<span>y in (-oo:+oo)

(3*y+6)/11 = -9 // + 9

(3*y+6)/11+9 = 0

(3*y+6)/11+(9*11)/11 = 0

3*y+9*11+6 = 0

3*y+105 = 0

(3*y+105)/11 = 0

(3*y+105)/11 = 0 // * 11

3*y+105 = 0

3*y+105 = 0 // - 105

3*y = -105 // : 3

y = -105/3

y = -35

y = -35</span>

(3y+6)/11=-9
times both sides by 11
3y+6=-99
minus 6 both sides
3y=-105
divide both sides by 3
y=-35

In 2007, the population of Ecuador was estimated at
swat32

Answer:

In 2012 , the population will be 15 million

Step-by-step explanation:

We start by setting up an exponential equation that defines the increase

P(t) = I(1 + r)^t

P(t) represents the present population = 15 million

I is the population in 2007 which is 13.8 million

r is 1.6% = 0.016

t is what we want to calculate

15 million = 13.8 million (1 + 0.016)^t

15/13.8 = (1.016)^t

1.09 = (1.016)^t

ln 1.09 = t ln 1.016

t = ln 1.09/ln 1.016

t = 5.429 which is approximately 5

So in 2007 + 5 = 2012, the population will be 15 million

A bicycle rider increases his speed from 5 m/s to 15 m/s in 10 seconds
valentina_108 [34]
To find the acceleration of the bicycle rider, we are going to use the acceleration formula: a= \frac{v_{f}-v_{i}}{t}
where
a is the acceleration 
v_{i} is the initial speed 
v_{f} is the final speed 
t is the time 

We know from our problem that increases his speed from 5 m/s to 15 m/s in 10 seconds, so his initial speed is 5 m/s and his final speed is 15 m/s; therefore, v_{i}=5, v_{f}=15, andt=10. Lets replace those values in our formula:
a= \frac{v_{f}-v_{i}}{t}
a= \frac{15-5}{10}
a= \frac{10}{10}
a=1

We can conclude that the acceleration of the bicycle rider 1 m/s^2
