8(x+6)−10+r=3(x+12)+5x

Mathematics
1 answer:
larisa86 [58]4 years ago
5 0

Answer:

ne solution was found :

                  r = -2

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :  

               8*(x+6)-10+r-(3*(x+12)+5*x)=0  

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 (((8•(x+6))-10)+r)-(3•(x+12)+5x)  = 0  

Step  2  :

Equation at the end of step  2  :

 ((8 • (x + 6) -  10) +  r) -  (8x + 36)  = 0  

Step  3  :

Equation at the end of step  3  :

 r + 2  = 0  

Step  4  :

Solving a Single Variable Equation :

4.1      Solve  :    r+2 = 0  

Subtract  2  from both sides of the equation :  

                     r = -2  

One solution was found :

                  r = -2

Find the coordinates of the circumcenter for ∆DEF with coordinates D(1,3) E (8,3) and F(1,-5). Show your work.
luda_lava [24]

Answer: The coordinates of the circumcenter is (\frac{9}{2}, -1).

Explanation:

The coordinates of triangle DEF are D(1,3) E (8,3) and F(1,-5).

Distance formula,

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

DE=\sqrt{(8-1)^2+(3-3)^2}=7

FE=\sqrt{(1-8)^2+(-5-3)^2}=\sqrt{7^2+8^2}

DF=\sqrt{(1-1)^2+(-5-3)^2}=8

Since triangle follows pythagoras theorem,

(DF)^2+(DE)^2=(FE)^2

Therefore the given triangle is a right angle triangle.

Or plot these points on a coordinate plane. From the figure we can say that the triangle DEF is a right angle triangle.

The circumcenter of a right angle triangle is the midpoint of the hypotenuse.

The hypotenuse is EF. The midpoint of EF is,

Midpoint =(\frac{8+1}{2}, \frac{3-5}{2} )=(\frac{9}{2}, -1)

Therefore, the coordinates of the circumcenter is (\frac{9}{2}, -1).
