Answer: II Only

Step-by-step explanation:

Let's see.

The given inequality is -2<=-8-x

Therefore, we can add 8 to both sides and get

6<=-x

Now we need to multiply -1 to both sides to get

x<=-6, which means that x is less than or equal to -6.

Now the only choice that satisfies this inequality is -6.

So II only is the answer.

As a result, the solution is shaped like a circle ( -5 , 7 ). The second half of the text has a 6 mm diameter. Three and four are FALSE. There are ten miles between points A and B.

The construction of a circle is the outcome of following a thinking object in a plane and keeping a fixed distance from a particular location. A Greek word kirkos, which means hoop or ring, is the source of the English word circle.

Here,

Typically, a circle's equation is,

( x - h )² + ( y - k ) ( y - k )

x² = r²

( y - k ) ( y - k ) = r²

6² = r²

where the radius of the ring is and the center's coordinates are (h, k).

Part 1.

We arrive to using the formula for the common circle.

The circumference of a circle's coordinate is ( -5 , 7 )

As a result, the second choice is the best.

Part 2.

We arrive to using the formula for the common circle.

The circle's diameter is six.

The initial choice is therefore the best.

Part 3.

We arrive to using the equation again for common circle.

Circle circumference coordinate: ( 2 , 3 )

False as a result.

The axis coordinates of the circle are: ( 2 , 3 )

False, then.

Answer:

Untuk mencari nilai x dari persamaan 4x+7x+141+85+x+27=360, pertama-tama kita harus menyederhanakan persamaan tersebut dengan menambahkan semua x yang ada di sisi kiri persamaan.

4x+7x+x = 12x

Selanjutnya, kita harus mengurangi semua bilangan yang ada di sisi kiri persamaan dari kedua sisi persamaan:

360 = 12x + 141 + 85 + 27

Setelah itu, kita harus mengurangi semua bilangan yang ada di sisi kanan persamaan dari kedua sisi persamaan:

360 - 253 = 12x

107 = 12x

Akhirnya, kita harus membagi 107 dengan 12 untuk mencari nilai x:

x = 8.9167

Jadi, nilai x dari persamaan tersebut adalah 8.9167.

It's worth noting that some steps are not needed to be done and the equation can be simplified by doing some operations at once like : (4x+7x+x+141+85+27=360) => (12x+253=360) => (12x=107) => (x=8.9167)

The break-even point is 1100 products sold. This means that if the store can sell 1100 products, it will be able to cover its costs and make a profit.

What is average ?

The average is a measure of central tendency that is calculated by adding a set of values together and dividing the sum by the number of values. It is also known as the arithmetic mean. It is a way to represent a typical value of a dataset.

The break-even point is the point at which the cost of the products equals the revenue from the sales of the products. To find the break-even point, we need to set the cost function (C(x) = 550 + 3.00x) equal to the revenue function (R(x) = 5.50x) and solve for x.

C(x) = 550 + 3.00x = R(x) = 5.50x

3.00x = 5.50x - 550

0.50x = 550

x = 1100

So the break-even point is 1100 products sold. This means that if the store can sell 1100 products, it will be able to cover its costs and make a profit.

Answer: 4xy²(5-y)

Step-by-step explanation:

To factorize, we must take out common multiples in both parts of the equation. Think of 20xy² and -4xy³ as two completely separate parts. Now, we need to see which parts of the equation are found in both. For instance, 4 can go into both, an x can go into both, and y² can go into both. Now, we simply factor.

Bring the similarities out to the front: 4xy²()

Now, use division to find what would be inside the parenthesis: 5 - y

Now, combine these two parts: 4xy²(5-y)

To check your work, you can simply multiply the outside of the parenthesis by the inside, and you should get the same as what you started with. Hope this helps!

The manager of a garden shop wants to make a mixture that contains 74% rye grass. The weight of the 60% mixture used in this composition is 30 lb.

Percentage is used to denote a fraction of a hundred.

