Hi @alyygirl. Hope you have been well. Let's work through this one? Or are you looking for just an answer...?
OpenStudy (anonymous):
lets work through
OpenStudy (anonymous):
-4 [(-3)(-1) - -1^6(-4)] / (4-10)^2
Let's split it up into manageable sections so we can do it step by step.
I didn't change anything, just added a bunch of spaces to separate the parts, can you see that so far?
OpenStudy (anonymous):
yep

Ok so we can simplify the (-3)(-1) to be 3 right?
-4 [ 3 - -1^6(-4)] / (4-10)^2
Simplifying the -1^6(-4) in the last part I showed.

which is -4
OpenStudy (anonymous):
-4 [3 - (-4)] / (4-10)^2
- * -
+
3 + 4
7
-4 [ 7 ] / (4-10)^2
I really hope this is making sense. Do you have any questions about how I came to
-4(7)/(4-10)^2 so far?
OpenStudy (anonymous):
no im good
OpenStudy (anonymous):
That's awesome!! I felt like I was doing a horrid job haha
OpenStudy (anonymous):
nope but the way its written is confusing lol

(4-10)^2 = -6^2 = 36
-4(7)/36
-28/36
-14/18
-7/9
Our answer should be -7/9 but I'm pretty sure I made a mistake somewhere...
OpenStudy (anonymous):
ok so it is -7/9 or your not sure?
OpenStudy (anonymous):
I am not 100% sure. More like 25%. Let me do it on paper real quick ok? =0P
OpenStudy (anonymous):
ok lol
OpenStudy (anonymous):
Yep that's right!

another question?
OpenStudy (anonymous):
actually check my work
OpenStudy (anonymous):
Sure.
OpenStudy (anonymous):
Evaluate the following expression when a = -3, b = 1, c = 3:
-3bc over
bc^2 - c
OpenStudy (anonymous):
-39/166?

\[-3bc/bc ^{2} - c\]
Right?
OpenStudy (anonymous):
yep
OpenStudy (anonymous):
\[-3(1)(3)/(1)(3^{2}) - 3\]
Where is the a in this equation lol?
OpenStudy (anonymous):
expression, not equation
OpenStudy (anonymous):
its the -3 i guess

idk weird
OpenStudy (anonymous):
9/6 or 3/2 is the reduced form of that expression.
