While “digital” commonly refers to electronics in general, the scientific definition of digital is much different. “Digital” in information science refers to the finite, discontinuous phenomenon (e.g., on or off states in a light bulb) as opposed to infinitely varying, continuous analog phenomenon (e.g., the brightness of daylight). It can also refer to representing data in figures as opposed to data represented in pictorial form.

What is the value of X?

andrezito [222]

Solution:

Note that:

3x + 50 = 6x - 10 (Vertically opposite angles)

Simplify the equation to find x.

Add 10 both sides.

3x + 50 = 6x - 10
=> 3x + 50 + 10 = 6x - 10 + 10
=> 3x + 60 = 6x

Subtract 3x both sides.

3x + 60 = 6x
=> 3x - 3x + 60 = 6x - 3x
=> 60 = 3x

Divide 3 both sides.

60 = 3x
=> 60/3 = 3x/3
=> x = 20

Does anyone get this?

stepladder [879]

Answer: B

Step-by-step explanation:

In the systems of equation it already gives you the solution for x which is -2 so all you have to do is substitute -2 into the first equation and solve for y.

y= 2/3x + 3

x= -2

Substitute x for -2

y = $\frac{2}{3}* \frac{-2}1} + 3$

y= $\frac{-4}{3}$ + $\frac{3}{1}$

y = $\frac{5}{3}$

so now you have the solution like this $(-2,\frac{5}{3})$
