The right answer is C. The set of all points in a plane that are a certain distance from a single point


The certain distance is called the <em>radius</em> and the single point is called the <em>center. </em>In this way, all points are a certain or, in other words, the same distance from the center. So, for the Standard Form of the Equation of a Circle we have that:


The \ point \ (x,y) \ lies \ on \ the \ circle \ of \\ \mathbf{radius} \ r \ and \ \mathbf{center} \ (h,k) \ if \ and \ only \ if :\\ \\ (x-h)^2+(y-k)^2=r^2

How can you solve a system of linear equations? How can you check your solution?
natali 33 [55]
<span>After you solve a system of linear equations, you will get an ordered pair (x,y). Replace x with whatever number you obtained for x, and replace y with whatever number you obtained for y. If both your equations are true upon simplifying, you know it is correct.</span>

Hey guys, I need help with these Scale factor problems! problems are linked in a screenshot below:
AVprozaik [17]

Answer:

  1. A → B: 1/3
  2. correct
  3. A → B: 2/5

Step-by-step explanation:

It is clear from your answer to the second part that you know the A→B scale factor is the reciprocal of the B→A scale factor. Use that fact for the other two parts of the question.

  1. A → B = 1/3; B → A = 3
  2. A → B = 2; B → A = 1/2
  3. A → B = 2/5; B → A = 5/2

__

It is convenient to find a unit length (or the smallest length) on the smaller figure, then see how much that is multiplied by to get the larger figure.

  1. B : A = 1 : 3
  2. A : B = 1 : 2
  3. B : A = 2 : 5

Once you have these ratios, you need to determine what the notation A→B is supposed to mean. Here, we presume it means B/A.

Simplify and solve for the unknown. Use order of operations as needed. Check your work.
antiseptic1488 [7]

Answer:

5

Step-by-step explanation:

Given: 5^3– 10^2 = X(8 – 2) + 2X – 3X

Solving the equation to find the value of x.

⇒ 5^{3} -10^{2} = x(8-2)+2x-3x

Using the distributive property of multiplication, multiplying x with 8 and -2

⇒125-100= 8x-2x+2x-3x

cancelling out -2x and 2x

⇒ 25= 8x-3x

⇒ 25= 5x

Multiplying both side by 5

⇒ x= \frac{25}{5}

∴ x= 5

Hence, the value of unknown is 5.
