Answer:

Step-by-step explanation:

hello :

(x² - 10x) + (y² - 2y) + 15 = 0

(x² - 10x+25-25) + (y² - 2y+1-1) + 15 = 0

(x² - 10x+25)-25 + (y² - 2y+1)-1 + 15 = 0

(x-5)²+(y-1)² = 11

the center is (5;1) and radius √11

What is x in this equation- 3/2x-7=-11

Sunny_sXe [5.5K]

3/2x-7=-11

We move all terms to the left:

3/2x-7-(-11)=0

Domain of the equation: 2x!=0

x!=0/2

x!=0

x∈R

We add all the numbers together, and all the variables

3/2x+4=0

We multiply all the terms by the denominator

4*2x+3=0

Wy multiply elements

8x+3=0

We move all terms containing x to the left, all other terms to the right

8x=-3

x=-3/8

Determine if the two triangles are congruent.

stiks02 [169]

Answer:

SAS

Step-by-step explanation:

The two triangles share a side, so that would be reflexive to show that side is congruent. Also, keep in mind that all right angles are congruent! The picture already tells us that the two outer side are congruent. So in conclusion, the two angles are congruent by SAS.

Hope this helps! :)
