What is 8x plus 5x when x8?
The expression "8x plus 5x" simplifies to ( (8 + 5)x ), which is ( 13x ). The reference to "when x8" seems unclear, but if you meant "when x = 8," then substituting gives ( 13(8) = 104 ). Thus, the expression evaluates to 104 when ( x = 8 ).

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.
Is x - 5 the same as 5 - x?
No, ( x - 5 ) is not the same as ( 5 - x ). The expression ( x - 5 ) represents a value that decreases by 5, while ( 5 - x ) represents a value that decreases by ( x ) from 5. In fact, ( 5 - x ) is the negative of ( x - 5 ), meaning they have opposite signs.

What is the value of the expression 4x-2y plus xy when x equals -1and y equals 5?
To find the value of the expression 4x - 2y + xy when x = -1 and y = 5, we first substitute the values of x and y into the expression. This gives us 4(-1) - 2(5) + (-1)(5). Simplifying this further, we get -4 - 10 - 5, which equals -19. Therefore, the value of the expression is -19 when x = -1 and y = 5.
