Both equations equal 18.6. Just plug in 2.4 for a to check

Answer: In point C.

Step-by-step explanation:

Plane ADB is the plane that contains the points A, D and B.

If you look in the image, you can see that point C also does belong to this plane.

Line EC is the line that connects the points E and C.

Now, remember that Point C does belong to the plane ADB, then the point where the plane ADB and line EC intersect is in point C, because it is a common point to both elements.

6x + 9 = 4x - 3

2x + 9 =-3

Multiply both sides by 2

- 4(5x-7)=-18

5x - 7 = 4.5

Multiply both sides by-4

8 - 10x = 7+ 5x

4 - 10x = 3 + 5x

Multiply both sides by 1

x = 4

5x =- 16

Add to both sides

- 4x

12x + 4 = 20x + 24

Add to both sides

3x + 1 = 5x + 6

Answer:

66

Step-by-step explanation:

Given that:

Total Number of books = 4356

Number of books in a row = number of rows

Let number of rows = b

Then number of books in each row = b

Total number of books = (number of rows * number of books per row

Hence,

4356 = b * b

4356 = b²

Take the square root of both sides

Sqrt(4356) = b

66 = b

Number of books in each row = 66

Answer:

The price that maximizes the revenue is $63.75

Step-by-step explanation:

Analyzing the statement one after the other.

[tex]Initial\ Quantity = 550[/tex]  ---- When ----- [tex]Initial\ Price = \$100[/tex]

When there's a reduction of $1, we have:

[tex]Quantity = 550 + 20x[/tex] and [tex]Price = 100 - x[/tex]

Where x represents the maximum reduction

At this point, we need to calculate the revenue (R)

[tex]R = Quantity * Price.[/tex]

[tex]R = (550 + 20x) * (100 - x)[/tex]

Open Brackets

[tex]R = 55000 - 550x + 2000x - 20x^2[/tex]

[tex]R = 55000 +1450x - 20x^2[/tex]

Differentiate both sides with respect to x

[tex]\frac{dR}{dx} = 0 + 1450 - 40x[/tex]

[tex]\frac{dR}{dx} = 1450 - 40x[/tex]

To maximize revenue;

[tex]\frac{dR}{dx} = 0[/tex]

So:

[tex]1450 - 40x = 0[/tex]

[tex]1450 =40x[/tex]

Solve for x

[tex]x = 1450/40[/tex]

[tex]x = 36.25[/tex]

Recall that:

[tex]Price = 100 - x[/tex]

Substitute [tex]x = 36.25[/tex]

[tex]Price = 100 - 36.25[/tex]

[tex]Price = 63.75[/tex]

Hence:

The price that maximizes the revenue is $63.75

Answer:

-50

Step-by-step explanation:

Luckily for us this one is very simple.

(-5)(10) can also be written as [tex]-5*10[/tex] or with any other multiplicative operator (a symbol that represents multiplication). So this becomes very simple multiplication.

We know that when we multiply a positive number by a negative, the result will be negative - and we also know that 5 times 10 is 50. So our result will be: [tex](-5)(10) = -50[/tex]

Answer:

  (a) 90°, 90°

  (b) 5, 1

  (c) 10°, 20°

  (d) 10°, 20°, 150°

Step-by-step explanation:

You need to consider ways in which each statement might not apply.

(a) An obtuse angle is greater than 90°. If both angles are 90°, then neither is obtuse.

  counterexample: m∠1 = 90°, m∠2 = 90°

__

(b) If the perimeter is 12, the sum of the side lengths must be 6. There are many ways to get two numbers that have a sum of 6. Here's one:

  counterexample: length = 5, width = 1

__

(c) All that is required is that the sum of angles be 30°. They don't have to be equal.

  counterexample: m∠ABC = 10°, m∠CBD = 20°

__

(d) We know the three angles of a triangle have a sum of 180°, but that does not require it to be an acute triangle. A triangle can also be right or obtuse.

  counterexample: m∠P = 10°, m∠Q = 20°, m∠R = 150°

Step-by-step explanation:

The Math.random () function returns a floating-point, pseudo-random number in the range 0–1 (inclusive of 0, but not 1) with approximately uniform distribution over that range — which you can then scale to your desired range.

Answer:

The transformation is " a horizontal translation 4 units to the right " ⇒ (d)

Step-by-step explanation:

Let us revise the translation of a function

Let us look at the graph and choose some points on the f(x) and find their images on y

∵ Point  (1, 2) lies on f(x)

∵ Point (5, 2) lies on y

∵ Point  (3, 8) lies on f(x)

∵ Point (7, 8) lies on y

→ There is no change in the y-coordinates of the points, the change

  only in the x-coordinates

∴ The translation is horizontally

∵  5 - 1 = 4 units ⇒ positive value means to right

∴ f(x) is translated 4 units to the right

∴ The answer is " a horizontal translation 4 units to the right " (d)

Answer: 8.5

Step 1: Multiply by 6 until you reach 51.

6 x 8 = 48.

Step 2: Subtract.

51 - 48 = 3.

Step 3: Convert 3/6 to decimal.

3/6 = .5

Answer = 8.5 times larger

Answer: 8.5

Step-by-step explanation:

Answer:

8,160 times in 8 hours.

Step-by-step explanation: What You must do is Multiply 17 and 60 because there are 60 mins in an hours. You get 1,020 blinks an hour. Now multiply 1,020 and 8 to get 8,160 blinks in 8 Hours.

The first day = 3x

The second day = x

The third day = 2x

720 = 3x + x + 2x

Combine like terms.

720 = 6x

Divide both sides by 6

120 = x

The first day = 3x = 3(120) = 360 miles

The second day = x = 120 miles

The third day = 2x = 2(120) = 240 miles

all the numbers under y are imcresing by the samw number(3)

Let's solve your inequality step-by-step.

4(x+1)<4x+3

Step 1: Simplify both sides of the inequality.

4x+4<4x+3

Step 2: Subtract 4x from both sides.

4x+4−4x<4x+3−4x

4<3

Step 3: Subtract 4 from both sides.

4−4<3−4

0<−1
