h(3)=-6

Step-by-step explanation:

sub 3 into all the positions which variable X is present

h(3) =( 2 \times 4) - (4 \times 2) - 2(3)

h(3) = 8 - 8 - 6

h(3) =  - 6

1 If the population of a town increases by 280 people per year, then the growth is LINEAR (or constant). If the population in 20
Stella [2.4K]

The population in the year 2023 is 120,780.

The growth is linear hence, the equation of the growth is
y=ax+b where b represents the initial population and a is the number of people growing yearly.

So, according to the question statement, we have that

y=280x+b where x is the number of years past and y is the population in the xth year.

According to the given problem population in 2022 will be 120,500.

Suppose that the initial population is taken at 2000.

Hence, 120,500=280×(2022-2000)+b

⇒b=120,500-280×22

⇒b=120,500-6,160

    =114,340

So, the Linear equation becomes

y=280x+114,340

⇒y=280×(2023-2000)+114,340

⇒y=120,780

Hence, the population in the year 2023 is 120,780.

5(x + 3) + 9 = 3 (x - 2) + 6<br><br> Please Show Work.
snow_lady [41]

5(x + 3) + 9 = 3 (x - 2) + 6

5x + 15 + 9 = 3x - 6 + 6

5x + 24 = 3x

5x - 3x = -24

2x = -24

x = -24/2

x = - 12
