Answer 2
1) Add 2x² + 3x + 2 and 3x² - 5x - 1

Just do the simple addition. Make sure to add like terms. For instance: Add 3x² with 2x² only, not with 3x and 2.

→ 2x² + 3x + 2 + 3x² - 5x - 1

→ 2x² + 3x² + 3x - 5x + 2 - 1

→ 5x² - 2x + 12) Subtract x² - 4 and 12x² + 4x - 6

The law of subtraction is to subtract the smaller value from the larger value. But it is not necessary that it is always applicable. Its value can be positive, negative and zero (which varies with the given values).

→ x² - 4 - (12x² + 4x - 6)

There will be no change in sign during addition. But if you're doing subtraction change the signs.

→ x² - 4 - 12x² - 4x + 6 [ Product of (-)(-) is (+) and (+)(-) is (-) ]

→ x² - 12x² - 4x - 4 + 6

→ - 11x² - 4x + 2

3) Add 6x² + 3x - 4 and x² - 7

→ 6x² + 3x - 4 + x² - 7

→ 6x² + x² + 3x - 4 - 7

→ 7x² + 3x - 11

4) Add 7x³ + 4x - 1 and 2x² - 6x + 2

→ 7x³ + 4x - 1 + 2x² - 6x + 2

→ 7x³ + 2x² + 4x - 6x - 1 + 2

→ 7x³ + 2x² - 2x + 1

5) Subtract 5x⁴ - 4x³ - 3x - 4 and -2x⁴ - 6x³ + 2x

→ 5x⁴ - 4x³ - 3x - 4 - (-2x⁴ - 6x³ + 2x)

→ 5x⁴ - 4x³ - 3x - 4 + 2x⁴ + 6x³ - 2x

→ 5x⁴ + 2x⁴ - 4x³ + 6x³ - 3x - 2x - 4

→ 7x⁴ + 2x³ - 5x - 4

What is a chord in a circle?

The chord of a circle is defined as the line segment joining any two points on the circumference of the circle. It should be noted that the diameter is the longest chord of a circle that passes through the center of the circle.

Given that a circle, O, where, arcs, XY and XZ are congruent,

We need to find the measure of chord XY in the given circle.

Since, we know that,

If two chord are of the same length, then the two arcs they intercept are congruent.

Therefore,

Arc XY = Arc XZ

solve the literal equation for y.

Answers

Answer:

2B / (mx) = y

Step-by-step explanation:

B = 1/2 mxy

Multiply each side by 2

2B = 2* 1/2 mxy

2B = mxy

Divide each side by mx

2B / (mx) = mxy / (mx)

2B / (mx) = y

Answer:

[tex] \huge y = \frac{2B}{mx} \\ [/tex]

Step-by-step explanation:

[tex]B = \frac{1}{2} mxy \\ [/tex]

Multiply through by 2 to eliminate the fraction

That's

[tex]mxy = 2B[/tex]

Divide both sides by mx to make y stand alone

We have

The Big Motor Works (BMW) is considering a production schedule for cars and trucks over the next two months. They must deliver on time 400 trucks and 800 cars in month one. In month two, their demand is 300 trucks and 300 cars. During each month, at most 1,000 vehicles can be built. Each truck uses two tons of steel and each car uses one ton of steel. During the first month, the steel cost will be $400 per ton. During the second month the cost of steel will go up to $600 per ton. At most 2,500 tons of steel can be purchased in each month. (Steel can only be used in the month it is purchased.) At the beginning of month one, 100 trucks and 200 cars are in inventory. At the beginning of each month a hold- ing cost of $150 per vehicle is assessed. Each car gets 30 mpg, and each truck gets 20 mpg. To meet fuel economy regulations, the vehicles produced each month must average at least 26 mpg. The company wants to minimize its total costs.
a. Formulate a linear program to help BMW determine how many cars and trucks it should produce each month and how many it should keep in inventory each month.
b. Use Solver to find the optimal solution to the linear program from part a. Using a sensitivity report from the Solver solution in part b, answer questions c—g.
c. How many trucks and how many cars should be produced in each month?
d. Suppose the price of steel fell by $25 per ton. What would be the total impact on optimal solution and optimal value?
e. The company just got notified the supply of steel has decreased from 2,500 tons to 2,000 tons. What impact will this have on their production plans?
f. The company is able to add overtime at a cost of $900 per car to increase total production in either month. Should they add overtime in either month? Why or why not?

