3^x-3^(x-2)=A*3^x <br><br> solve for A
ale4655 [162]

Answer:

a=\frac{8}{9}

Step-by-step explanation:

3^x-3x^{x-2} =a3^x

Divide both sides by 3^x:

3^{x-x}-3^{x-x-2}=a

Simplify:

3^0-3^{-2}=a\\a=1-\frac{1}{9} \\a=\frac{8}{9}

-9x-6y=15,9x-10y=145
vazorg [7]

-9x-6y=15

9x-10y=145

Find y first by eliminating the x.

Add the two equations together.

-9x+9x-6y+-10y=15+145

-6y+-10y=15+145

-6y-10y=160

-16y=160

divide both sides by -16 to get +y

-16y/-16=160/-16

y=-10

Use the substitution method to find x

-9x-6y=15

-9x-6(-10)=15

Do the bracket first

-9x+60=15

Move +60 to the other side. Sign changes from +60 to -60.

-9x+60-60=15-60

-9x=-45

Divide both sides by -9

-9x/-9=-45/-9

x=5

Answer:

( 5,-10)
