All Three Points Displayed Are On The Line. Find An Equation Relating X And Y.

Answers

Answer 1

Answer:

y = 2x - 3

Step-by-step explanation:

The graph is a straight line, thus linear with equation

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, 3) and (x₂, y₂ ) = (6, 9) ← 2 points on the line

m = [tex]\frac{9-3}{6-3}[/tex] = [tex]\frac{6}{3}[/tex] = 2 , thus

y = 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (3, 3 ), then

3 = 6 + c ⇒ c = 3 - 6 = - 3

y = 2x - 3 ← equation relating x and y

Answer 2

The equation whigh relates x and y points on the graph can be expressed in slope-intercept form as y = 2x - 3

The general form of a slope - intercept equation is :

y = bx + cb = slope ; c = intercept

Slope, b = Rise / Run

Rise = 9 - 3 = 6 Run = 6 - 3 = 3

Slope, b = 6/3 = 2

Taking a pair of point on the graph :

(3, 3)

3 = 2(3) + c

3 = 6 + c

3 - 6 = c

c = - 3

Therefore equation can be expressed thus :

y = 2x - 3

5) A cellphone company charges a monthly fee of $34.00, plus $0.05 per text message. If you have at most $52 to spend, how many text messages can you send?

Answers

Answer:

At most you can send 360 text messages while spending at most $52.

Step-by-step explanation:

Let x = money per text message

34.00 + 0.05x ≤ 52

-34.00            -34.00

[tex]\frac{ 0.05x}{ 0.05}[/tex] ≤ [tex]\frac{18}{0.05}[/tex] = 360

The volume of the shaded portion of the cylinder help??????????????

Answers

Answer:

56.52mm²

Step-by-step explanation:

Based on observation, sum of diameters of small circles = diameter of the big circle.

In question, diameter of big circle = 12 mm.

And radius of big circle = 12mm/2 = 6mm

Let the diameter of each small circle be '2a'. So, radius of each small = 2a/2 = a.

=> 2a + 2a = 12mm

=> 4a = 12mm

=> a = 3mm

=> radius of each small circle = 3mm

Area of big circle = πr²

= (3.14)(6mm)²

= 113.04 mm²

Area covered by 2 small circles is: 2 * area of 1 one circle.

=> 2 * π(3mm)² = 18π mm²

=> 56.52 mm²

Shaded area = total area - area of 2 circles = 113.04 - 56.52 mm² = 56.52 mm²

Identify the statement(s) that are both biconditional and false. Three points are not in the same plane if and only if exactly one line passes through them. Exactly one line passes through three points if the points are in an infinite number of planes. an infinite number of planes pass through the same three points if and only if the points are not on the same line. three points on the same line if and only if exactly one plane passes through them. ​

Answers

Answer:

Step-by-step explanation:

1) Three points are not in the same plane if and only if exactly one line passes through them.

It is biconditional and false because more than one plane can pass through three points

2)Exactly one line passes through three points if the points are in an infinite number of planes.

It is biconditional and true because three points on same line will be in more than one plane and if they are not in the same plane then connect them and it will form a triangle which is in only one plane

3). an infinite number of planes pass through the same three points if and only if the points are not on the same line.

It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them

4). three points on the same line if and only if exactly one plane passes through them. ​

It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them

Two polygons are classified as similar when their angles are congruent and their sides are proportional.

If the polygons of this exercise are similar. You can write:

                                   [tex]\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}[/tex]

Then,

                                    [tex]\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}\\ \\ \frac{18}{12}=\frac{x}{20}=\frac{21}{14}[/tex]

A rectangular piece of cheese is 9 centimeters long is 5 centimeters wide. What is the perimeter

Answers

Solution:

We know that:

Perimeter of rectangle = 2L + 2B

Given:

L = 9 cmW = 5 cm

Substitute the values into the expression to find the perimeter.

Perimeter of rectangle = 2L + 2B=> 2(9) + 2(5)=> 18 + 10=> 28 cm

Answer: 28cm

Step-by-step explanation:

The perimeter formula for a rectangle = 2(l + w); where:

length = 9cm

width = 5cm

P = 2(l + w)

= 2(9 + 5)

= 18 + 10

= 28cm

Therefore, the perimeter of the cheese is 28cm
