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).
