Find the roots of the parabola given by the following equation <br> 2x^2+5X-9=2x

natta225 [31]

Answer:

$x=-3\:or\:x=\frac{3}{2}$

Step-by-step explanation:

The given parabola has equation

$2x^2+5x-9=2x$

We rewrite in standard form to obtain:

$2x^2+5x-2x-9=0$

$2x^2+3x-9=0$

Split the middle terms to get:

$2x^2+6x-3x-9=0$

Factor by grouping:

$2x(x+3)-3(x+3)=0$

$(x+3)(2x-3)=0$

$x=-3\:or\:x=\frac{3}{2}$

If 2^(x+3) - 2x = k(2^x) what is the value of k

svlad2 [7]

Answer:

$\large\boxed{C)\ 7}$

Step-by-step explanation:

Use:

$a^n\cdot a^m=a^{n+m}$

$2^{x+3}-2^x=2^x\cdot2^3-2^x=8\cdot2^x-2^x=(8-1)\cdot2^x=7\cdot2^x\\\\2^{x+3}-2^x=k(2^x)\\\\7\cdot2^x=k(2^x)\Rightarrow k=7$

$8\cdot2^x-2^x=8\cdot2^x-1\cdot2^x=(8-1)(2^x)=7\cdot2^x\\\\\text{distributive property:}\ a(b-c)=ab-ac$
