to line d.

Explanation:

For this flowchart proof, we will use the idea of corresponding angles and the postulate that if a transversal intersects two lines and the corresponding angles are congruent, then the lines are parallel.

Given that line a is parallel to line b.Next, it's given that angle 7 is congruent to angle 10. Assume angle 7 is the angle made by line a and a transversal line, and angle 10 is the angle made by line b and the same transversal.Since line a is parallel to line b and they are cut by a transversal, corresponding angles will be congruent (Corresponding Angles Postulate).We know that angle 7 is congruent to angle 10 (Given).Assume line c and line d are cut by the same transversal as line a and line b, and angle 7 is the corresponding angle to a certain angle on line c, and angle 10 is the corresponding angle to a certain angle on line d. Since angle 7 is congruent to angle 10, the corresponding angles on line c and line d will also be congruent.Hence, line c is parallel to line d (Corresponding Angles Postulate).

The domain for f(x) and g(x) is the set of all real numbers.

Let f(x) = 2x^2 + x − 3 and g(x) = x + 2. Find (f • g)(x).

Answers

Final answer:

The product of the functions f(x) and g(x), (f • g)(x), is found by multiplying the two functions together. The resulting function is 2x^3 + 5x^2 - x - 6.

Explanation:

The question is asking for the product of functions f(x) and g(x), denoted as (f • g)(x). To find (f • g)(x), we simply have to multiply function f(x), which is 2x^2 + x - 3, and function g(x), which is x + 2, together.

Let's do it: (2x^2 + x - 3) * (x + 2). Multiplying these two functions out, we get: 2x^3 + 4x^2 + x^2 + 2x - 3x - 6. Simplifying these, we arrive at 2x^3 + 5x^2 - x - 6.

So, (f • g)(x) = 2x^3 + 5x^2 - x - 6.
