Solve the system of equations -12x-5y=40 12x-11y=80
Gwar [14]

Answer:

The answer is (-5/24, -7.5).

Step-by-step explanation:

There are two methods to solving a system of equations - substitution or elimination.  In this example, we can use elimination since the coefficients of 'x' are opposite signs.  To complete elmination, we simply add the equations together:

-12x - 5y = 40

<u>+ 12x - 11y = 80</u>

-16y = 120

Use inverse operations to solve for 'y' by dividing both sides by -16 to get       y = -7.5.

Next, plug in the value of 'y' into one of the equations and solve for 'x':

-12x  - (5)(-7.5) = 40 or  -12x + 37.5 = 40, now subtract 37.5 from both sides:  -12x + 37.5 - 37.5 = 40 - 37.5 or -12x = 5/2.  Lastly, divide both sides by -12 to solve for x, x = -5/24.

Someone help me with all of this
Gre4nikov [31]
I’m working on the same thing in school! For number 2, what i would do is start by setting up the scatter plot by using the X and Y table and create origins to place on the graph. ( ex. (1,30) for your first one ). Also, remember to write in the laps completed and calories burned. Next, estimate a line that meets as many points as possible. ( I would use the completed scatter plot in number 3 for an example for how to draw the line ). And that’s all I can help you with :( I forgot how to do the equation part because I just started with this on Monday. Hope this helps!

A parallelogram is shown below:
joja [24]

Answer:

part A. area = L X H

9 x 8/9 = 72/9 = 8 square feet

Part B. Draw a line diagonally either between Point A & C or B & D, this would make 2 triangles.

the area of the triangle would be half of the full area so 8 / 2 = 4 feet square
