3.1 # 4). (5,1) is a solution to the equation 2x - 3y = 7. What does this mean? **Weegy:** FOIL (First Outside Inside Last)
= 2x(2x) + 2x(-3y) + (-3y)(2x) + (-3y)(-3y)
= 4x^2 + (-6xy) + (-6xy) + (9y^2)
= 4x^2 - 12xy + 9y^2

It means that if we substitute solution (5,1) to the equation 2x - 3y = 7, it would result to a true statement.

2(5) - 3(1) = 7

10 - 3 = 7

7=7, therefore it is correct.

2(5) - 3(1) = 7

10 - 3 = 7

7=7, therefore it is correct.

What are two benefits of a properly conducted orientation program? **Weegy:** 1. Participants will know what to expect and what is expected of them. 2. Further meetings can be minimized thus saving time and resources. **User:** If your company did not offer an orientation, describe what you would include for future staff in your position. **Weegy:** If my company did not have an orientation I would make a detailed description of my job and everything I am responsible for, in detail. And make sure that it was made available to any new hires for my position. (More)

Explain when to use a dashed line as a boundary when graphing a linear inequality
**Weegy:** The dashed boundary indicates that the points on the boundary are not included
in the region which it bounds.
This would be the case when the inequality says that one side is (more or less) than ...
but not equal to ... [ the other side.

Slope -2/3, y-intercept (0, 1/3) User: 2x – y = 12 **Weegy:** This is an easy mathematical problem. In order to find the slope and the Y intercept of the equation all you need to do is bring the equation in the general form, y = mx + c. It will become y = 2x - 5. [ [ In this case as we can see 2 is the slope and -5 is the y intercept. ] ] **User:** (8, 0), m = - 3 **Weegy:**
((3 / 5) * 0.6) - ((2 / 3) * 0.15) = 0.26 Thanks for asking Weegy. **User:** Parallel to 3x – y =7 and passes through (- 1, 0) **Weegy:** (3x-2) squared is 9x^2 - 12x + 4. **User:** 5x - 6y =19 6x + 8y = -5

When graphing y **Weegy:** y>x2-x+1 is a polynomial function differentiate it once and chek in which intervals it is an increasing and in which intervals it is decreasing..
further plot y=5 which i guess is a horizontal line cutting y axis at 5 and shade the region below this [ line..
through the common region from both the equations' graph u can find area and even the point of common solution ] **User:** When we graph the inequality 4x - 3y?_ 0, why can’t we use (0, 0) as a test point? If we test the point (6, -5), do er obtain a false statement or a true one? **Weegy:** What is the number that equation is supposed to total? (More)
