The line segment joining A(6, 3) to B(–1, –4) is doubled in length by having half its length added to each end. Find the coordinates of the new ends.
​

Answers

Answer 1

Answer:

(9.5, 6.5) and (-4.5, -7.5)

Step-by-step explanation:

Let the extended points be A' and B' and add the point M as midpoint of AB

Coordinates of M are:

((6 - 1)/2, (3-4)/2) = (2.5, -0.5)

Now point A is midpoint of A'M and point B is midpoint of MB'

Finding the coordinates using midpoint formula:

A' = ((2*6 - 2.5),(2*3 - (-0.5)) = (9.5, 6.5)B' = ((2*(-1) - 2.5), (2*(-4) - (-0.5)) = (-4.5, -7.5)

The Line Segment Joining A(6, 3) To B(1, 4) Is Doubled In Length By Having Half Its Length Added To Each

3x + 1 = 3(x - 1) + 4​

Answers

Simplifying

3x + 1 = 3[x + -1] + 4

Reorder the terms:

1 + 3x = 3[x + -1] + 4

Reorder the terms:

1 + 3x = 3[-1 + x] + 4

1 + 3x = [-1 * 3 + x * 3] + 4

1 + 3x = [-3 + 3x] + 4

Reorder the terms:

1 + 3x = -3 + 4 + 3x

Combine like terms: -3 + 4 = 1

1 + 3x = 1 + 3x

Add '-1' to each side of the equation.

1 + -1 + 3x = 1 + -1 + 3x

Combine like terms: 1 + -1 = 0

0 + 3x = 1 + -1 + 3x

3x = 1 + -1 + 3x

Combine like terms: 1 + -1 = 0

3x = 0 + 3x

3x = 3x

Add '-3x' to each side of the equation.

3x + -3x = 3x + -3x

Combine like terms: 3x + -3x = 0

0 = 3x + -3x

Combine like terms: 3x + -3x = 0

0 = 0

This equation is an identity, all real numbers are solutions.

The rule Rx-axis o is applied to the point (-3,-2). Where is the image in the coordinate

Answers

Answer:

[tex]Image = (-3,2)[/tex]

Step-by-step explanation:

Given

[tex]Point = (-3,-2)[/tex]

Transformation = Rx-axis

Required

Determine the image

When rule Rx-axis is applied to a point (x,y),

The new coordinate point is (x,-y)

In other words, the y coordinate is negated

So, when rule Rx-axis is applied to

[tex]Point = (-3,-2)[/tex]

The image of the point is

[tex]Image = (-3,-(-2))[/tex]

[tex]Image = (-3,2)[/tex]

Ms. Thorson bought a board that was 14 feet long. She cuts off as many pieces as possible that are 9 inches long. What is the length, in inches, of the board that remains?

Answers

Question:

Ms. Thorson bought a board that was 14 feet long. She cuts off as many pieces as possible that are 9 inches long. What is the length, in inches, of the board that remains?

Answer: 6 inches

Step-by-step explanation:

So we know that 14 ft. Is 168 in. all we have to do now is divide.

9/168=18R6

Number of 9 inch pieces possible is 18.

What is division?

The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers

Given,

length of the board = 14 feet
1 feet = 12 inches

14 feet = 168 inches

Length of the piece = 9 feet

Number of pieces cut from board

= 168/9
= 18.67

Number of 9inch pieces = 18

Hence, 18 is the number of pieces that are 9 inches long.

In 2016, the mean score on the AP Biology exam was 3.10, with a standard deviation of 1.05. The mean score on the AP US History exam was a 2.74, with a standard deviation of 1.42. What is the combined mean and standard deviation for these exams

Answers

Answer:

the combined mean and standard deviation for these exams are

mean = 5.84

standard deviation = 1.766

Step-by-step explanation:

Given that;

mean score and standard deviation of AP biology was;

x'1 = 3.10,    S1 =  1.05

mean score and standard deviation of AP US History was;

x'2 = 2.74,    S1 =  1.42

Now combined mean = x'1 + x'2 = 3.10 + 2.74 = 5.84

standard deviation combined = √( S1² + S2²)

= √( (1.05²) + (1.42)²)

= √( 1.1025 + 2.0164)

= √3.1189

= 1.766

Therefore

the combined mean and standard deviation for these exams are

mean = 5.84

standard deviation = 1.766
