Answer:
13
Step-by-step explanation:
To find the determinant you subtract the the leading diagonal from the non-leading diagonal.
(4x-2)-(-7x3)
-8 - -21
NB A negative beside a negative gives you a positive number.
-8+21
=13
Answer:
-5.1
Step-by-step explanation:
Subtract 5.1 from both sides.
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>
Answer:
hope it helps
Step-by-step explanation:
The given inequality is
The sign of inequality is ≤, it means the points on relation line lie in the solution set.
The related equation of the inequality is
At x=0,
At x=1,
Plot the points (0,0) and (1,-2) on a coordinate plane.
The sign of inequality is ≤, it means we have shade below the line.
The point (-2,4) and (3,-6) are in solution set because,
(True)
(True)
Therefore option A is correct.
The points (1,2) and (1,3) are not in the solution set because,
(False)
(False)
