The solution is: (6,0)

Step-by-step explanation:

Given equations are:

$x+6y = 6\\y = \frac{1}{3}x-2$

Part A:

The graph is made using the online tool Desmos.

The graph is attached as a picture

Part B: Solution from graph:

On the graph we can see that both lines intersect at (6,0)

So the solution is x=6 and y=0

Part C: Algebraic Verification

$x+6y = 6\ \ \ \ Eqn1\\y = \frac{1}{3}x-2\ \ \ \ Eqn2$

Putting y= 1/3x-2 in equation 1

$x+ 6(\frac{1}{3}x-2) = 6\\x + 2x-12 = 6\\3x -12 = 6$

Adding 12 on both sides

$3x-12+12 = 6+12\\3x = 18$

Dividing both sides by 3

$\frac{3x}{3} = \frac{18}{3}\\x = 6$

Putting x = 6 in equation 2

$y = \frac{1}{3}(6)-2\\y = 2-2\\y = 0$

Hence,

The solution is: (6,0)

Find the value of x. If your answer is not an integer, leave it in simplest radical form. The diagram is not drawn to scale.

Amiraneli [1.4K]

Answer:

x = 5sqrt(3)

Step-by-step explanation:

This is a right triangle. We can use the Pythagorean theorem to solve

a^2 +b^2 = c^2

5^2 +x^2 = 10^2

25+x^2 = 100

Subtract 25 from each side

25-25 +x^2 = 100-25

x^2 = 75

Take the square root of each side

sqrt(x^2) = sqrt(75)

x = sqrt(3*25)

Remember sqrt(ab) = sqrt(a)sqrt(b)

x = sqrt(5)sqrt(3)

x = 5sqrt(3)
