Answer:
<h3>or infinitely many</h3>
Step-by-step explanation:
simplifying the equation -6x + 8y = 12 dividing by 2 would give us the same equation as
-6 / 2x + 8 / 2y = 12/2
-3x + 4y = 6
Answer:

Step-by-step explanation:
Answer: (13,-7)
Step-by-step explanation:
By using the formula 
is the coordinates of the midpoint.
For finding the midpoint X variable do:

For finding the midpoint Y variable do:
(you can either keep the parenthesis or take them out. Either way, the answer is the same.
Considering coordinate numbers follow the format: (x,y), you'll simply just substitute the numbers found above into their respective places.
x: 13
y: -7
(13,-7).
Answer:
Triangles ABC and MNO are similar by SSS
Step-by-step explanation:
we know that
If two triangles are similar, then the ratio of its corresponding sides is proportional
In this problem
If this problem the corresponding sides are
AB and MN
BC and NO
AC and MO
Verify if the corresponding sides are proportional

substitute the given values

----- is true
so
When two triangles have corresponding sides with identical ratios , the triangles are similar by SSS Similarity
therefore
Triangles ABC and MNO are similar by SSS
Answer:
Center (6 , -5) and radius = 3
Step-by-step explanation:
The Standard equation of circle can be written as
(x - a)² + (y - b)² = r²
with center (a , b) and radius = r
Now from given circle equation
(x - 6)² + (y +5)² = 9
so, from here center of circle (6 , -5) and radius = 3
