Answer:

$u = -4$

Step-by-step explanation:

Solve for u.

$-11u = 44$

Divide both sides by -11

$\frac{-11u}{-11} = \frac{44}{-11}$

Now, simplify.

$\frac{-11u}{-11}: u$

$\frac{44}{-11}: -4$

There's your answer!

$u = -4$

If $-2 < x \le 3,$ then find all possible values of $5x + 1.$ Give your answer in interval notation.

Answer: $(-9, 16]$

This is the interval from -9 to 16. Exclude -9 but include 16.

=====================================================

Work Shown:

The idea is to multiply all sides by 5, then add 1 to all sides

$-2 < x \le 3$

$5(-2) < 5x \le 5(3)$

$-10 < 5x \le 15$

$-10+1 < 5x+1 \le 15+1$

$-9 < 5x+1 \le 16$

This converts to the interval notation $(-9, 16]$

note: a curved parenthesis means "do not include this value in the solution set"; while a square bracket has us include the value. So we exclude -9 and include 16.

City A grows by 5% every year. In 2021, it has a population of 145,201. What will the population be in 2037?

Diano4ka-milaya [45]

Answer:

About 316,955 people

Step-by-step explanation:

The population of this city can be modeled with the formula $P=I\cdot(1.05^t)$ , where P represents the current population, I represents the initial population, and t represents the amount of time in years since the start of the model. Plugging in 145,201 for I and (2037-2021)=16 for t, we get:
