The slope of the  line passing through the points (3, 3) and (0, -6) is 3.

What is Slope of Line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

We need to find the slope of line passing through points (3, 3) and (0, -6)

Plug in the values in formula.

m=-6-3/0-3

m=-9/-3

m=3

Hence, the slope of the  line passing through the points (3, 3) and (0, -6) is 3.

If x= 7 - 4√3 then find the value of (a) (x+1/x) rais to 2 b) x rais 2+1/x rais to 2

Answers

The equation x = 7 - 4√3 is a radical expression, and the value of the radical expression is [tex](x + \frac 1x)^2 = 3650401 -2107560\sqrt 3[/tex]

How to solve the expressions?

The equation is given as:

x = 7 - 4√3

So, we have:

[tex](x + \frac 1x)^2 = (7 - 4\sqrt 3 + \frac{1}{7 - 4\sqrt 3})^2[/tex]

Take the LCM

[tex](x + \frac 1x)^2 = (\frac{49 -56\sqrt3 + 48}{7 - 4\sqrt 3})^2[/tex]

Evaluate the like terms

[tex](x + \frac 1x)^2 = (\frac{97 -56\sqrt3 }{7 - 4\sqrt 3})^2[/tex]

Rationalize

[tex](x + \frac 1x)^2 = (\frac{(97 -56\sqrt3)(7 - 4\sqrt 3) }{49 -48})^2[/tex]

Evaluate the difference

[tex](x + \frac 1x)^2 = ((97 -56\sqrt3)(7 - 4\sqrt 3))^2[/tex]

Expand

[tex](x + \frac 1x)^2 = (679 -388\sqrt 3 -392\sqrt 3 + 672)^2[/tex]

Evaluate the like terms

[tex](x + \frac 1x)^2 = (1351 -780\sqrt 3 )^2[/tex]

Expand

[tex](x + \frac 1x)^2 = 1825201 +1825200 -2107560\sqrt 3[/tex]

[tex](x + \frac 1x)^2 = 3650401 -2107560\sqrt 3[/tex]

Hence, the value of the radical expression is [tex](x + \frac 1x)^2 = 3650401 -2107560\sqrt 3[/tex]

What is Three dimensional shape?

a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.

Given that the roof of a clock tower is a pentagonal pyramid.

a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point

Each side of the base is 7 ft long.

The slant height is 9 ft.

Hello!

The missing angle is 60°, and is found by subtracting 90° and 30° from 180°.

Using basic triangle theorems of a 30° - 60° - 90° triangle, we know that the leg opposite to 30°, x, is one-half of the hypotenuse.

So:x = 0.5(12)x = 6.

The value of x is 6.

The leg opposite to 60° is √3 times the leg opposite to 30°.

Answers

Answer:

B. (2, 4)

Explanation:

Given equations:

a) y = x + 2

b) y = 3x – 2

Solve them simultaneously:

x + 2 = 3x – 2

x - 3x = -2 - 2

-2x = -4

x = 2

Then find y = x + 2 = 2 + 2 = 4

Solution: (x, y) = (2, 4)

Answer:

(2,4)

Step-by-step explanation:

substitute the value of y x+2 = 3x-2

solve the value of x  x = 2

substitue the value of x into one of the equations y = 2+2

solve for y value y = 4

$75 before tax. Disc: 10% Tax: 7%, Tip: 20% what's the total PLEASE help

Answers

Answer:

  total: $86.68

Step-by-step explanation:

The value of each change is found by multiplying the base amount by the percentage change. The result is rounded to the nearest cent. Here, we're applying 3 changes. In order to make sure they're rounded properly, we need to apply them in order

__

discount

The discount amount is ...

  discount = bill × 10% = $75.00 × 0.10 = $7.50

The discounted amount is ...

  bill - discount = $75.00 -7.50 = $67.50

__

tax

The tax amount is ...

  tax = discounted bill × tax rate = $67.50 × 0.07 = $4.725 ≈ $4.73

The bill with tax added is ...

  discounted bill + tax = $67.50 +4.73 = $72.23

__

tip

The tip is apparently added to the amount after tax, so the amount of the tip is ...

  tip = taxed bill × 0.20 = $72.23 × 0.20 = $14.446 ≈ $14.45

The bill with tax and tip added is ...

  total bill = $72.23 +14.45 = $86.68

_____

Additional comment

At each stage, the amount can be found by using the multiplying factor (1+p), where p is the percentage change. All three factors applied gives a result of ...

  75×(1-0.10)(1+0.07)(1+0.20) = 75×0.9×1.07×1.2 = 86.67

You will note this differs by a penny from the amount calculated above. That is a consequence of rounding up both the tax and the tip.

A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.

Here, given points;

Now,

    d = (y₂ - y₁)/(x₂-x₁)

    d = (-4.5 - (-3.75))/(2 - 1)

     d = -0.75 / 1