Suppose q represents the weight of the mix that contains 60% rye grass, then the weight of rye grass in this mix is:

w1 = 60% q = 0.6 q

Mix 2: 70 lb grass seed that contains 80% rye grass. The weight of rye grass in the second mix is:

w1 = 80% x 70 = 56 lb

The final mixture has 74% rye grass. Total weight of rye grass in the final mixture:

weight of rye grass = w1 + w2

                                = 0.6 q + 56

Total weight of the final mixture = (q + 70) lb

74% = 0.74 = (0.6 q + 56) / (q + 70)

0.6 q + 56 = 0.74 (q + 70)

0.74 q - 0.6 q = 56 - 0.74 x 70

0.14 q = 4.2

q = 4.2/0.14 = 30

Hence, the weight of 60% mixture is 30 lb.

Answer:The graph of x = -4 is a vertical line located 4 units to the left of the y-axis.

The domain of x = -4 is the set of all real numbers, since any real number can be plugged into x = -4 and the equation will be true. This is because x = -4 is a vertical line and not a function, it cuts the y-axis at one point, so it doesn't matter what value you put on x it will always be -4.

The range of x = -4 is a single point on the y-axis, y = -4.

Answer:

  see attached for a graph

  a. BA≅BC (the compass told me so)

  c. AD≅CD

Step-by-step explanation:

You want a graph of ∆ABC, with A(4, 7), B(0, 0), and C(8, 1). You want to identify the congruent sides, construct an angle bisector, and comment on how it divides the opposite side.

The graph of the points, and the construction of the angle bisector are shown in the attachment.

Since you have your compass available for construction, you can use set it to the measure of one side and compare that to the other two sides. It does not take long to identify AB ≅ BC. (A compass setting shows they are the same length.)

As you know, an angle bisector is constructed by first identifying two points on the sides of the angle that are the same distance from the vertex of the angle. Then two intersecting arcs are drawn with the same radius using those points as their centers. The vertex and the intersection of the arcs defines the ray that is the angle bisector. This is shown in the attachment.

You can count grid squares (or use the compass) to determine that AD and CD are the same length: D is the midpoint of AC.

This reinforces your knowledge that the angle bisector of the a.pex angle of an isosceles triangle is also an altitude and a median.

When you divide a number by 1/2, it is the same as multiplying the number by 2. Therefore, the result of the division is two times the original number.

Let's say we have a number, X.

When you divide X by 1/2, you can rewrite the equation as:

X ÷ 1/2 = X × 2

Thus, the result of the division is two times the original number, X.

Let's say we have a number, X. When you divide X by 1/2, you are essentially multiplying X by 2. This means that the result of the division is two times the original number. In other words, if you divide X by 1/2, the answer will be 2X. To put it another way, if you take any number, X, and divide it by 1/2, the result will be two times the original number. This is because 1/2 is the same as multiplying the number by 2. For example, if you divide 10 by 1/2, the result will be 20, since 10 multiplied by 2 is 20. Similarly, if you divide 25 by 1/2, the result will be 50, since 25 multiplied by 2 is 50. In conclusion, when you divide any number, X, by 1/2, the result will always be two times the original number.

The answer is: m∠E < m∠F < m∠D

The angle of a triangle can be found given its 3 sides using the cosine rule.

The formula is: cos(C) = (a² + b² -c²) / 2ab  

where c is the length of the side opposite angle C, a and b are the lengths of the other two sides, and cos(C) is the cosine of angle C.

DE = f = 69 miles, EF = d = 70 miles and DF = e = 43 miles

cos (F) = (d² + e² -f²) / 2de  

cos (F) = (70² + 43² -69²) / (2*70*43)

cos (F) = 71/215

F = cos⁻¹(71/215)

F = 70.72°

cos (E) = (d² + f² -e²) / 2df

cos (E) = (70² + 69² -43²) / (2*70*69)

The largest angle in wxyz is z = 8w + 3.

In a convex quadrilateral wxyz, the degree measure of angle x is four times that of angle w. This means that the measure of angle x is four times the measure of angle w. The measure of angle y is double that of angle x. This means that the measure of angle y is twice the measure of angle x, or eight times the measure of angle w. Lastly, the measure of angle z is 3 degrees larger than that of angle y. This means that the measure of angle z is eight times the measure of angle w plus three degrees.
