Answer:
-8
Step-by-step explanation:
-4 x 8 = -32
8 x 3 = 24
-32 + 24 = -8
Hope this is right and helps!
Nice use of brackets. We know exactly what you mean.
(10 - 7 + 2) / (-2 + 1) Notice that with an even number of - signs, you get a plus and with and odd number you get a minus.
(5) / (-1) = - 5 answer
Edit
Numerator
10 does not change.
+ - 7 Here a plus and a minus are put together. There is 1 minus sign which is an odd number of minus signs so the 7 is minus
- - 2 Here there are 2 minus signs. They become plus because 2 is even, and an even number of minuses become a plus so you have +2
10 - 7 + 2 = 5
Denominator
-2 does not change. It remains minus 2.
- - 1 There are 2 minus signs so this becomes plus 1.
- 2 + 1 = - 1
Numerator over denominator = 5/-1 = - 5. I'll probably run out of editing time. If you still don't understand, try and pinpoint the problem and we'll keep trying until you do see it. This question is worth it.
1) 2x+4y=10
3x+5y=14 .
find d2, dx2, and dy
2) Solve the system of equations algebraically and show your work.
2x + 3y = 12
2x - y = 4
3) Which of the ordered pairs (5,5),(5,0) and (-3,2) can be found in the shaded solution area for the system of inequalities below? (The ordered pair must be in the double shaded region or it is not a solution of the system.)
x+2y<6
2x+y > or equal too 9 so yea hoped this helped
Answer:
It would last 7 1/2 weeks if i'm correct
Answer:
a) p = 352/700 = 0.5029
b) p = 348/700 = 0.4971
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
There are 700 shoppers.
151 + 201 = 352 were happy with the service received.
133 + 215 = 348 were not happy with the service received.
(a) A shopper was happy with the service received.
352 happy out of 700
p = 352/700 = 0.5029
(b) A shopper was unhappy with the service received.
348 unhappy out of 700
p = 348/700 = 0.4971
