Grace made tables of values to solve a system of equations. First, she found that the 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. X y=-4x+ 3 y-3x-1 0.5 1 0.5 0.6 0.6 0.8 0.7 0.2 1.1 0.8 -0.2 1.4 0.9 -0.6 1.7 1.0 -1 2 Which ordered pair is the best approximation of the exact solution? O A. (0.6, 0.7) O B. (0.7,0.2) O C. (0.5, 1.2) O D. (0.9, 1.0)

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
