Answer:

8 square units

Step-by-step explanation:

Area of a rectangle= lenght x width

locating the four points on a Cartesian plane

lenght = BC= AD = (0,4)->(4,4) = 4units

width = AB = CD = (0,2)-> (0,4) = 2units

Area of rectangle = 4units x 2units = 8 square units

The point (7, 8) is the solution of which of the following systems of equations?
Alex73 [517]

Option 4

<u>V</u><u>e</u><u>r</u><u>i</u><u>f</u><u>i</u><u>c</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u><u>:</u><u>-</u>

\\ \sf\longmapsto x-7y=-49

\\ \sf\longmapsto 7-7(8)=-49

\\ \sf\longmapsto 7-56=-49

\\ \sf\longmapsto -49=-49

And

\\ \sf\longmapsto 10x+9y=142

\\ \sf\longmapsto 10(7)+9(8)=142

\\ \sf\longmapsto 70+72=142

\\ \sf\longmapsto 142+142

Hence verified

Answer:

20

Step-by-step explanation:

You need to create two equations for each company and then set them equal to each other. The keywords base fee means you will pay this amount regardless, so this amount stays constant and it will be the constant in the equation.  The other keyword is per. Per will link the variable with the coefficient.

The first equation for company M:

y = 12x + 60

The second equation for company N:

y = 9x + 120

Set the equations equal to each other.

9x + 120 = 12x + 60

Solve for x. I am going to subtract 9x from both sides first.

9x - 9x + 120 = 12x -9x +60

120 = 3x +60

Now, I will subtract 60 from both sides.

120 - 60 = 3x + 60 - 60

60 = 3x

Finally, I will divide both sides by 3

60/3 = 3x/3

x = 20

20 is how many guests it will take for the total cost to be the same.

<span>you need to set up the equations solve for x or y. and substitute. I can give you the starting equations, but i cant find the answer and I don't remember how to do all the steps, but the first two equations (the ones you use to solve for x or y to use to solve for a number to subsitute. x-12=y y-14=3x and there should be one more for that they met two years ago.</span>
