-2
To determine the value expression when ( x = -2 ), you need to substitute -2 into the given expression. For example, if the expression is ( 2x + 3 ), substituting -2 gives ( 2(-2) + 3 = -4 + 3 = -1 ). The specific value will depend on the expression you have; please provide that for a more accurate answer.
Just substitute 4 in for X. 13 - 2(4) 13 - 8 = 5 ===
It is: (-4*-2)3 = 512
Substituting a given value for each variable in an algebraic expression involves replacing the variables with specific numbers to evaluate the expression. For example, in the expression (2x + 3y), if (x = 2) and (y = 4), you would replace (x) with 2 and (y) with 4, resulting in (2(2) + 3(4) = 4 + 12 = 16). This process allows you to compute a numerical result from the expression based on the values assigned to its variables.

If you mean: x^2+15-3x then its value is 19 when x equals 4
Just substitute 4 in for X. 13 - 2(4) 13 - 8 = 5 ===
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: (-4*-2)3 = 512
If the expression is (x - y)2, the solution is (7 - -2)2 = (7+2)2 = 92 = 81. If the expression is x - y2, the solution is 7 - (-2)2 = 7 - 4 = 3.
It is an algebraic expression that can be simplified depending on the plus or minus value of 4
4n x 2 = 8n
When x = 2, 4x3 = 32
Since there is no expression given, there is no sensible answer.
