What is the inverse of the function 9y - 6 = 3x ?

IgorC [24]

Answer:

Option (2)

Step-by-step explanation:

Given function is,

9y - 6 = 3x

y = $\frac{3x+6}{9}$

To find the inverse of the given function,

1). Substitute x in place of y and y in place of x.

x = $\frac{3y+6}{9}$

2). Now we have to solve this equation for the value of y.

9x = 3y + 6

3y = 9x - 6

y = (3x - 2)

Therefore, inverse of the given function is y = (3x - 2)

Option (2) will be the answer.

Henry has two pixie sticks full of delicious sugar. Henry loves to share. It just so happens that there are two other friends ne

Effectus [21]

Answer: 14.7 grams

Step-by-step explanation:

Given : Henry has two pixie sticks full of delicious sugar.

Each pixie stick has 22 grams of sugary goodness.

Then, Total sugary goodness in 2 pixie sticks= $2\times22=44\text{ grams}$

Total persons = 3 [Including himself]

If he divides 2 sticks evenly among 3 persons , then the amount of sugary goodness each persons will receive

= Total sugary goodness in 2 pixie sticks divided by 3

$=44\div3=14.6666666667\approx14.7$ grams

Hence, He will share 14.7 grams of sugary goodness with each of his friends.

The population of a city is modeled by the exponential function ƒ (x) = 689,254 · 2.40.014x, where x is the number of years af

Alex Ar [27]

Answer:

Step-by-step explanation:

Given the population of a city is modeled by the exponential function

ƒ (x) = 689,254 · 2.4e^0.014x, where x is the number of years after 2000

In order to determine the year that the city's population will exceed one million, we will substitute f(x) = 1,000,000 and find x first as shown:

1,000,000 = 689,254 2.4e^0.014x,

1000000/689,254 = 2.4e^0.014x,

1.4508 = 2.4e^0.014x,

1.4508 /2.4 = e^0.014x,

0.6045 = e^0.014x,

Apply ln to both sides

ln 0.6045 = lne^0.014x,

-0.5033 = 0.014x

x = -35.95

Since x cannot be negative, lets say x ≈ 36years

<em>This means that the population will exceed one million after about 36 years. The year it will exceed this amount will be 2000+36 = 2036</em>

<em>Note that the exponential equation used was not correctly written but the same calculation can be employed for any exponential functions you might have.</em>

write an equation to solve and find the answer to the following rate problem. a garden store sells six plants per hour how many

Virty [35]

Let x represent the number of plants that they will sell in five hours

We were told that the garden store sells six plants per hour. This means that

6 plants = 1 hour

then,

x plants = 5 hours

By cross multiplying, it becomes

x * 1 = 6 * 5

x = 30

They will sell 30 plants in 5 hoursx
