#16: Let's clear the fraction on the way to solving this inequality for x. By mult. the given inequality by 2, we'll get -2 (is greater than) x+4. We want x to be positive. So, leave it where it is. Subtract 4 from both sides of this inequality. We end up with -6 (is greater than) x, which is the same thing as x (is less than) -6. What would the graph of that simple inequality look like?

Graph it. (Hint: The graph is a straight dashed line, and you must shade one side of it, but not the other side.

Answer:

Q(-10) = 299

Step-by-step explanation:

$Q(x) = 3x^{2} - 1$ $Q(-10) = 3(-10)^{2} - 1$

$Q(-10) = 3(100) - 1$ (-10 to the second power is 100 (negative times a negative equals a positive)

$Q(-10) = 300 - 1$ 3 times 100 equal 300

$Q(-10) = 299$

A father decided to give twenty five percent of his monthly income to his three children as their monthly allowance. The eldest

Helen [10]

Answer:

The youngest child will receive $2000

Step-by-step explanation:

A father decided to give 25% of his monthly income to his three children as their monthly allowance.

The eldest child got 45% of the allowance and the youngest got 20%. This means that the second child got:

100 - (45 + 20) = 100 - 65 = 35%

The second child received $3500.

Let the 25% of his monthly income be x.

Hence:

35% of x = 3500

=> $\frac{35}{100} * x = 3500$

$x = \frac{3500 * 100}{35}$

x = $10000

The amount the man shared among his children is $10000.

Hence, the youngest child (20%) will receive:

20% of $10000

$\frac{20}{100} * 10000$

= $2000

The youngest child will receive $2000.

On the first day of spring, an entire field of flowering trees blossoms. The population of locusts consuming these flowers rapid

Dima020 [189]

Answer:

$L(t) = 4600\bigg(\dfrac{6}{7}\bigg)^{\frac{t}{2.4}}$

Step-by-step explanation:

We are given the following in the question:

Number of locusts on first day = 4600

Gain in locust population every 2.4 days =

$\dfrac{6}{7}$

Thus, we can write the following function to model locust population in t days.

$L(t) = 4600\bigg(\dfrac{6}{7}\bigg)^{\frac{t}{2.4}}$

is the required function.

L(t) is a dependent function on t, L(t) is locusts population and t is amount of time in days.
