we are given to find
we know that
where
i is number of rows
j is number of column
Here , we get
i=2
and j=3
so,
means second row and third column
we can look at matrix and find element
we can see that
that element is -21
so,

Answer:
y = 2x +13
Step-by-step explanation:
when 2 lines are perpendicular, the product of the two gradients is -1
i.e. m x m1 = -1
so from 10y + 5x = 3, the gradient m is -0.5
m1 = -1 / -0.5 = 2
using m1 = 2 and pt(-7,-1),
the eqn is y = (m1)x +c
-1 = 2(-7) + c
c= 13
thus y = 2x +13
Answer:Answer is D (3,1/2)
Step-by-step explanation:
It was right on edg.
(25/100)*56 = (x/100)*42
14 = (21/50)x
x = 33.333333
