For this case we have that the fractions have the same denominator, then we can rewrite as:

[tex]\frac {3x + 2 + (2x -5)} {x-1} =[/tex]

We eliminate the parenthesis:

[tex]+*+=+[/tex]

[tex]+*-=-[/tex]

[tex]\frac {3x + 2 + 2x - 5} {x-1} =[/tex]

We add common terms of the numerator:

[tex]\frac {5x-3} {x-1}[/tex]

Thus, the correct expression is option B.

Answer:

Option B

Answer: OPTION B.

Step-by-step explanation:

Given the rational expressions [tex]\frac{3x+2}{x-1}[/tex] and [tex]\frac{2x-5}{x-1}[/tex], we can observe that both have the same denominator, then we can add them.

We must rewrite the denominator [tex]x-1[/tex] and add the numerators. Then:

[tex]=\frac{(3x+2)+(2x-5)}{x-1}[/tex]

Therefore, adding the like terms on the numerator, we get the following sum:

Answer:

Step-by-step explanation:

In order to answer all of these questions we need the position function and the acceleration function.  We will discuss why when we get there.

The velocity function is given; in order to find the position function we have to take the antiderivative of the velocity function.  So in order are the position, velocity, and acceleration functions below:

[tex]s(t)=\frac{1}{3}t^3-\frac{9}{2}t^2+18t+1[/tex]

[tex]v(t)=t^2-9t+18[/tex]

[tex]a(t)=2t-9[/tex]

I know the constant on the position function is 1 because the info given tells me that s(0) = 1.

For the first question, the formula to find the average velocity is as follows:

[tex]v_{avg} =\frac{s(t_{2})-s(t_{1})  }{t_{2}-t_{1}  }[/tex]

To find s(t2) and s(t1) we sub in 8 for t2 and 0 for t1 to get the following:

[tex]v_{avg}=\frac{\frac{83}{3}-1 }{8-0}[/tex]

That simplifies to

[tex]v_{avg}=\frac{10}{3}m/sec[/tex]

The second question wants the instantaneous velocity at t = 5.  We get this by subbing in a 5 for t in the velocity function:

[tex]v(5)=(5)^2-9(5)+18[/tex] and

v(5) = -2.  This means that the velocity of the particle is 2 m/sec, but it is now going in the opposite (or negative) direction.

The third question is asking for the time interval when the particle is moving to the right.  On a velocity/time graph, the x's represent the time and the y's represent the velocity.  If the "y" values are positive, then the velocity is positive and that means the object is moving to the right.  Where the "y" values are negative, that means that the velocity is negative and the object is moving to the left.  To find the answer to this problem we think about the positive and negative y values.  Because this is a parabola, I know that the places where the graph goes through the x-axis is where the velocity changes from positive to negative and back to positive.  In order to find those places where the graph goes through the x-axis I have to factor the velocity function.  When I throw that into the quadratic formula on my calculator I get that x = 3 and x = 6.  Completing the square on the velocity function gives me a vertex of [tex](\frac{9}{2},-\frac{9}{4})[/tex]

Because the y value of the vertex is negative, that means that the values of x from negative infinity to x = 3 give positive velocity values, between x = 3 and x = 6 the values of the velocity are negative, and from x = 6 to x = positive infinity the velocity is positive again.  

So to sum up question 3, the particle is moving to the right on the intervals

(-∞, 3] and [6, ∞)

The fourth question is really tricky.  It requires you to remember some of your Physics and how velocity and acceleration vectors are related.  If the acceleration and the velocity both have the same sign, whether it be positive or negative, the object is speeding up.  If the acceleration and velocity vectors have opposite signs, one positive and one negative, then the object is slowing down.  We already know that from negative infinity to 3 the velocity is positive, so let's check the acceleration values in that interval.  I only need to test one number, so let's test a(2).  

a(2) = 2(2) - 9 and a(2) = -5

-5 means the object is slowing down here since the velocity is positive and the acceleration is negative.  

Let's test the interval between 3 and 6.  Let's test a(4).

a(4) = -1

Between the interval of 3 and 6 seconds, the velocity is negative.  Since the acceleration is also negative, the object is speeding up between the time interval [3, 6].

We already found that from the left of t = 3, the object was slowing down; so it would also be slowing down to the right of t = 6.

Phew!  That's it!  We're done!

