What is the graph of the solution to the following compound inequality?
ohaa [14]

Answer:

<h2>C.</h2>

Step-by-step explanation:

<, > - open circle

≤, ≥ - solid circle

<, ≤ - draw to the left

>, ≥ - draw to the right

3-x\geq2\qquad\text{subtract 3 from both sides}\\\\-x\geq-1\qquad\text{change the signs}\\\\\boxed{x\leq1}\\\\4x+2\geq10\qquad\text{subtract 2 from both sides}\\\\4x\geq8\qquad\text{divide both sides by 4}\\\\\boxed{x\geq2}

Karolina [17]

Answer:

wastewater and fertilizer runoff

Step-by-step explanation:

Factors such as temperature, pH electrochemical (redox) potential, and the transparency of air and water can affect the chemical and physical characteristics of ecological systems. This are as a result of activities like climate change, water contamination, and changes in water runoff.

Wastewater and fertilizer runoff causes low amount of dissolved oxygen  in water, which affect biological communities and cycling thereby resulting in chemical and physical states changes.

The total interest paid on a 3​-year loan at 9​% interest compounded monthly is ​$1505.82 determine the monthly payment for the
Kruka [31]
Number of compounding periods is
n=12months×3years=36
I assume that

The total interest=
monthly payment×number of compounding periods - the amount of the present value of an annuity ordinary
I=x×n-pv

Let monthly payment be X

I =Total interest is 1505.82

The present value of an annuity ordinary is
Pv=X [(1-(1+0.09/12)^(-36))÷(0.09/12)]

now plug those in the formula of the total interest above
I=x×n-pv
1505.72=36X-X [(1-(1+0.09/12)^(-36))÷(0.09/12)]
Solve for X using Google calculator to get the monthly payment which is
X=330.72

Check your answer using the interest formula
36×330.72−330.72×((1−(1+0.09
÷12)^(−12×3))÷(0.09÷12))
=1,505.83

Starting at home Omar traveled a pill to the gift store for 30 minutes such as 10 mph event travels back home along the same pat
Dmitry [639]

We know Distance formula is  Distance = speed * time

time = \frac{distance}{speed}

Let, the distance Omar traveled = d  and speed is 10 miles per hour

Time taken  t for the first trip  t = \frac{d}{10}

Let, the distance Omar traveled = d  and speed is 30 miles per hour

Time taken  t for the return  trip  t = \frac{d}{30}

Total time taken =  \frac{d}{10} + \frac{d}{30} = \frac{3d+d}{30} = \frac{4d}{30}

Now, Average \ speed = \frac{total \  distance}{total \ time \ taken}

Total distance = d+d= 2d

Average speed = \frac{2d}{\frac{4d}{30}} = 2d * \frac{30}{4d} = 15

His average speed for the entire trip from home to the gift store and back is

15 miles per hour
