290 - 200 = 3x

90 = 3x

90/3 = x

Eddie lives 3 times as far as Andy.Which exponential expression represents how far Eddie lives from the library?

A.3 the the 5th power miles

B.4 to the 3rd power miles

C.3 to the 4th power miles

D.3 to the 3rd power miles

Answers

Answer:

Step-by-step explanation:

3 times 3 =9 and is 3 by the 2nd power. Then that times three is 27 which is 3 to the third power. Now it’s time to find out where Eddie is compared to the library. Then that times 3 is 3 to the fourth power. So that’s how far Eddie is. He is 81 miles away.

the equation is 7x-3 over 9 > 8-2x

Answers

Answer:

solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]

The graph is attached below.

Option C is correct option.

Step-by-step explanation:

We need to solve the inequality [tex]\frac{7x-3}{9}\geq 8-2x[/tex]

First we will solve the inequality to find value of x

Solving:

[tex]\frac{7x-3}{9}\geq 8-2x[/tex]

Step 1: Multiply both sides by 9

[tex]9(\frac{7x-3}{9})\geq 9(8-2x)\\7x-3\geq 72-18x[/tex]

Step 2: Adding 3 on both sides

[tex]7x-3+3\geq 72-18x+3\\7x\geq 75x-18x[/tex]

Step 3: Add 18x on both sides

[tex]7x+18x\geq 75-+18x\\25x\geq 75[/tex]

Step 4: Divide both sides by 25

[tex]\frac{25x}{25}\geq \frac{75}{25}\\x\geq 3[/tex]

So, solving the inequality we get [tex]\mathbf{x\geq 3}[/tex]

The graph is attached below.

Option C is correct option.

Cells used a molecule called what to store and release energy The Gulf of Mexico dead zone that forms each summer at the mouth of the Mississippi River is caused largely by the input of agricultural fertilizers that stimulate phytoplankton blooms, which die, and are subsequently consumed through bacterial decomposition. Decomposition consumes oxygen, leading to very low dissolved oxygen levels and subsequent death or emigration (i.e. leaving the area) of fish and other marine life. Many scientists advocate creating wetlands (as well as restoring them) as a strategy to reduce the severity and extent of the dead zone. The idea is that the plants in the wetlands will remove these nutrients from the water (during growth) and prevent their washing into the river and the Gulf of Mexico.
