The theorem that justifies this statement ∠4≅∠6 is; Alternate Interior Angles.

What are Alternate Interior angles?

When two parallel lines are crossed by a transversal line, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These alternate interior angles are always equal.

From the given diagram, we see that ∠4 and ∠6 fall into the category of alternate interior angles.

You need to write an essay that has at least 700 words. You have written 300 words so far. Write an inequality that represents the number of words w that you have left to write.

Answers

Answer:

300 + w ≤ 700

Step-by-step explanation:

It would not be 300 + w = 700 because you have to write at least 700 words, so 300 + w must be equal to or greater than 700, and the equal to or greater than sign is ≤

(x + y)² = 121

Step-by-step explanation:

Using the identity

(x + y)² - (x - y)² = 4xy , then

(x + y)² - 5² = 4(24) , that is

(x + y)² - 25 = 96 ( add 25 to both sides )

(x + y)² = 121

A line passes through the points (−8,−7) and (−4,−4). What is the equation of the line in Slope-Intercept Form? (A y=43x−1) (B y=34x−1) (C y=43x+1) (D y=34x+1)

Answers

Answer:

y=43x−1

Step-by-step explanation:

The equation of the line in Slope-Intercept Form is B: y = (3/4)x − 1.

What is the meaning of Slope-Intercept Form?The slope intercept form of such a straight line is among the most common ways to represent a line's equation. When given the slope of a straight line and the y-intercept, the slope intercept equation can be utilized to find the equation of a line.

For the given question.

The  line passes through the points-

(x1, y1) =  (−8,−7)  

(x2, y2) = (−4,−4).

Find the slope using formula;

slope = m = (y2 - y1)/(x2 - x1)

m = (-4 + 7)/(-4 + 8)

m = 3/4

The equation of the line in slope intercept form is found by;

y - y1 = m(x - x1)

y + 7 = (3/4)(x + 8)

y = (3/4)x - 1

Thus, the equation of the line in Slope-Intercept Form is B: y = (3/4)x − 1.

He could say that he is -15 feet as seen from the sea level

The given statement can be represented in an integer as -15.

Given that, Joe lives in a city that is 15 feet below sea level.

We need to find how could he represent his elevation as an integer

How will you represent a sea level as an integer?

Whole numbers less than zero are called negative integers (-). These numbers are to the left of zero on the number line. Zero is neutral. It is neither positive nor negative.

Now, 15 feet below sea level can be represented as -15.

Therefore, the given statement can be represented in an integer as -15.

A father's age is three times the sum
of the ages of his two children.After 5
years his age will be two times the sum
of their ages.Find the present age of the
father​

Answers

Let the age of father be x years and sum of the ages of his children by y years.
After 5 years,
Father's age = (x + 5) years
Sum of ages of his children = (y + 10) years
From the given information, we have:
x = 3y ...(1)
and x + 5 = 2(y + 10)
x - 2y = 15 ...(2)
From (1) and (2), we have,
3y - 2y = 15 y = 15
x = 3y = 45
Father's age = 45 years