First you must distribute the 2x to the numbers inside the parentheses

(2x * x) + (2x * -1) = 3

[tex]2x^{2}[/tex] - 2x = 3

To make this a quadratic equation you can solve bring the 3 over to the left side of the equation by subtracting it to both sides

[tex]2x^{2}[/tex] - 2x - 3 = 0

Use the quadratic equation to solve this (image of the quadratic equation is below)

Remember that quadratic functions are set up like so:

[tex]ax^{2} +bx +c = 0[/tex]

That means that in this equation...

a = 2

Answer:

The equation can be used to find the amount of time Hiroshi spends on his math homework is 1/4 (30 + 60 + x) = x ⇒ answer a

Step-by-step explanation:

* Lets read the problem and take the information to solve the problem

- Hiroshi spends 30 minutes on history homework

- Hiroshi spends 60 minutes on English homework

- Hiroshi spends  x minutes on math homework

* From these information

- The total homework time is (30 + 60 + x) minutes

- Hiroshi spends one fourth of his total homework time on math

- The time of math homework is 1/4 the total homework time

∵ The total homework time = (30 + 60 + x)

∵ The time of math homework is 1/4 the total homework time

∴ The time of math homework = 1/4 (30 + 60 + x)

- Then equate the times of math homework

∵ Hiroshi spends  x minutes on math homework

∵ The time of math homework = 1/4 (30 + 60 + x)

∴ 1/4 (30 + 60 + x) = x

* The equation can be used to find the amount of time Hiroshi

Final answer:

To cover a 81 meter by 117 meter field with pallets of grass, we calculate the area in square yards and then the number of pallets needed. Each pallet covers 90 square yards and costs $210. The total cost is $27,300.

Explanation:

The question involves calculating the cost to cover a rectangular field with pallets of grass. The field measures 81 meters by 117 meters. We will first need to calculate the area of the field in square meters and then convert it to square yards since the pallets cover an area in square yards. Then, we'll find out how many pallets are needed and multiply by the cost per pallet to get the total cost.

First, let's find the area of the field in square meters:

Area = length × width = 81 m × 117 m = 9,477 m²

Now, convert square meters to square yards, using the hint that 1 yard ≈ 0.9 meters. Since the area is given in meters and we have that 1 m² = (1/0.9)² yd², we can use:

Area in yd² = 9,477 m² × (1/0.9)² = 9,477 m² × 1.23456790123 yd²/m² ≈ 11,700 yd²

Each pallet of grass covers 90 square yards, so we divide the total area by the coverage per pallet:

Number of pallets = Area in yd² / Coverage per pallet = 11,700 yd² / 90 yd²/pallet ≈ 130 pallets

Finally, we multiply the number of pallets needed by the cost per pallet to get the total cost:

Total cost = Number of pallets × Cost per pallet = 130 × $210 = $27,300

The total cost to cover the field with pallets of grass will be $27,300.

Final answer:

To cover a 81m by 117m field with pallets of grass, you need approximately 130 pallets, resulting in a total cost of $27,300.

Explanation:

The question asks us to calculate the cost to cover a rectangular field with grass pallets. The field's dimensions are 81 meters by 117 meters. First, we need to calculate the field's area in square meters and then convert that area to square yards as the pallet covers a certain number of square yards. Lastly, we will determine the total cost by multiplying the number of pallets needed by the cost per pallet.

To convert the field area from square meters to square yards, we use the approximation given that 1 yard is almost equal to 0.9 meters. So, we have:

To find out how many pallets we need:

The cost to cover the entire field is therefore:

Answer:

  4b + 5

Step-by-step explanation:

Equation C tells us ...

  a = 4b + 5

so, the value "4b +5" can be substituted for "a" in Equation D.

_____

In algebra, things that are equal are interchangeable. One can always be substituted for the other.

the value of 'a' that can be substituted into Equation D to solve the system of equations is 19.

To solve the system of equations given by Equation C: a = 4b + 5 and Equation D: a = 6b \\- 2, we are looking for a value of a which satisfies both equations simultaneously. Since equations C and D both define 'a' in terms of 'b', we can set them equal to each other to find the value of 'b', and then use that value to find 'a'.

Step 1: Set Equation C equal to Equation D, since they both equal 'a'.
4b + 5 = 6b - 2.

Step 2: Solve for 'b'.
Subtract '4b' from both sides: 5 = 2b \\- 2.
Add 2 to both sides: 7 = 2b.
Divide both sides by 2: b = 7/2 or 3.5.

Step 3: Substitute the value of 'b' into either Equation C or D to find 'a'.
Using Equation C: a = 4(3.5) + 5 = 14 + 5 = 19.

Therefore, the value of 'a' that can be substituted into Equation D to solve the system of equations is 19.

  17.4 - 14.8 = 2.6 . . . . cents per kWh

Then to find the savings a household would experience, we multiply this savings rate by the monthly usage rate of the household.

  530 kWh × $0.026/kWh = $13.78

  730 kWh × $0.026/kWh = $18.98

So for household usage between these energy values, the savings (x) using Company D will satisfy ...

  13.78 ≤ x ≤ 18.98
