4x - 3(x + 5) > 7 - 4(x + 6) |use distributive property; a(b + c) = ab + ac

4x - 3x - 15 > 7 - 4x - 24 |combine items

x - 15 > -4x - 17 |add 15 to both sides

x > -4x - 2 |add 4x to both sides

5x > -2 |divide both sides by 5

x > - 2/5

What are the values of the coefficients and constant term of 0 = 4 – 7x2 + x in standard form?

katen-ka-za [31]

ANSWER

$a = - 7$

$b = 1$

$c = 4$

EXPLANATION

The given quadratic equation is:

$0 = 4 - 7 {x}^{2} + x$

We rewrite in the standard quadratic equation form to obtain,

$- 7 {x}^{2} + x + 4 = 0$

Comparing this to the general standard quadratic equation.

$a {x}^{2} + bx + c = 0$

We have my

$a = - 7$

$b = 1$

$c = 4$
