Answer:
x=1
y=8.6

Explanation:

first start by assigning a random value to a random variable, let’s say x=1

from there the equation becomes solveable

9x1+-5y=-34
simplify
9-5y=-34
-9 from both sides
-5y=-43
divide both sides by-5
y=8.6

hope this helps :)

Cuatro meses después que se detuviera la publicidad, una compañia fabricante notifica que sus ventas han cai­do de 100.000 unida
Volgvan

Answer:

51,200 unidades

Step-by-step explanation:

Paso 1

Calculamos el porcentaje de disminución

= 100000 - 80000/100000 × 100

= 20000/100000 × 100

= 20%

Por lo tanto, el porcentaje de disminución cada mes = 20%

Paso 2

La fórmula de la disminución exponencial

y = a (1 - r) ^ t

a = 80.000

r = 20% = 0,2

t = tiempo en meses = 2

y = 80000 (1 - 0,2) ^ 2

y = 51.200 unidades

I don’t know the answer to that one can you help me please
dybincka [34]

Answer:

16/45

Step-by-step explanation:

Step 1:  When dividing fractions, use “KFC”.  It means Keep the first fraction, Flip the second one, and  

              Change it to multiplication

-4/20 ÷ -9/16    →    -4/20 ∙ 16/-9

Step 2:  Reduce any fractions if necessary, it makes multiplying them easier and you will have to reduce anyway at the end.  It’s easier arithmetic to reduce at this step.  The first fraction reduces because both the numerator and denominator are divisible by 4.  

-1/5  ∙   16/-9    

Step 3:  Multiply numerators and denominators together to get one fraction

(-16)/(-45)  

Step 4:  Cancel out the negatives, a negative divided by a negative is a positive.  Our final answer is

 

16/45
