Multiply everything in the parenthesis by 3.

9x - 24 = 4x + 6

Add 24 to both sides.

9x = 4x + 30

Subtract 4x from both sides.

5x = 30

Divide both sides by 5.

x = 6

Hope this helps!

The line l with equation x - 2y + 2 = 0 crosses the y-axis at the point P. The line
Sauron [17]

Answer:

Area of ΔPQR is 28 units²

Step-by-step explanation:

-P is the point with coordinates ( 0, y-intercept for line x-2y+2 =0)

-rearrange the equation in the point-slope form y=mx+b  to find the y coordinate of the point P( 0, b)

x-2y+2 = 0, subtract x and 2 from both sides

-2y = -x-2, divide by -2 both sides

y= (1/2)x +1 so b=1 and P (0, 1)

-Q  is the point with coordinates ( 0, y-intercept for line 3x+y -15 =0)

-rearrange the equation in the point-slope form y=mx+b  to find the y coordinate of the point Q( 0, b)

3x +y -15 =0, subtract 3x and add 15 to both sides

y= -3x +15 so b=15 and Q(0,15)

-R is the intersection of the two lines so is the solution of the system of equations y= (1/2)x +1 and y= -3x +15

(1/2)x +1 =  -3x +15, add 3x and subtract1

(1/2) x+3x = 15-1, combine like terms

(7/2)x = 14 , multiply both sides by 2

7x = 28, divide both sides by 7

x= 4

y= (1/2)x +1 = (4/2) +1 =3 so R(4,3)

- the area of ΔPQR is (base *height)/2

base= 15-1= 14

height = 4

A= (14*4)/2 = 14*2 = 28

Find the value for the given variables. Give the variables in simplest radical form.
Svetach [21]

\huge\boxed{ \boxed{\mathrm{ \underline{Answer}࿐  }}}

The given triangle is a right angled triangle,

so let's apply trigonometry here :

  • \sin(30)   =  \dfrac{7}{y}

  • \dfrac{1}{2}  =  \dfrac{7}{y}

  • y = 7 \times 2

  • y = 14 \:  \: units

Now,

  • \cos(30)  =  \dfrac{x}{y}

  • \dfrac{ \sqrt{3} }{2}  =  \dfrac{x}{14}

  • x =  \dfrac{14 \sqrt{3} }{2}

  • x = 7 \sqrt{3}

  • x = 12.12 \:  \: units
