If you mean 8y^2 +14y = 15 then the value of y is -5/2 or 3/4
If you mean 8y^2 +14y = 15 then the value of y is -5/2 or 3/4
The answer depends on the value of y. For example, when y = 0, 8y2 + 6y - 2 = -2 when y = 1, it is 12
If y = 10, then -8y2 = -8(10)2 = -800.
y += x means the value y+x is first calculated, and the resulting value is then assigned to y. It is equivalent to y = y+x
The answer depends on the value of y.
Times the numbers together, 4 x 2 = 8 Times the independent variables, y x y = y2 answer = 8y2
Y = 2
It is 13 + y, whose value cannot be determined without the value of y.
x = 14
The value of Y in the equation 4-y plus 6 = 45 is -35.
That depends on the value of y.
The value of x + y is indeterminate. You need the values of both x and y to determine x + y.
(1/x) + (1/y) + (1/z) is a minimum value when x=y=z=10. Symmetry gives either maximum or minimum value.
