can someone explain to me how to find angles on graphing and if there is 2x+50 what it means... thanks :)

Let f(x) = 2x + 50

The angle to this equation would be the coefficient "a''

Look:

f(x) = ax + b

Then,

To this question, a = 2

Always, a = Tg(angle)

That would be the slope of the line.

Tg(angle) = a

Tg(angle) = 2

Apply arctg on both the sides

ArcTg(Tg(angle) ) = Arctg(2)

Arctg(tg ) , They cancel

Angle = Arctg(2)

Calculate the Arctg(2) on the calculator

Angle = 63,43°

Which of these graphs represents the inequality x > 5?

nadezda [96]

Answer:

A is correct.

x>5 means all numbers greater than BUT not equal to 5.

The open circle means "not equal".

So, A is correct.

Hope this helps!

Apply the distributive property and the greatest common factor to write an equivalent expression.

Here, Your Original expression is 60x - 24.

Take 12 as common, which is GCD of 24 & 60,

Therefore, It would be:

60x - 24
= 12 * 5x - 12 * 2
= 12 (5x - 2)

In short, your Answer would be 12(5x - 2)

Hope this helps!
