Step-by-step explanation:

Hey there!

We can see on this number line that each tick mark represents one because every five marks, there is a difference of five.

Two marks to the left of 0 will be 0 minus 2, so -2.

Three marks to the left of -5 will be -5 minus 3, so -8.

Your answer is -8 and -2.

Hope this helps!

Final answer:

The integers that are being referred to are -8 and -2, which are negative whole numbers located on the left side of zero on a number line.

Explanation:

When plotted on the number line, integers represent whole numbers that can be positive, negative, or zero.

To identify the integers that are plotted, one would look for distinct marks or points on the number line that correspond to whole numbers.

Based on the data, we come to the conclusion that the numbers in question are -8 and -2.

The integers plotted on the number line are -8 and -2. The integer -8 is to the left of -2 on the number line.

These two numbers are examples of negative integers, which are located to the left of zero on a standard number line. The understanding of how to read a number line and identify the placement of integers is a key concept in mathematics, which allows for better comprehension of more complex mathematical ideas such as rational numbers, real numbers, and complex numbers.

Answer:D

Step-by-step explanation:

Answer:

[3x25]+[5x30]

Step-by-step explanation:

6/10 can be simplified but we don't need to worry about it right now. We only need to worry about simplifying 20/100:

20/100 → 10/50 → 5/25 → 1/5

Find common denominators

1/5 → 2/10

6/10

Now, add.

6/10 + 2/10 = 8/10

Therefore, the equation is true.

Best of Luck!

Answer:

6/10+20/100 does not equal 8/10

Step-by-step explanation:

To solve this, all we need to do is find the square root of the numerator and denominator in the fraction

When you see a giant root symbol, picture it like this ....

[tex]\frac{\sqrt{25} }{\sqrt{64} }[/tex]

So, let's solve!

√25 = 5

and

√64 = 8

Now, we have ...

[tex]\frac{5}{8}[/tex]    as our final answer :)

Answer:

B) cos f

Step-by-step explanation:

sin e = DF/EF

cos d = (which side is adjacent i don't even know)/EF

cos f = DF/EF

sin d = opposite (hypotenuse)/hypotenuse, doesn't make sense

sin f = DE/EF

Step-by-step explanation:

Answer:

60 degrees

Step-by-step explanation:

angle y is vertically opposite to angle a, (we can call it.)

angle x is supplementary to the other angle inside the triangle, which we can call angle b.

so, angle a is 60 degrees, as vertically opposite angles are equal

angle b is 60 degrees as supplementary angles = 180

based of the sum of angles in a triangle is 180 theorem;

60+60+unknown= 180

so unknown is 60 degrees

Answer:

D. 13 units

Step-by-step explanation:

The distance between the points (4,-2) and (-1,10) is 13 units.

To find the distance between two points, we can use the distance formula. The distance formula is:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

In this case, the coordinates of the first point are (4, -2) and the coordinates of the second point are (-1, 10). Plugging these values into the distance formula, we get:

d = sqrt((-1 - 4)^2 + (10 - (-2))^2) = sqrt((-5)^2 + (12)^2) = sqrt(25 + 144) = sqrt(169) = 13 units

Therefore, the distance between the points (4, -2) and (-1, 10) is 13 units.

Answer:

30 dollar discount

Step-by-step explanation:

Using the discount parameters given, the final sale price function of the guitar would be f(x) = x - 0.6x - 30 and the discount on initial price of $200 would be $90

Let initial price = x

First discount :

$50 off :

Second discount :

$3 off each $5 of sale price

Final discount :

The Final sale price :

f(x) = x - 0.6x - 30

Given an initial price, x = 200

Discount on price :

Final discount = 0.6x - 30

Discount on price of x = 200 :

0.6(200) - 30

120 - 30 = $90

Therefore, the discount on the price is $90

Step-by-step explanation:

On cutting the circle into more and more slices, its shape will get closer to a rectangle.

A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape.

Given that, a circle is divided into 4 slices. The slices are arranged into the shape.

So, when we will cut the circle into similar manner, the shape we will get closer to will be a rectangle,

When we will calculate the perimeter and the area of the obtained rectangle, it will be equal to the circle.

Hence, on cutting the circle into more and more slices, its shape will get closer to a rectangle.

Final answer:

When a circle is divided into more and more slices and these slices are rearranged, they approximate a circle more closely. While a hexagon may seem like a closer shape due to the angles of its vertices, the ultimate shape remains a circle.

Explanation:

If a student rearranges the slices from a circle cut into more slices, they would get a shape that approximates a circle more closely as the number of slices increases. As each slice becomes thinner, the perimeter of the rearranged shape starts resembling a smooth curve, which is the characteristic of a circle.

Looking at the angles provided, a triangle has 60° angles, a square has 90° angles, a pentagon has 108° angles, and a hexagon has 120° angles. The figures suggest that a hexagon would be a more favorable shape when arranging slices because the angles of a hexagon (120°) are closer to the 360° of a full circle when divided by an increasing number of slices. However, when arranging the slices, the ultimate shape one gets closer to is the circle itself, irrespective of the polygonal shape intermediate stages may suggest.

Answer:

No, is not proportional because it does not go through the origin

Step-by-step explanation:

In order to find whether this is proportional or not you gotta divide y from x

and if the result is the same it means the relationship it is proportional.

Answer:

je ne sais pas le comprendre

Step-by-step explanation:

Answer: 15 + 23 =38

So n + n + 8 = 38

which means n + n = 30

and since the n's are the same, you just cut the 30 in 2 equal pieces. 15 and 15.

So n = 15, n + 8 = 23

15 + 23 = 38   :)

Answer:

x = -2, y= 3

Step-by-step explanation:

y = 4x + 11

y = -2x - 1

Because both equations are equal to y, we can set them equal to each other

4x + 11 = -2x - 1

Add 2x to each side

4x+2x +11 = -2x+2x -1

6x +11 = -1

Subtract 11 from each side

6x+11-11=-1-11

6x = -12

Divide each side by 6

6x/6 = -12/6

x = -2

Now we need to find y

y = -2x-1

y = -2(-2)-1
