Answer:

The answer is 4y.

Step-by-step explanation:

First you would solve the parentheses, which would be -1(-3y) which would equal positive 3y, and y+3y=4y. I apologize if I misunderstood the problem ^^

Answer:

7. is G

8. f(4)=-120

Step-by-step explanation:

7. les do f(0)=4 since its the easiest

F. f(0)=0.4(0+5)(0-2)

0.4*-2*5=-4 NOT IT. the ans. is +

G. f(0)=-0.4(0+5)(0-2)

-0.4*-2*5=4 YESSSSSS

H. f(0)=-0.4(0-5)(0+2)

-0.4*2*-5=4 YESSSSSS

J. f(0)=0.4(0-5)(0+2)

0.4*2*-5=-4 NOT ITTTT

so G n H

Put both equation=0

G. 0=-0.4(x+5)(x-2)

x=-5,2 YASSSS this is the ans.

Solve the equation using the quadratic formula. Enter each solution in simplest form.

For this case we have the following quadratic equation:

$x ^ 2-4x + 23 = 0$

The solutions will be given by:

$x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}$

Where:

$a = 1\\b = -4\\c = 23$

Substituting the values we have:

$x = \frac {- (- 4) \pm \sqrt {(- 4) ^ 2-4 (1) (23)}} {2 (1)}\\x = \frac {4 \pm \sqrt {16-92}} {2}\\x = \frac {4 \pm \sqrt {-76}} {2}\\x = \frac {4 \pm \sqrt {76i ^ 2}} {2}\\x = \frac {4 \pmi \sqrt {76}} {2}\\x = \frac {4 \pmi \sqrt {2 ^ 2 * 19}} {2}\\x = \frac {4 \pm2i \sqrt {19}} {2}\\x = 2 \pm i\sqrt {19}$
