brainliest if right easy question

Answers

Answer:

349,800.0 because the number 10 to the 4th power has four zeros when it is written without an exponent.

Step-by-step explanation:

34.98 x 10^4 = 349,800.0 = 349,800

34.98×10⁴ = 349,800.0 because the number 10 to the 4th power has four zeros when it is written without an exponent.

Here, we have,

given that,

the term is: 34.98 x 10⁴

now, we have to find the result of multiplication without an exponent.

so, we get,

34.98 x 10⁴

=34.98 x 10000

= 349,800.0

= 349,800

Hence, 34.98×10⁴ = 349,800.0 because the number 10 to the 4th power has four zeros when it is written without an exponent.

which graph models the solution of the Inequality -6 ≤ -3x

Answers

Answer- B

First make x the subject which would be -6/-3 ≤ x
Which is 2 ≤x and that is represented in B

We know that graph (B) models the solution of the given inequality -6 ≤ -3x.

What are graphs?Drawing the curve that represents a function on a coordinate plane is known as graphing a function. Every point on the curve will satisfy the function equation if the curve (or graph) represents the function.Line graphs, bar graphs, pie charts, scatter plots, and histograms are examples of common graph types. Graphs are a fantastic tool for displaying statistics and visualizing data. To depict numerical data that is unrelated to one another, a bar graph or chart may be utilized.

So, in the given inequality:

-6 ≤ -3x

We know that:

Make x subject: -6/-3 ≤ xWhich is 2 ≤ x, represented in a graph (B).

Therefore, we know that graph (B) models the solution of the given inequality -6 ≤ -3x.

What is angle Bi-sector?

In geometry, an angle bisector is a line that divides an angle into two equal angles. The term "bisector" refers to a device that divides an item or a form into two equal halves. An angle bisector is a ray that divides an angle into two identical segments of the same length.

Given, A triangle in that there is an angle bisector AB.

Since,

Median:

A median of a triangle is a line segment that joins a vertex to the mid-point of the side that is opposite to that vertex.

In our case, it is not specified if AB bisects the opposite line

Altitude:

The altitude of a triangle is the perpendicular drawn from the vertex of the triangle to the opposite side. Also, known as the height of the triangle, the altitude makes a right-angle triangle with the base.

In our case, it is not specified if AB makes a Right triangle or not.

Therefore, Line Ab is neither a Median nor an Altitude.

Answers

Answer: 6 is the slope and 4 is the y-intercept.

Step-by-step explanation:

Based on the question, I feel this is the best way to answer your question.  I'm assuming you are in a basic graphing class.

The best, most useful thing for you right now would be to learn slope-intercept form, y = mx + b, where m and b are constants.

Simply add 6x to both sides to get into this form

y = 6x + 4.

In slope-intercept form, m is the slope, and b is the y-intercept.  Thus, 6 is the slope and 4 is the y-intercept.

What is Coordinate Geometry?

One of the most intriguing ideas in mathematics is called coordinate geometry. By using graphs with curves and lines, coordinate geometry (also known as the analytic geometry) explains how geometry and algebra are related.

As per the given data:

Coordinates of point M = (-10, -7)

Rotation to be given = 180° (counter - clockwise)

For drawing the image of point M (-10, -7):

Step 1: Create a line connecting the origin to the point M (-10, -7) and extending across the third and first quadrants.

Step 2: Modify the x and y coordinates signs to reflect the 180° rotation, then mark the point in the first quadrant.

The image of the point M is M' = (10, 7) as shown in the graph below.

Hence, the image of the point M is M' = (10, 7).

Step-by-step explanation:

if you look at the graph, if there is a closed circle, that means x can be equal to whatever number the circle is on. if the circle is open, that means you don't include that number, which is in this case two. a closed circle means that x can be equal to 2. since the arrow is going from 2 to the left, x can be anything from two to any real numbers to the left. therefore, since to the left goes to numbers smaller than 2, x can either be equal to or less than two.

The solution of the inequality 3/4 x - 2/3 ≤ 5/6 which is graphed on given number line is x ≤ 2.

Here inequality is given as;

3/4 x - 2/3 ≤ 5/6

What is inequality?

A statement of an order relationship; less than, greater than, greater than or equal to, less than or equal to, between two algebraic expression is known as inequality.

Now,

3/4 x - 2/3 ≤ 5/6

3/4 x - 2/3 + 2/3 ≤ 5/6 + 2/3

3/4 x ≤ 7/3

Now multiply both side by 4/3;

[tex]\frac{3}{4} x *\frac{4}{3} \leq \frac{7}{3} *\frac{4}{3} \\x\leq \frac{28}{9} \\x\leq 3.11\\[/tex]

Answers

Answer:

See answer below

Step-by-step explanation:

In this case, this is just sum, substraction and divisions using the properties or the signus. This is just basic operations using the negative and positive numbers.

To do this easily you just have to remember the following:

1. Numbers with same sign, must be summed and put the sign that have either number.

2. Numbers with different sign, must be substracted and then put the sign of the highest number.

3. If you have a multiplication or division:

- Same signs multiplied or dividied (Either positive or negative), result always positive.

- Different signs multiplied or dividied (positive and negative), result always negative.

Following this simple rules, you'll be able to solve almost any exercise of this.

Now, according to the rules above, let's solve the exercises:

A. (-13) + (-7)

In this case, you have two negative numbers, and one positive sign between them. Apply the 3rd rule. The negative sign remains and then:

-13 - 7

Now 1st rule applied, sum the numbers and let the same sign:

-13 - 7 = -20.

B. (-15) - (-15) = 0.

Applying 3rd rule and then 2nd rule, we have a subtration of -15 + 15.

C. (2) * (-13) = -26

Applying the 3rd rule, we have positive and negative, result always negative.

D. (-44) / 11 = -4

3rd rule applied.

E. (-3) + (-5) + 8 + 25 = 31

Applied 3rd and 1st rule.

I don't understand the f, but you can use the rules here and get the final answer of that one.