The equation y = 16.50x describes the amount of money Joey earns, where x is the number of hours he works and y is the amount of money he earns.
The table shows the amount of money Kaylee earns for different numbers of hours worked.
Kaylee’s Earnings
Time (h) 2 5 8 10
Money earned ($) 39 97.50 156 195
(a) How much money does Kaylee earn per hour? Show your work.


(b) Who earns more per hour? Justify your answer.



HELP ME PLEASEEEEE

Answers

Answer:

(a) Kaylee earns $19.50 per hour.

(b) Kaylee earns more money per hour than Joey.

Step-by-step explanation:

x = # of hrs. worked

y = amount of money earned

Joey:

y = 16.50x

Kaylee:

Time (h) 2, 5, 8, 10

Money earned ($) 39, 97.50, 156, 195

y = mx + b; Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

We will be using: (2,39) and (8,156) to find the slope of this table.

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{156-39}{8-2} \\\\m=\frac{117}{6} \\\\m=19.5[/tex]

y = mx + b

y = 19.5x + b

I will be using (2, 39) to find the value of b

(2, 39)

y = 19.5x + b

39 = 19.5(2) + b

39 = 39 + b

-39  -39

0 = b

y = 19.5x + b ==> y = 17.7x + 0 =  OR  y = 19.5x (since the value of b is 0)

(a) The question wants us to find out how money Kaylee earns per hour. Recall that x = # of hrs. worked and y = amount of money earned.

y = 19.5x

She earns $19.50 per hour.

(b)

Joey: y = 16.50x (earns $16.50 per hour)

Kaylee: y = 19.5x (earns $19.50 per hour)

As you can see, Kaylee earns more money per hour than Joey.

I am pretty sure it is a because 2 is half of 4 and 18 is half of 36.

Step-by-step explanation:

Pamela will be 1.7 miles if she walks one-tenth of a mile toward camp.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

At the 1.8-mile marker, Pamela stopped.

We have to determine the mile toward camp if she makes it a mile and a tenth of the way to camp.

Since a tenth of a mile is equal to one mile, if she is heading in the direction of the camp and the 1.8-mile marker is moving forward.

As per the given condition,

So remaining distance would be

⇒ 1.8 - (1/10)

⇒ 1.8 - 0.10

⇒ 1.7

Therefore, she will be 1.7 miles if she walks one-tenth of a mile toward camp.

Answers

Answer:

$60.00

Step-by-step explanation:

The sum of the measures of the angles of a triangle is 180. The sum of the measures of the second and third angles is five times the measure of the first angle. The third angle is 16 more than the second. Let x, y, and z represent the measures of the first, second, and third angles, respectively

Answers

Answer:

x = 30 degrees

y = 67 degrees

z = 83 degrees

Step-by-step explanation:

Let's first set up a few equations. We know:

x + y + z = 180

y + z = 5x

z = y + 16

Let's now solve our equations through substitution. We'll substitute variable z in equations one and two for (y + 16), which is possible thanks to our third equation.

Now, our second equation has become:

y + y + 16 = 5x

So...

5x = 2y + 16

Our first equation is now:

x + y + y + 16 = 180

So...

x + 2y = 180 - 16

And...

x + 2y = 164

Finally...

x = 164 - 2y

Let's take a look at our new first and second equations:

5x = 2y + 16

x = 164 - 2y

Let's substitute again, replacing x in the first equation with (164 - 2y).

Our first equation is now the following:

5(164 - 2y) = 2y + 16

We can apply the Distributive Property to get:

820 - 10y = 2y + 16

So...

-10y - 2y = 16 - 820

-12y = -804

y = 67

Now that we have found y, we can find x and z.

We know that the third angle z is 16 more than the second, y. That was our third equation, z = y + 16.

So, z = 67 + 16.

z = 83.

We know the sum of the y and z is five times the measure of x.

(83 + 67)/5 = 30

To check our work, we can do 67 + 83 + 30 = 180. So we know we are correct.
