x+y
(x + y)(x + y)(x + y)
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 expression (\cos(x + y) \cos x + \cos y) does not simplify to a standard identity. Instead, it can be rewritten using the angle addition formula for cosine: (\cos(x + y) = \cos x \cos y - \sin x \sin y). Therefore, the original expression is not generally true, and its simplification would depend on specific values of (x) and (y).
3xz+3yz+x+y=(x+y)(3z+1)
y=b+x+x^2 This is a quadratic equation. The graph is a parabola. The quadratic equation formula or factoring can be used to solve this.
the answer is: (y-b)/x = m y = mx + b y - b = mx (y-b)/x = m
(x + y)(x + y)(x + y)
The Y-Axis intercept, i.e. when X is zero, Y is b.
The answer to Y x plus 5 Y 6 is Y(x+5Y5).One possible solution to y x plus 5 y 6 is Y(x+5Y5).
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
To graph them, you need to put them into the formula y=mx+b. If x+y=8 subtract x to get y=-x+8. 8 is the y-intercept and your line should be heading downward from left to right.

It is the same. The equation "x + y" is the exact same as "x + y." There is no difference.
x + 7 + y
The expression (\cos(x + y) \cos x + \cos y) does not simplify to a standard identity. Instead, it can be rewritten using the angle addition formula for cosine: (\cos(x + y) = \cos x \cos y - \sin x \sin y). Therefore, the original expression is not generally true, and its simplification would depend on specific values of (x) and (y).
y = x2 + 2mx + n complete the square y + m2 = x2 + 2mx + m2 + n = (x + m)2 + n (x + m)2 = y + m2 - n x + m = √(y + m2 - n) x = -m + √(y + m2 - n)
