Answer:

y=12 x=4

Step-by-step explanation:

I will be using the elimination method to solve this

*2 y= 3x

*3 y= 2x-4.

2y= 6x

- 3y= 6x-12

-1y= -12. y= 3x

/-1 /-1. 12= 3x

y=12. /3 /3

4=x

Answer:

x = -4

y = -12

Step-by-step explanation:

Since y is 3x,

3x = 2x - 4

On solving we get x as -4

Substitute x and we get y as -12

A right triangle has one leg that measures 7 inches, and the second leg measures 10 inches. How long is the hypotenuse?

faltersainse [42]

Answer:

Hypotenuse≈ $12.21$

Step-by-step explanation:

$\sqrt{7^{2} +10^{2} }$ ≈ $12.21$

to calculate this you would need to find the square root of the first leg squared added to the second leg squared.

the hypotenuse is the longest side of the triangle

Part B: In complete sentences, explain how a circle can be used to find the circumcenter of the triangle graphed below.

Karo-lina-s [1.5K]

Answer:

Step-by-step explanation:

Part B:

The center of the circumscribed circle around a triangle is equidistant from vertices of that triangle. To find the circumcenter need to draw at least two perpendicular bisectors to the sides of the given triangle. Point of intersect of them is center of the circumscribed circle.

Part C:

Coordinates of the midpoint of line BC ( y = - 1 ) are

( $\frac{-6+2}{2}$ , $\frac{-1-1}{2}$ ) = ( - 2 , - 1 ) and the equation of the line ⊥ to BC is x = - 2
