Answer:

(7, 13/3)

Step-by-step explanation:

y=\frac{1}{3} x+2\\   Line up the equations on top of each other

y=\frac{4}{3} x-5

-4*[y=\frac{1}{3} x+2]   Multiply the top equation by -4 in order to cancel out the x variable

-4y=-\frac{4}{3} x-8   Switch out the first equation for this one

-4y=-\frac{4}{3} x-8   Line up the equations

    y=\frac{4}{3} x-5

-3y=-13   Add the two equations top to bottom, left to right

    y=\frac{13}{3}

Now that you've found y, you need to find x. Just plug in the y-value to either of the equations in Step 1:

The first equation has smaller numbers, so let's use that one.

\frac{13}{3} =\frac{1}{3} x+2

To make it easier you can multiply all the terms in the equation by 3:

13=x+6

 7=x

The x- and y- values together give a solution of ( 7, \frac{13}{3} )

Solve systems of equations by graphing. A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system.

What is the best estimate for this sum?
Serggg [28]
It's 7/24 so about 0.292
therefore it will be close to 1/4

or you calculate 1/8 = 0.125 and 1/6 = 0.1666 adds up close to 1/4

Answer:

n = 6\sqrt{3}

Step-by-step explanation:

you can create this proportion:

18/n = n/6

cross-multiply:

n² = 108

n = \sqrt{108}

\sqrt{108} = \sqrt{4}·\sqrt{9}·\sqrt{3} = 2·3·\sqrt{3} or 6\sqrt{3}
