Graph the following system of equations and find the x-coordinate of the solution.

Veseljchak [2.6K]

The x - coordinate of the solution is $x=-2$

Explanation:

The two equations are $3 x+3 y=3$ and $y=-\frac{1}{2} x+2$

Let us determine the value of the x - coordinate using the substitution method.

Let us substitute $y=-\frac{1}{2} x+2$ in the equation $3 x+3 y=3$ , we get,

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

Multiplying the term 3 within the bracket, we get,

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

Subtracting both sides of the equation by 6, we get,

$3x-\frac{3}{2} x=-3$

Taking LCM on the LHS of the equation, we get,

$\frac{6x-3x}{2} =-3$

Subtracting the numerator, we have,

$\frac{3x}{2}=-3$

Multiplying both sides of the equation by 2, we have,

$3x=-6$

Dividing both sides of the equation by 3, we get,

$x=-2$

Thus, the x - coordinate of the solution is $x=-2$

From the top of a 200 meters high building, the angle of depression to the bottom of a second building is 20 degrees. From the s

netineya [11]

It says that the buildings together are 200 meters high and from the top pf the first to bottom of the second is 20(whole building) but from the top of the first to second is 10 (half of the building ) so if the degree if half the high will be half too so the high will be 200/2 = 100 meters high for each buildings :))
i hope this is helpful

I need the y values i guessed them but they are wrong<br> y=3x

lara [203]

Y = 3x
x(3) = y

1) (-2) 3 = -6

2) (-1) 3 = -3

3) (0) 3 = 0

4) (1) 3 = 3

-6, -3, 0, and 3 respectively.
