B is the answer i believe.
If
is invertible, then we can simply choose
because for any invertible matrix
by definition we must have
.
We have
, as
which means
is non-singular and has an inverse. The inverse itself would be
Removed sugar is 3/8 and it is 5.81-3.8=2.01 kg
so 3/8 is 2.01 kg
full mass of sugar is 2.01:3*8=5.6 kg
so the mass of container is 5.81-5.6=0.21 kg
Answer: the mass of <span>empty container is 0.21kg</span>
Based on the given data; the table represent an inverse variation and the equation that model the data in the table is y = 8/x
<h3>Variation</h3>
y = k × x
4 = k × 2
4 = 2k
k = 4/2
k = 2
when y = 2 and x = 4
y = k × x
= 2 × 4
y = 8
y = k/x
4 = k / 2
8 = k
when y = 2 and x = 4
y = k/x
2 = k/4
2 × 4 = k
k = 8
So,
y = k/x
y = 8/x
