7 0

4x² + 23x = -28

4x² + 23x + 28 = 0 move all terms to one side.

4x² + 16x + 7x + 28 = 0 split the second term into two terms

4x(x + 4) + 7(x + 4) = 0 factor.

(x + 4)(4x + 7) = 0 factor.

x = -4, -7/4

hope this helps, God bless!

Determine whether each equation is a linear equation. Write yes or no. If yes, write the equation in standard form. 12x = 7y - 1

Anna71 [15]

Answer:

Yes, this is linear.

y = -4x

Step-by-step explanation:

12x = 7y - 10y

12x = -3y

-3y = 12x

/ -3 /-3

y = -4x + 0

Use the quadratic function f(x) = 2x^2 + 4x - 15. Find any x intercepts.

8_murik_8 [283]

So for this function we will be using the quadratic formula, which is $x=\frac{-b+\sqrt{b^2-4ac}}{2a},\frac{-b-\sqrt{b^2-4ac}}{2a}$ , to solve. a = x^2 coefficient, b = x coefficient, and c = constant. Using our equation, we can solve for the zeros (x-intercepts) as such:

$x=\frac{-4+\sqrt{4^2-4*2*(-15)}}{2*2},\frac{-4-\sqrt{4^2-4*2*(-15)}}{2*2}\\ \\ x=\frac{-4+\sqrt{16-(-120)}}{4},\frac{-4-\sqrt{16-(-120)}}{4}\\ \\ x=\frac{-4+\sqrt{136}}{4},\frac{-4-\sqrt{136}}{4}\\ \\ x=1.92,-3.92$
