If you mean: x^2+15-3x then its value is 19 when x equals 4
The value is 1 if (x, y) = (4, 3) and 0 otherwise.
If x stays the same the expression stays the same. Since the expression involves negative x, the value of the expression decreases as x increases.
5X - 2Y X = 9 Y = 4 5(9) - 2(4) 45 - 8 37 is the value
The vertex of this parabola is at -5 -2 When the x-value is -4 the y-value is 2. The coefficient of the squared expression in the parabola's equation is 4. y = a(x - h)2 + k; (h, k) = (-5, -2); (x, y) = (-4, 2) 2 = a[-4 -(-5)]2 - 2, add 2 to both sides 4 = a(-4 +5)2 4 = a(1)2 4 = a
It is an algebraic expression that can be simplified depending on the plus or minus value of 4

If you mean: x^2+15-3x then its value is 19 when x equals 4
-4 (-9 +5 = -4)
The value is 1 if (x, y) = (4, 3) and 0 otherwise.
Just substitute 4 in for X. 13 - 2(4) 13 - 8 = 5 ===
The value of x is the unknown variable and the given expression can be simplified to: 4x-15
Say you have an algebraic expression y = 3x +4 For a given value of x = 5 substitute that number in place of x in the expression, so in this case y = 3(5) + 4 = 19
X2 Is an algebraic expression. X2 = 4 Is an equation that can be solved for X. The variable, X, in this case, has two values. In the expression any value can be substituted for X.
That depends on the value of x in the given expression
