The value of the equation 3ab - 9ab + 7ab is \boxed{ab}.

Further explanation:

There are two properties.

1. The property of addition or property of sum.

2. The property of subtraction.

3. The property of division.

4. The property of multiplication.

Given:

The equation is 3ab - 9ab + 7ab.

Explanation:

Consider the equation S = 3ab - 9ab + 7ab.

The equation contains the two variables that are “a” and “b”.

In the equation we have two operations one is addition and another is subtraction.

Solve the above equation to obtain the value of the equation.

First add 3ab and 7ab.

\begin{aligned}X&=3ab+7ab\\&=10ab\\\end{aligned}

Now subtract 9ab from 10ab.

\begin{aligned}S&=10ab-9ab\\&=1ab\\&=ab\\\end{aligned}

The value of S is ab.

Hence, the value of the equation 3ab - 9ab + 7ab is \boxed{ab}.

3x+2y=6 and y=1/3x-11 perpendicular or parallel
IgorLugansk [536]

Answer: To determine if two lines are parallel or perpendicular, you have to look at the slopes. For the line y=kx+b, k is the slope.

For two lines  y=k1x+b1 and y=k2X+b2 ,When K1=K2, two lines are parallel; when K1=-1/k2, two lines are perpendicular. It doesn't matter whatever b1, b2 are. Hence to save time, you only need to calculate  k1 and k2.

To calculate the slope k of any line, you have to change the equation to y=kx+b

For -y=3x-2, k=3/(-1)=-3 (you divide -1 on each side of =, but you don't need to calculate -2/(-1))

For -6X+2y=6, K=6/2=3 (you first move the -6x to right side, it becomes 6x, then divide by 2)

Now you can get the answer: The two lines neither parallel nor perpendicular.
