-3 (x - 5) - 8 (y + 2) + (-3) (6 - 4b)

First, simplify your brackets. / Your problem should look like: -3 (x - 5) - 8 (y + 2) + -3 (6 - 4b)
Second, simplify. / Your problem should look like: -3 (x - 5) - 8 (y + 2) - 3 (b - 4b)
Third, expand your problem. / Your problem should look like: -3x + 15 - 8y - 16 - 18 + 12b
Fourth, simplify. / Your problem should look like: -3x - 8y + 12b - 19

Answer: -3x - 8y + 12b - 19 (D)

−3(x−5)−8(y+2)−3(6−4b)

Distribute:

=(−3)(x)+(−3)(−5)+(−8)(y)+(−8)(2)+(−3)(6)+(−3)(−4b)

=−3x+15+−8y+−16+−18+12b

Combine Like Terms:

=−3x+15+−8y+−16+−18+12b

=(12b)+(−3x)+(−8y)+(15+−16+−18)

=12b+−3x+−8y+−19

In the year 2000, the population of a city was 600,000 citizens. The population increases at a rate of 1.8% per year.
dem82 [27]

Answer:

a) 600,000 (1.018)ᵗ, the graph is below:

* "t" is the years. 2000 is the first year, so "t" would be 1. 2012 is the 12th year so "t" would be 12.

b) As the years go by, the population increases. The years (X), and population (Y) both increase together. The graph shows that when the years increase the population increases.

c) In 2012, which would be 12 years later, I predict the population would be around 743,232 people.

At the youth center, the committee has decided to create a circular shaped flower bed. They plan to cover the flower bed with mu
FrozenT [24]

Answer:

12 in diameter bed will  give better value

Step-by-step explanation:

Given:

Cost of cover 12 in diameter bed = $150

Cost of cover 18 in diameter bed = $300

Find:

Better value

Computation:

Area of bed = πr²

Area of 12 diameter of bed = (22/7)(6)²

Area of 12 diameter of bed = 113.14 in²

Area of 18 diameter of bed = (22/7)(9)²

Area of 18 diameter of bed = 113.14 in²

Area of 18 diameter of bed = 254.57 in²

Compare cost of bed 1 = 113.14 / 150 = 0.75 in per dollar

Compare cost of bed 2 = 254.57 / 300 = 0.84 in per dollar

So,

12 in diameter bed will  give better value

What are three equivalent expressions for 3x+3(x+y)
Cloud [144]

3 x + 3 (x + y)

3 (2 x + y)

6 x + 3 y

y = -2 x

y = -2 x (3 (x + y) + 3 x) = 6

(3 (x + y) + 3 x) = 3

(3 x + 3 (x + y)) dx = 3 (x^2 + x y) +

(x^2 + y^2<R^2)(3 (x + y) + 3 x) dx dy = 0

(3 x + 3 (x + y)) dy dx = 0

Step-by-step explanation:

Hope this helps ツ
