Which is the best approximation for the solution of the system of equations? y = x + 1 y = 3x – 2
2 answers:
B. (0.88,0.65) would be the closest approximation for this system of these choices.
The given equations are y = x + 1and y = 3x – 2
Substituting y value in equation 1 from 2 we have :
3x-2=x+1
Subtracting x both sides
3x-x-2=1
2x-2=1.
Adding 2 both sides
2x=3
Dividing by 2
x=1.5.
Substituting x value in y=x+1
y=1.5+1.
y=2.5.
Solution is (1.5,2.5)
The approximate solution is B. (0.88, 0.65)

Answer:
f(fx) = 64x + 81
Step-by-step explanation:
f(x) = 8x + 9
f(fx) = 8(8x+9) + 9
= 64x + 72 + 9
= 64x + 81

Answer:
x=-1/3, y=-13/3. (-1/3, -13/3).
Step-by-step explanation:
y=x-4
4x-y=3
------------
4x-(x-4)=3
4x-x+4=3
3x+4=3
3x=3-4
3x=-1
x=-1/3
y=-1/3-4
y=-1/3-12/3=-13/3
