Subtract -b+3 from -11-4

Mathematics
1 answer:
NeX [460]3 years ago
3 0
-11-4 - (-b+3)
Distribute the negative sign
-11-4+b-3
Simplify like terms -11, -4, and -3, making sure to remember their sign.
-11-4-3 = -18
So the answer would be b-18 or -18+b.

Which value of y mAkes the equation below true. 3y+8-7y=11
victus00 [196]
We have
3y+8-7y=11
First, we can combine like terms 3y and -7y to get -4y.
Then, we have-4y+8=11 We could then subtract 8 on both sides to get -4y=3
Finally,  we isolate y completely by dividing both sides by -4, to get
y=- \frac{3}{4}

 student found the slope of a line that passes through the points (1, 14)and (3, 4) to be 5. What mistake did she make?
vladimir2022 [97]
Y2-y1/x2-x1
(1,14) & (3,4)
y2= 4
y1=14
x2=3
x1=1

So....

(4-14)/(3-1) = -10/2 = -5

The answer should be negative instead of positive, she probably subtracted 4 from 14 instead.

Z^m-n (z^m+ z^m+n + z^n)
rusak2 [61]

Answer:Your left hand side evaluates to:

m+(−1)mn+(−1)m+(−1)mnp

and your right hand side evaluates to:

m+(−1)mn+(−1)m+np

After eliminating the common terms:

m+(−1)mn from both sides, we are left with showing:

(−1)m+(−1)mnp=(−1)m+np

If p=0, both sides are clearly equal, so assume p≠0, and we can (by cancellation) simply prove:

(−1)(−1)mn=(−1)n.

It should be clear that if m is even, we have equality (both sides are (−1)n), so we are down to the case where m is odd. In this case:

(−1)(−1)mn=(−1)−n=1(−1)n

Multiplying both sides by (−1)n then yields:

1=(−1)2n=[(−1)n]2 which is always true, no matter what n is
