Which of the following best describes the set of even integers from 8 to 16

Tresset [83]

Answer:

(8, 10, 12, 14, 16) is the set which describes the set of even integers from 8 to 16

Step-by-step explanation:

To find the set of even integers from 8 to 16 as below :

There are 8,10,12,14,16 even integers in between the numbers 8 and 16

Therefore (8, 10, 12, 14, 16) is the set which describes the set of even integers from 8 to 16

What numbers are zeros of g(x) = x^2 - 2x - 4? take your time if you need to!

Step-by-step explanation:

Hello!

We can solve the quadratic by using the quadratic formula.

Standard form of a quadratic: $ax^2 + bx + c = 0$

Quadratic Formula: $x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}$

Given our Equation: $g(x) = x^2 - 2x - 4$

a = 1
b = -2
c = -4

Plug the values into the equation and solve.

<h3>Solve</h3>

$x = \frac{-b\pm\sqrt{b^2 - 4ac}}{2a}$
$x = \frac{-(-2)\pm\sqrt{(-2)^2 - 4(1)(-4)}}{2(1)}$
$x = \frac{2\pm\sqrt{4 +16}}{2}$
$x = \frac{2\pm\sqrt{20}}{2}$
$x = \frac{2\pm\sqrt{4 * 5}}{2}$
$x = \frac{2\pm(\sqrt4 * \sqrt5)}{2}$
$x = \frac{2\pm2\sqrt5}{2}$
$x = 1 + \sqrt5, x = 1 - \sqrt5$

Solve for x, in terms of y: 2 3 x + 1 5 y = 2

satela [25.4K]

Answer:

(2/3)x - (1/5) y = 10. to solve for x in terms of y: (2/3)x - (1/5) y = 10. (2/3)x = 10 + (1/5)y. x = (10 + (1/5)y)(3/2). x = 15 + 3/10 y. if y = 0; x = 15. to solve for y in terms ...
