Answer:
405
Step-by-step explanation:
It tells in the table.
The inverse of the matrix
is the matrix
.
The inverse of a matrix A is calculated by the formula:
A' = (1/|A|)(Adj A),
where A' represents the inverse of matrix A,
|A| represents the determinant value of matrix A, and
Adj A represents the Adjoin matrix of matrix A.
So, to calculate the inverse of the matrix
, we will first calculate its Adj.
Adj =
=
.
Now, we calculate |A| = 11*(-1) - (-5)*3 = -11 + 15 = 4.
Therefore A' = (1/|A|)(Adj A),
or, A' =
,
or, A' =
.
Therefore, the inverse of the matrix
is the matrix
.

Answer:
y-intercept=-5
Step-by-step explanation:
y=mx+b m/slope=3/2 the point is (x,y)/(4,1)
1=3/2(4)+b
1=12/2+b
1=6+b
-6-6
-5=b
Adding on to the previous, estimate FRACTIONS of the chart, and then figure out the percentage of those fractions
