Answer:

Slope=2

Step-by-step explanation:

Slope=rise/run

We can start at 2, 3 (you can start anywhere on the line)

Then go to 3, 5 (you can end anywhere on the line)

Rise=2

Run=1

2/1=2

Slope is 2. The uses up there were examples. It doesn't have to be the exact points.

The equation of the line which is plotted on the graph and passes from the points (2,5) and (-2,-3) is y=2x-6.

The equation of the line is the way of representation of a line in the equation form.

The equitation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.

The formula to find equation of line is,

(y-y₁)={(y₂-y₁)/(x₂-x₁)}(x-x₁)

Here, x and y are the coordinate and subscript (1,2) used for the first and second point.

The points from which the line passes through are (2,5) and (-2,-3). Put the values,

(y-y₁)={(y₂-y₁)/(x₂-x₁)}(x-x₁)

(y-(-2))={(-3-5)/(-2-2)}(x-2)

y+2={-8/-4}(x-2)

y+2=2(x-2)

y+2=2x-4

y=2x-4-2

y=2x-6

Thus, the equation of the line which is plotted on the graph and passes from the points (2,5) and (-2,-3) is y=2x-6.

In which:

In this problem, we have that the initial amount and the growth rate are given, respectively, by:

Hence the amount after t years is given by:

[tex]A(t) = 26000(1.1)^t[/tex]

Then, after 7 years, the amount is:

Answer:

14 units^2

Step-by-step explanation:

Hey there!

In order to find the area of this triangle, we need to find the base and height of the triangle

the base of the triangle is 7 units long and the height of the triangle is 4 units high

Formula for area of triangle: Base x Height x 1/2

7 x 4 x 1/2 --> 28 x 1/2 --> 14

So, the area of this triangle is 14

Now the question is asking to find the area by forming a parallelogram

All you have to do for this is duplicate that same triangle, and mirror it upside down

Then all you would have to do is find the Base and the Height and multiply them together

Answer:

263.76 m^3

Step-by-step explanation:

Using 3.14 as pi

pi * radius^2 * height / 3

3.14 * 6^2 * 7 / 3

3.14 * 36 * 7 /3

3.14 * 252 /3

3.14 * 84

Answer:

b = 17

Step-by-step explanation:

The correct equation is 3b - 6 = 45. You get this by saying the books (b) are 3 dollars each (3b) and you are getting a discount of 6 dollars off (- 6). The total after the discount is 45 dollars. You know have to solve this equation for b (the number of books) to get the answer. When you solve this equation, you get b = 17.

Answer:

3b - 6 = 45 and b = 17

Step-by-step explanation:

3b - 6 = 45 is your equation you get

3b is how many books you bought and the price multiplied by one another, then subtracting 6 gives you the discounted price which is 45

3b - 6 = 45

+6          +6

3b = 51

/3     /3

b = 17

a book costs 17 dollars.

so b = 17

Step-by-step explanation:

The solution of the rational equation [tex]\frac{3}{a + 2} * \frac{2}{a} = \frac{4 a - 4 }{a^2 - 4}[/tex] is a = 3

The equation is given as:

[tex]\frac{3}{a + 2} * \frac{2}{a} = \frac{4 a - 4 }{a^2 - 4}[/tex]

Express a^2 - 4 as  a difference of two squares

[tex]\frac{3}{a + 2} * \frac{2}{a} = \frac{4 a - 4 }{(a + 2)(a - 2)}[/tex]

Cancel out the common terms

[tex]\frac{3}{} * \frac{2}{a} = \frac{4 a - 4 }{a - 2}[/tex]

Factor out 2 from 4a - 4

[tex]\frac{3}{} * \frac{2}{a} = \frac{2(a - 2) }{a - 2}[/tex]

Evaluate the quotient

[tex]\frac{3}{} * \frac{2}{a} = 2[/tex]

Divide both sides by 2

[tex]\frac{3}{1} * \frac{1}{a} = 1[/tex]

Cross multiply

a = 3

Hence, the solution of the equation [tex]\frac{3}{a + 2} * \frac{2}{a} = \frac{4 a - 4 }{a^2 - 4}[/tex] is 3

Answer:

x = 39

Step-by-step explanation:

We know that PRQ is a right triangle, so we use the pythagorean theorem to solve the problem. The theorem states that a^2 + b^2 = c^2. Let's assume that the length of RP is c, the length of PQ is a and x is b. We plug the lengths into the equation and solve it:

80^2 + x^2 = 89^2

6400 +x^2 = 7921

x^2 = 1521

x = [tex]\sqrt{1521}[/tex]

x = 39

The price of Ravi's lunch, before tax and tip was added to the total cost of the meal is $13.19.

Both the tax and the tip paid would increase the cost of the meal. Thus, their dollar value has to be subtracted from the total amount he pays.

Value of the lunch after the tip has been removed = (1 - 0.2) x 17.92 = $14.34

Value of the lunch after the tax has been removed = (1 - 0.08) x $14.34 = $13.19
