Answer: Independent variable = c
Dependent variable = v
Step-by-step explanation:
- The independent variable does not depend on any other variable.
- Dependent variable dependent on another variable.
Given variables:
c = the number of Nora's coworkers who attend the picnic
v = the number of veggie burgers
Here the number of burgers required is dependent on the number of Nora's coworkers who attend the picnic.
Therfeore, Independent variable = c
Dependent variable = v
Answer:
ur in rsm too? i have the same question sorry -_-
Step-by-step explanation:
STEP BY STEP:
-5 times 1 is -5
-5 times 11 which is positive makes it -55
-55 times 4 makes it -220
Hope this helps!
where det(<em>A</em>) = 1×1 - 2×1 = -1.
where det(<em>B</em>) = 0×2 - (-1)×1 = 1. Then
On the other side, we have
and det(<em>AB</em>) = det(<em>A</em>) det(<em>B</em>) = (-1)×1 = -1. So
and both matrices are clearly the same.
More generally, we have by definition of inverse,
where 
is the identity matrix. Multiply on the left by <em>A </em>⁻¹ to get
Multiplication of matrices is associative, so we can regroup terms as
Now multiply again on the left by <em>B</em> ⁻¹ and do the same thing:
