What is 2x plus 5?
It is 2x + 5. The value of this expression will depend on the value of x: each different value of x will give a different value for the expression.
What is the value of this expression 4n x 2?
4n x 2 = 8n
How do you simplify this 4 over x plus 2 plus 6 over x plus 5?
Assume the expression is:4/(x + 2) + 6/(x + 5)Simplify this expression by combining the expressions altogether. Let's go step by step.Step 1: Determine the LCD of the expression.The LCD of the expression is (x + 2)(x + 5). Multiply the top and bottom of each fractional expression by whatever factor the denominator is missing!4/(x + 2) * (x + 5)/(x + 5) + 6/(x + 5) * (x + 2)/(x + 2)Step 2: Combine the expression and simplify.(4(x + 5) + 6(x + 2))/((x + 2)(x + 5))= (4x + 20 + 6x + 12)/((x + 2)(x + 5))= (10x + 32)/((x + 2)(x + 5))
The vertex of this parabola is at 5 5 When the x-value is 6 the y-value is -1 What is the coefficient of the squared expression in the parabola's equation?
The vertex of this parabola is at 5 5 When the x-value is 6 the y-value is -1. The coefficient of the squared expression in the parabola's equation is -6.
What is the value of the expression x-y squared when x equals 7 and y equals negative 2?
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.
Whats x 3 -2?
5
Evaluate 3x plus 5when x 2 what is the value of the expression is?
When x = 2, 3x + 5 = 11.
What is 2x plus 5?
It is 2x + 5. The value of this expression will depend on the value of x: each different value of x will give a different value for the expression.
The vertex of this parabola is at -5 -2 When the x-value is -4 the y-value is 2 What is the coefficient of the squared expression in the parabola's equation?
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
How does the value of the expression x plus 5 change each time you increase the value of x by 1?
each time you add 1 to x the value goes up by one for example if x=2 then 5+2=7 but if you add 1 to x and x=3 then 5+3=8
What is the value of the expression x-8 when x 5?
-3
For which value of x is the expression 6-xx 2?
4
What ia the value of the expression 13-2x when the value of x is 4?
Just substitute 4 in for X. 13 - 2(4) 13 - 8 = 5 ===
What values of x make the expression 5-xx(x-2) undefined?
Which of these values of x make the expression undefined? 5-x/x(x-2)
What is the expression (x plus 5)(x-7)?
The expression (x+5)(x-7) = x^2 -2x -35
What is the value of the expression 4x3 when x 2?
When x = 2, 4x3 = 32
What is the value of this expression 4n x 2?
4n x 2 = 8n
