Which is the best approximation for the solution of the system of equations?

y = x + 1
y = 3x – 2

Answer with Explanation:

The given system of equations are

y=x+1------(1)

y = 3 x -2--------(2)

Substituting the value of y from equation 1 in equation 2

→x +1= 3 x -2

→x-3 x =-2 -1

→ -2 x= -3

x=1.5

Substituting the value of, x in equation 1

y=2.5

Ordered Pair (x,y)=(1.5, 2.5)

⇒The given options are

(0.45, 0.88)

(0.88, 0.65)

(0.88, 1.1)

(1.3, 0.88)

None of the Options are best Approximation of calculated Ordered Pair (x,y)=(1.5, 2.5).

square

step-by-step explanation:

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)
