Answer:
A
Step-by-step explanation:
1 feet=1/3 yards
7 feets = 7*(1/3) yards
7 feets=7/3 yards
7 feets=2 1/3 yards
X + 9 = 2 ( x - 1 )²
x + 9 = 2 ( x² - 2 x + 1 )
x + 9 = 2 x² - 4 x + 2
- 2 x² + 4 x + x - 2 + 9 = 0
- 2 x² + 5 x + 7 = 0 / * ( -1 )
Answer:
A ) 2 x² - 5 x - 7
Answer:
4a.)
so the equation for this can be:
3/4 divided by 1/8
also, how many times can 1/8 go into 3/4
3/4=6/8
1/8 goes into 6/8 6 times, so 6 cupcakes out of the 8 cupcakes(or however many cupcakes there are - the problem doesn't specify that)
4b.)
3/4 ÷ 1/8
10.)
each square is 2 units wide(or long-whatever you wanna call it)
i don't really know how to explain this one, but i can just give you my answer (you can jut count up the squares along the outside of the polygon-the meaning of perimeter)
76 units
the bottom left one (i cant read the question number sorry)
1/10 of 237=
1/10*237=
237/10=
23.7
19.)
reflection pretty much means mirroring, so if you add the distance from E to the y axis and M to the y axis, you will get 10 (|-5|+|5|)
point m is in the 1st quadrant (sorry i don't really know how to explain this one either)
hope this helped!!

Answer: 1.3</h3>
========================================
Work Shown:
The two points we have are and
Apply the distance formula
-------------------------
A shortcut is possible by subtracting the y coordinates of the two points, and making the result positive through the use of absolute value.
So we either say
|y1-y2| = |1.2-2.5| = |-1.3| = 1.3
or,
|y2 - y1| = |2.5 - 1.2| = |1.3| = 1.3
We get the same result. This shortcut is valid because the x coordinates of both points are the same.
X=+-4
positive and negative 4
