In the coordinate plane, find the distance between the points using absolute value.
alukav5142 [94]

Answer:

The distance between the two points is 8 units

Step-by-step explanation:

In the given figure

∵ The coordinates of the 2 points are (4, 5) and (4, -3)

∴ x1 = 4 and y1 = 5

∴ x2 = 4 and y2 = -3

∵ Their x-coordinates are equal

→ That means the distance between them is vertical

∴ The length of the vertical distance between two points is

   the difference between the y-coordinates of the points

∵ The distance between them = Iy2 - y1I

∵ y1 = 5 and y2 = -3

∴ The distance between them = I-3 - 5I

∴ The distance between them = I-8I

→ Remember absolute value gives always positive values

∴ The distance between them = 8 units

∴ The distance between the two points is 8 units

Solve the following system of equations using the elimination method. 2x + 4y = 10 –2x + y = –15
pychu [463]

Answer:

(7, - 1 )

Step-by-step explanation:

Given the 2 equations

2x + 4y = 10 → (1)

- 2x + y = - 15 → (2)

Adding the 2 equations term by term eliminates the term in x, that is

5y = - 5 ( divide both sides by 5 )

y = - 1

Substitute y = - 1 into either of the 2 equations and solve for x

Substituting into (1)

2x + 4(- 1) = 10

2x - 4 = 10 ( add 4 to both sides )

2x = 14 ( divide both sides by 2 )

x = 7

Solution is (7, - 1 )

Butoxors [25]

Answer: The answer is (B). paragraph.

Step-by-step explanation:  We are asked the form which a flowchart proof uses to present a logical argument.

A flow chart proof is a map which shows the statements and reasons needed for a proof in a structure that helps to indicate the logical order. The reasons and conclusions are written in the form of paragraphs in the proof.

Therefore, the complete statement is

"A flowchart proof uses a <u>paragraph</u> form to present a logical argument.

Thus, (B) is the correct option.
