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.

C. (0.4, 2.9)

Explanation:

One way is to solve the simultaneous equations 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 green point at (0.4, 2.9).

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

depending on others is critical to survival. my source is apex!
