2xy=-8

You can find a value of x and a value for y that would make that true, so YES it is a function.
Example:
2(2)(-2) = -8

What is the value of X plz help

Tema [17]

Answer:

x = 16

Step-by-step explanation:

(5x + 12)° + (6x - 8)° = 180°

(5x + 12 + 6x - 8)° = 180°

(11x + 4)° = 180°

11x + 4 = 180

11x = 180- 4

11x = 176

x = 176/11

x = 16

Go step by step to reduce the radical of the equation given. (Figure the step for the box)

Rama09 [41]

$\sqrt{32} ~~ \begin{cases} 32=2\cdot 2\cdot 2\cdot 2\cdot 2\\ \qquad 2^4\cdot 2\\ \qquad 2^{(2)(2)}\cdot 2\\ \qquad (2^2)^2\cdot 2 \end{cases}\implies \sqrt{(2^2)^2\cdot 2}\implies 2^2\sqrt{2}\implies 4\sqrt{2}$

Write an equation the nth term of the arithmetic sequence -5,0,5,10 then find a10

Monica [59]

Step-by-step explanation:

a(n) = a +(n-1)d

a=-5

d=5

a(n) = -5 +(n-1)5

=-5+5n-5

=5n-10

a(50) = -5 +(50-1)5

= 240
