4X - 1 = 9
Is an equation.
4X - 1 = 9
4X = 10
X = 5/2
=====
9 + (9 / 9) + (9 / 9) + (9 / 9) = 12
The answer is -369.
-4 (-9 +5 = -4)
The expression "-9 squared" means to multiply -9 by itself. When you calculate this, you get ((-9) \times (-9) = 81). Therefore, -9 squared equals 81.
If you meant 2x+3=4x²x=(1±√(13))/4x1≈1.151387818866x2≈-0.651387818866
explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
9 + (9 / 9) + (9 / 9) + (9 / 9) = 12
The answer is -369.
It is 9
-4 (-9 +5 = -4)
It is an algebraic expression involving x. Of do you mean 'what is x if 2x - 9 equals 9?' 2x - 9 = 9 ⇒ 2x - 9 + 9 = 9 + 9 ⇒ 2x = 18 ⇒ 2x ÷ 2 = 18 ÷ 2 ⇒ x = 9
(60 - 2*27) + 9/3 = 9
(3 * 3)(2 * 5) (9)(10) 90
5X - 2Y X = 9 Y = 4 5(9) - 2(4) 45 - 8 37 is the value

Umm Well it doesn't have an equals sign in it so its not an equation its just an expression
No because it contains an equal sign in it.
