Without commas ... it could be:
3 - 4x = -89 or
4x - 3 = -89 or
(3-4) x = -89 or
(4-3) x = -89...

Answer:

In a box and whisker plot, there is a rectangle (box) with a line in the middle of it. The middle is the mean. The interquartile values are the ends of the rectangle (the lower one -- 25% -- to the left and the higher one -- 75% -- to the right).

Answer: OPTION B.

Step-by-step explanation:

Given the following System of equations:

$\left \{ {{3x-5y=19} \atop {x+y=1}} \right.$

You can use the Elimination Method to solve it. The steps are:

1. You can mutliply the second equation by -3.

2. Then you must add the equations.

3. Solve for the variable "y".

Then:

$\left \{ {{3x-5y=19} \atop {-3x-3y=-3}} \right.\\.....................\\-8y=16\\\\y=\frac{16}{-8}\\\\y=-2$

4. Now that you know the value of the variable "y", you must substitute it into any original equation.

5. The final step is to solve for "x" in order to find its value.

Then:

$x+(-2)=1\\\\x=1+2\\\\x=3$

Therefore, the solution is:

$(3,-2)$
