Answer:

  • 71 and 19

Step-by-step explanation:

<u>Numbers are x and y, equations below:</u>

  • x + y = 90
  • x = 3y + 14

<u>Substitute x in the first equation:</u>

  • 3y + 14 + y = 90

<u>Solve for y:</u>

  • 4y + 14 = 90
  • 4y = 76
  • y = 19

<u>Find x:</u>

  • x = 90 - 19 = 71

valina [46]

The equation representing the value of the collection after 7 years is  value of collection = 430 + (0.04 * 430 )* 7 or value of collection = $550.4

<h3>What is an Equation ?</h3>

An equation is a mathematical statement , where the algebraic expression is equated to another algebraic expression.

It is given that

Ella has a collection of vintage action figures that is worth $430.

collection

appreciates at a rate of 4% per year

equation representing the value of the collection after 7 years is

value of collection = 430 + (0.04 * 430 )* t

value of collection = 430 + (0.04 * 430 )* 7

= $550.4

Therefore the equation representing the value of the collection after 7 years is  value of collection = 430 + (0.04 * 430 )* 7 or value of collection = $550.4

Determine and state the coordinates of the center and length of the radius of a circle whose equation is
padilas [110]
First, rewrite the equation in standard form.
The center-radius form of the circle equation<span> is in the format:
(x – h)^</span>2<span> + (y – k)^</span>2<span> = r^</span>2
<span>with the center being at the </span>point<span> (h, k) and the radius being "r".
</span>
(x-3)^2 + (y+4)^2 = 81

From here, you can determine the center and radius. The center is at (3,-4) and the radius is 9.
