Answer:
x>-1
Step-by-step explanation:
Answer:
use FOIL- Firsts Outsides Insides Lasts
- Multiply the -4 and -3 as they are the first numbers of each brackets -4x-3=12
- Next the outsides so -4x6i as they are on the outskirts of each brackets -4x6i= -24i
- Insides so 3i and -3 as they are in the centre of the two brackets 3ix-3= -9i
- Lasts so 3i and 6i as they are at the end of each bracket 3ix6i=18i^2 ( i squared)
- add the answers together - 12+-24i+-9i+18i^2= 12-24i-9i+18i^2
- Simplify by adding like terms which is -24i and -9i.
<h3>12+-33i+18i^2 is the answer </h3>
1 * 7 + 2 * 1 + 3 * 3 + 4 * 2 + 5 * 2 =
7 + 2 + 9 + 8 + 10 =
36
Now we need to divide 36 by the total frequency: 7+1+3+2+2=15
36 / 15 = 2.4
Answer:
Step-by-step explanation:
the first thing you have to do is to get the x and the y axis and add them to then decrease that by o,5 and then you get f of which you multiply it by 2 adn you get your answer.
