Question

Ellinor made tables of values to solve a system of equations.First she found that the x-value of the solution was between 0 and 1, and then she found that it was between 0.5 and 1. Next,she made this table.
A.(0.5,-1.8)
B.(0.9,-2.1)
C.(0.7,-1.5)
D.(0.6,-1.4)

Answer 1

A. (0.5,-1.8) is the answer

Answer 2

The best approximation of the solution is represented by the ordered pair, (0.7,-1.5), the correct option is C.

What is an Equation?

An equation is a mathematical statement formed when two algebraic expressions are equated using an equal sign.

The equations are useful in the determination of unknown parameters.

The system of equations are equations that have a common solution.

The equations are:

y = 2x-3

y = -5x +2

The ordered pair that is the best approximation of the solution is the point at which for a given value of x, the system of the equation has the same y value.

From the table, it can be seen that for x = 0.7, the y value for both the equation is similar, -1.5 and -1.6.

Therefore, (0.7, -1.5).
