Answer:

2nd one

Step-by-step explanation:

x(2) + 2 = 420

you can use trial and error

210(2) = 420 but we need to add the two so lower the 120

209(2) = 418 418 + 2 = 420

using data from 2010 and projected to 2020, the population of the United Kingdom (y, in millions) can be approximated by the equ

natita [175]

Answer:

The projected population in 2026 is of 699.3 million.

Step-by-step explanation:

Population:

The population, in x years after 2000, is given by the follwing equation:

$y - 4.55x = 581$

That is:

$y(x) = 4.55x + 581$

What is projected population in 2026?

2026 - 2000 = 26, so this is y(26).

$y(26) = 4.55(26) + 581 = 699.3$

The projected population in 2026 is of 699.3 million.

Ronald is making hats and scarves for charity. He has enough yarn to make 5 hats and 8 scarves. Takes him 12 hrs to knit a hat,

kari74 [83]

Constraints are simply the subjects of an objective function.

The inequality that represents the constraint is: $12x + 6y \le 20$

Represent the number of hats with x, and the number of scarves with y.

From the question, we have:

He spends 12 hours to knit a hat
He spends 6 hours to knit a scarf

So, the equation of the total time spent is:

$Time = 12x + 6y$

This time spent is not more than 20 hours.

So, the inequality is

$12x + 6y \le 20$

Hence, the inequality that represents the constraint is: $12x + 6y \le 20$
