Hello : 
<span>y²-2y=-9/2
(y²-2y +1) -1  = -9/2
(y-1)² = -7/2
in : R  no solutions
in : C  two solutions 
y-1 =-(</span><span>√</span>7/2)i   or y-1 = (√<span>7/2)i
y = 1  -(</span>√7/2)i     or  y = 1+(√<span>7/2) i    because : -7/2 =(7/2)i²... i² = -1 
</span>

PLEASE HELP <br>If BC DA, then which segment is the shortest side?​
NeX [460]

The length of the shortest side is DC

<h3>How to determine the shortest side?</h3>

As a general rule in triangle;

The smallest angle in a triangle is opposite the shortest side.

Similarly, the largest angle in a triangle is opposite the largest side.

From the given figure of triangles, the smallest angle is angle CBD with a measure of 47 degrees.

The side opposite this angle is side length DC

Hence, the length of the shortest side is DC

ann is grouping 38 rocks, she can put into groups of 10 rocks or as single rocks what are the different ways she can group them
inysia [295]
Since Anna is either grouping them as single rock or as group of 10, we need to find the maximum number of groups of 10 as follows: 38/10 = 3.8

This means that Anna can make maximum 3 groups of 10 rocks.

Based on this, the different ways to group the rocks are as follows:
- 3 groups of 10 and 8 (which are calculated as: 38-30) single rocks
- 2 groups of 10 and 18 (which are calculated as: 38-20) single rocks
- 1 group of 10 and 28 (which are calculated as: 38-10) single rocks
- 0 group of 10 and 38 (which are calculated as: 38-0) single rocks

WILL NAME BRAINLIEST-PLEASE DONT ANSWER IF YOU DONT KNOW
mojhsa [17]

Answer:

Infinite Solutions

Step-by-step explanation:

x + 2y = 10

6y = 3x - 30

To solve for x and y we use substitution method

Let's solve the first equation for x

x + 2y = 10

Subtract 2y on both sides

x = 10 - 2y

Now plug in x in second equation

6y = -3x + -30

6y = -3 (10-2y) - 30

6y = -30 + 6y - 30

6y = 6y

Both sides are the same, so both x and y have infinite solutions.
