Answer:
the quickest way would be to "complete the square"
on x^2 + 5x - 7
you will end up with (x+2.5)² = 13.25
or
y = (x+2.5)²-13.25
the vertex
VERTEX: (-2.5,-13.25)
Solution/X-Intercepts: -6.14 AND 1.14

Answer:
ccccccccccc
Step-by-step explanation:
Let n = .234....
Now our job is to get the entire part that repeats on the left of the decimal point.
If we multiply the number by 1000 exactly one 2, one 3 and one 4 will move to the left.
So 1000n = 234.234... now lets remove our original number
-<u> n = -.234...</u> Notice how all the repeaters minus all the repeaters
999n = 234 leaves only the 234 that we move to the left of
the decimal point
Now lets divide both side by 999
<u>999n </u> = <u>234
</u>999 999 this is the answer in unreduced form 9 can go into both = <u>26</u><u>
</u> 111
<u />
Try it on your calculator (divide 26 by 111)
Answer:
C) 50 degrees
Step-by-step explanation:
angles x and 130 degrees are supplementary in that they add up to 180 degrees.
x + 180 - 130 = 50 degrees
The formula for a right triangle is: ab/ 2
The formula for a parallelogram is: bh
