Answer:
The absolute value of Point B labelled on the number line is 1.6.
Step-by-step explanation:
In a number line
Coordinate of point A = -2.2
Coordinate of point B = -1.6
Coordinate of point C = 1.2
We need to find the absolute value of Point B labelled on the number line.
Absolute value : Absolute value of a real number is the non-negative value of that number. Let x be a real number, then
The absolute value of Point B is
Therefore the absolute value of Point B labelled on the number line is 1.6.
Answer:
Option b is correct (8,13).
Step-by-step explanation:
7x - 4y = 4
10x - 6y =2
it can be represented in matrix form as
A=
X=
B=
i.e, AX=B
or X= A⁻¹ B
A⁻¹ = 1/|A| * Adj A
determinant of A = |A|= (7*-6) - (-4*10)
= (-42)-(-40)
= (-42) + 40 = -2
so, |A| = -2
Adj A=
A⁻¹ = / -2
A⁻¹ =
X= A⁻¹ B
X=
X=
X=
X=
x= 8, y= 13
solution set= (8,13).
Option b is correct.
