The equation will be

\\ \sf\longmapsto \sqrt{x^2+y^2}=7

\\ \sf\longmapsto x^2+y^2=7

  • If y be 0

\\ \sf\longmapsto x^2+0=7^2

\\ \sf\longmapsto x^2=49

\\ \sf\longmapsto x=\sqrt{49}

\\ \sf\longmapsto x=\pm 7

Now the points are

  • (7,0)
  • (-7,0)

Answer:

  • (-7, 0) and (7, 0)

Step-by-step explanation:

<u>All the points that are 7 units from the origin are on the circle:</u>

  • x² + y² = 7²

<u>The maximum and minimum values of x obtained when y = 0:</u>

  • x² = 7²
  • √x² = √7²
  • x = ± 7

So

  • min x = -7 and
  • max x = 7

<u>The points are:</u>

  • (-7, 0) and (7, 0)

Diano4ka-milaya [45]

140 is the solution of the inequality

Step-by-step explanation:

The inequalities are used just like equations.

Given

Total amount to be raised = $950

Price of one ticket = $2.50

The inequality that represents the situation is:

2.50x≥950

Dividing both sides by 2.50

\frac{2.50x}{2.50} \geq \frac{950}{2.50}\\x\geq 140

140 is the solution of the inequality

When you subtract and add what is in the parentheses you would get -15 so I’m guessing he didn’t go from left to right when working inside the parentheses but when you solve the whole problem out you would get the answer: -41.25 If I missed something or you need me to show the work just let me know but I hope this helps !
