subtract polynomials (-6.7x2 + 2.3xy + 5.2) - (-14.9x2 - 3.5xy + 7.1)
(-6.7x^2 + 2.3xy + 5.2) - (-14.9x^2 - 3.5xy + 7.1) = -6.7x^2 + 14.9x^2 + 2.3xy + 3.5xy + 5.2 - 7.1; = 8.2x^2 + 5.8xy + 1.9

(-6.7x^2 + 2.3xy + 5.2) - (-14.9x^2 - 3.5xy + 7.1)

= -6.7x^2 + 14.9x^2 + 2.3xy + 3.5xy + 5.2 - 7.1;

= 8.2x^2 + 5.8xy + 1.9

(2a)3 = _____ This expression without exponents is?
Updated 3/25/2016 12:21:13 AM
This expression without exponents is 8a^3.
(2a)^3
= (2a)(2a)(2a)
= 8a^3
This answer has been flagged as incorrect.

(2a)^3 = (2a)(2a)(2a)
This expression without exponents is (2a)(2a)(2a).
Input in standard form the equation of the given line. The line that passes through (-2, 4) and is parallel to x - 2y = 6

The standard form the equation of the given line. The line that passes through (-2, 4) and is parallel to x - 2y = 6 is x - 2y = -10.
slope of x - 2y = 6 is 1/2;
y - 4 = 1/2(x + 2);
2y - 8 = x + 2;
x - 2y = -10

The line that passes through (-1, -3) and (2, 1)
Updated 3/24/2016 11:24:05 PM
The line that passes through (-1, -3) and (2, 1) is 4/3.
slope = (1 + 3)/(2 + 1) = 4/3
