Answer:

Step-by-step explanation:

You can try substitution of x and check y- values.

1) f(x)= x - 4, f(-3) = -3-4= -7 wrong

2)f(x)= x + 4, f(-3) = -3 + 4 = 1 true

3) f(x) = 4x , f(-3) = 4*(-3)= - 12 wrong

4)f(x) = -4 - x = -4 - (-3)= -1 wrong

So, we already have only one correct answer, B.

DochEvi [55]

Answer:

Step-by-step explanation:

$a_{n}=a_{1}r^{n-1}\\0=848(0.75)^{n-1}\\or~(0.75)^{n-1}=0\\0.75$

$or~n \rightarrow 1+\infty\\or~n \rightarrow \infty$

Hence lake will never be free of pesticide.

The statements that apply to the ratio of rice and water are:

The ratio of rice to water is 1 to 2.5
The ratio of water to rice is 2.5 to 1

<h3>Ratios</h3>

Ratios are used to compare quantities of different measurements

The entries on the table are given as:

<u>Rice Water</u>

2 5

3 7.5

5 12.5

8 20

<h3>The ratios of both quantities</h3>

The ratio (r) of rice and water is then calculated as:

$r = \frac{Water}{Rice}$

Pick any corresponding table entry.

So, we have:

$r = \frac{5}{2}$

Divide

$r = 2.5$

This means that, the ratio of rice to water is 1 to 2.5, and the ratio of water to rice is 2.5 to 1
