PLEASE HELP!!!20 POINTS!Alicia made tables of values to approximate the solution to a system of equations.First she found the x-
values of the solution was between 0 and 1 and then she found that it was between 0 and 0.5. Next, she made this table.

Answer:
C. (0.4, 2.9)
Explanation:
One way is to <em>solve the simultaneous equation</em>s algebraically.
(1) y = -3x +4
(2) y = 5x+1 Subtract Equation (1) from Equation (2)
0 = 8x - 3 Add 3 to each side
3 = 8x Divide each side by 8
x = 3/8 Convert to a decimal
x = 0.375 Substitute x into Equation (2)
y = 5(3/8) + 1 Remove parentheses
y = 15/8 + 1 Combine terms
y = 23/8 Convert to a decimal
y = 2.875
The exact solution is (0.375, 2.875).
The approximate solution is (0.4, 2.9).
===============
Alicia could also plot the two graphs and note their point of intersection.
Her approximate solution is the <em>green point </em>at (0.4, 2.9).
