Identity whether the following points are collinear . (2 , 3 ) (4 , 7 ) (8 , 11 )

Answers

Answer:

not collinear points

Step-by-step explanation:

If the points are collinear ( lie on the same line ) then the slopes between adjacent points will be equal.

Calculate the slope m using the slope formula

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

with (x₁, y₁ ) = (2, 3) and (x₂, y₂ ) = (4, 7)

m = [tex]\frac{7-3}{4-2}[/tex] = [tex]\frac{4}{2}[/tex] = 2

Repeat with (x₁, y₁ ) = (4, 7) and (x₂, y₂ ) = (8, 11)

m = [tex]\frac{11-7}{8-4}[/tex] = [tex]\frac{4}{4}[/tex] = 1

Since the slopes are not equal then the points are not collinear

Find the x- and y-intercepts of the graph of 3x + 2y = 20. State your answers as
whole numbers or as improper fractions in simplest form.

Answers

the answer is in the picture

The x-intercept is given by the coordinates as (x, 0)

i,e y = 0

The y-intercept is given by the coordinates as (0, y)

i.e x = 0

The x-intercept of the graph of 3x + 2y = 20 is at x = 20/3

The y-intercept of the graph of 3x + 2y = 20 is at y = 10

What are coordinates in a graph?

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

3x + 2y = 20

The x-intercept is given by the coordinates as (x, 0)

i,e y = 0

The y-intercept is given by the coordinates as (0, y)

i.e x = 0

Now,

3x + 2y = 20

Putting x = 0 in (1) we get the y-intercept.

3x + 2y = 20

3x0 + 2y = 20

0 + 2y = 20

2y = 20

Divide both sides by 2.

y = 20/2

y = 10

Putting y = 0 in (1) we get the x-intercept.

3x + 2y = 20

3x + 2 x 0 = 20

3x + 0 = 20

3x = 20

Divide both sides by 3.

x = 20/3

Thus,

The x-intercept of the graph of 3x + 2y = 20 is at x = 20/3

The y-intercept of the graph of 3x + 2y = 20 is at y = 10

PLS HELP a parabola has the equation y = 4x^2 + bx -2 and the equation for the axis of symmetry is x = -1.

Answers

Answer:

Step-by-step explanation:

Remark

Unless you know calculus, the only way to solve this is by completing the square.

Solution

y = 4x^2 + bx - 2

y = 4(x^2 + b/4 ) - 2

y = 4(x^2 + b/4 + (1/2b/4)^2 ) - 2 - 4*(b/8)^2

y = 4(x^2 + b/4 + (b/8)^2 ) -  2 - b^2/16

y = 4(x + b/8)^2 - 2 - b^2/16

Now what you want to happen is to give b/8 a value of 1 so that when x is put in -1 you get 0 for  what is inside the brackets.  

b/8 = 1

b = 8

y = 4(x + 1)^2 - 2 - (8)^2 / 16

y = 4(x + 2)^2 - 2 - 4

y = 4(x + 1)^2 - 6

The vertex is at (-1, - 6)

The axis of symmetry  is x = - 1

Note

This could have been done a lot shorter just by realizing that the number inside the brackets had to be + 1 as in (x + 1). But then you would not have been able to know the minimum value for y which is - 6

Answer:

15%

Step-by-step explanation:

1. Subtract final value from starting value

65 - 55.25 = 9.75

2. Divide 9.75 by original number

9.75/65 = 0.15

3. Multiply quotient by 100 to get percentage

0.15 x 100 = 15%

For a school fundraiser, Jessica will make T-shirts. She will order T-shirts and print graphics on them. Jessica must spend $255 on a printing machine and
$6.80 per shirt for the blank shirts, Ink, and other supplies.
Part
What is the maximum number of T-shirts Jessica can make with a budget of $1,000?
Explain your answer or show your work:

Answers

You’d need to start by subtracting initial cost from the budget, so

1000-255= 745

You then divide the 745 by the cost of making each shirt,

745/6.80= 109.56

Since you can’t make .56 of a shirt, and the budget says we can’t round up, you can only make 109 shirts.

the answer is B i believe

The circumference of the circle is 32 inches. The correct option is B.

What is circumference?

The circumference is the length of the line by which the circle is made. The circle is defined as the locus of the point traces around a fixed point called as the center and is equidistant from the outer trace.

Given that a circle has a diameter of 10.2 inches. The radius of the circle is 5.1 inches.

The circumference of the circle is calculated by the formula,

C = 2πr

C = 2 x π x 5.1

In an endurance race, Alyson rode her bicycle 7 miles less than Jeff. Together they rode 39 miles. How far did Alyson ride?

Answers

Answer:

Distance cover by Alyson = 16 miles

Step-by-step explanation:

Given:

Distance cover together = 39 miles

Assume;

Distance cover by Jeff = a

Distance cover by Alyson = a - 7

Find:

Distance cover by Alyson

Computation:

a + (a - 7) = 39

2a - 7 = 39

2a = 46

a = 23

Distance cover by Alyson = a - 7

Distance cover by Alyson = 23 - 7

Distance cover by Alyson = 16 miles

A piece of copper tubing is in the shape of a hexagonal prism. The area of the base of the prism is 3 square centimeters. The volume of the prism is 51 cubic centimeters. What is the height of the tubing? ​

Answers

Answer: 17 cm

Step-by-step explanation:

For a regular figure where the area of the base is B, and the height is H, the volume is calculated as:

V = B*H

Here we know that the base of the prism is B = 3 cm^2, and the volume of the prism is 51 cm^3

Then:

B = 3cm^2

V = 51cm^3

If we replace those in the equation above, we get:

51 cm^3 = (3cm^2)*H

Solving this for H gives:

(51 cm^3)/(3 cm^2) = H = 17 cm

The height of the tubing is 17 cm
