Step-by-step explanation:

3a+3b+c=-20 --(1)

a-3b+2c=9 ------(2)

8a-2b+3c=5 ----(3)

from equ(2)

a-3b+2c=9

a=9+3b-2c

put a in equ(1)&(3)

3a+3b+c=-20

3(9+3b-2c)+3b+c=-20

27+9b-6c+3b+c=-20

12b-5c=-47 --(4)

8a-2b+3c=5

8(9+3b-2c)-2b+3c=5

72+24b-16c-2b+3c=5

22b-13c=-67---(5)

solve equ(4)&(5) simultaneously

and get d value for b and c

then substitute it in

a=9+3b-2c

I would appreciate if my answer is chosen as a brainliest answer

What are the solutions of the equation (2x + 3)2 + 8(2x + 3) + 11 = 0

Tom [10]

Answer:

$x=\frac{-7-\sqrt{5}}{2}$ or $x=\frac{-7+ \sqrt{5}}{2}$

Step-by-step explanation:

The given equation is

$(2x+3)^2+8(2x+3)+11=0$

Let us treat this as a quadratic equation in $(2x+3)$ .

where $a=1,b=8,c=11$

The solution is given by the quadratic formula;

$(2x+3)=\frac{-b\pm \sqrt{b^2-4ac} }{2a}$

We substitute these values into the formula to obtain;

$(2x+3)=\frac{-8\pm \sqrt{8^2-4(1)(11)} }{2(1)}$

$(2x+3)=\frac{-8\pm \sqrt{64-44} }{2}$

$(2x+3)=\frac{-8\pm \sqrt{20} }{2}$

$(2x+3)=\frac{-8\pm2\sqrt{5} }{2}$

$(2x+3)=-4\pm \sqrt{5}$

$(2x+3)=-4-\sqrt{5}$ or $(2x+3)=-4+ \sqrt{5}$

$2x=-3-4-\sqrt{5}$ or $2x=-3-4+ \sqrt{5}$

$2x=-7-\sqrt{5}$ or $2x=-7+ \sqrt{5}$

$x=\frac{-7-\sqrt{5}}{2}$ or $x=\frac{-7+ \sqrt{5}}{2}$

Function g can be thought of as a translation (shifted) version of f(x)=x^2

Natasha_Volkova [10]

Answer:

Step-by-step explanation:

f(x)=x^2 represents a parabola with vertex at (0, 0), that opens up.

If we translate this graph h units to the right, then g(x) will be:

g(x) = (x - h)^2.

If we translate the graph of f(x)=x^2 k units up, then g(x) will be:

f(x)=x^2 + k

Next time, please indicate whether you are shifting the original graph to the right or to the left, and/or up or down.
