The graph is showing the equation of circle x²+y²=4

<h3>What is a circle?</h3>

A circle is a two-dimensional geometry on the plane having a centre point and the circular line is drawn equidistant from the centre point.

The given graph in the question represents the equation of the circle cutting the points on the x-axis and y-axis at 4 which is the radius of the circle.

The equation will be as follows:-

x²+y²=4

Hence the graph is showing the equation of circle x²+y²=4

HELP I NEED HELP SETTING THIS UP

Answers:

The starting equation is (x+5)/3 = 7 which can be written as \frac{x+5}{3} = 7

The solution to this equation is x = 16

========================================================

Explanation:

Let x be a placeholder for some number. If we start off with some number and add on 5, then we go from x to x+5. The next thing we do is divide all of "x+5" all over 3 to get (x+5)/3 which can be written as \frac{x+5}{3}. I'll use the first style of notation.

Set the expression (x+5)/3 equal to 7 and that leads us to the equation:

(x+5)/3 = 7

so this is the first part of the answer. Now onto the second part which is solving for x. We want to get x all by itself on its own side.

To do this, we follow the order of operations PEMDAS in reverse. So we undo division first by multiplying both sides by 3. Then we undo the addition of 5 by subtracting 5 from both sides

(x+5)/3 = 7

3*(x+5)/3 = 3*7 ...... multiply both sides by 3

x+5 = 21

x+5 - 5 = 21 - 5 ..... subtract 5 from both sides

x = 16

So the unknown mystery number is 16. As a check, note how adding 5 to 16 gets us 16+5 = 21, which if we divide by 3 we end up with 21/3 = 7 which is what we want. So the answer is confirmed.
