Answer:

No. The interval  (0, 4)  is not a reasonable solution because the left endpoint results in a fraction value for the function and there cannot be a fraction of a lightening bug.

Given:

The equation is:

3^x\times 9=3^{2n-1}

To find:

The value of n in terms of x.

Solution:

We have,

3^x\times 9=3^{2n-1}

It can be written as

3^x\times 3^2=3^{2n-1}

3^{x+2}=3^{2n-1}                [\because a^ma^n=a^{m+n}]

On comparing the exponents, we get

x+2=2n-1

Add 1 on both sides.

x+2+1=2n-1+1

x+3=2n

Divide both sides by 2.

\dfrac{x+3}{2}=n

Therefore, the value of n is terms of x is n=\dfrac{x+3}{2}.

Two cars leave a restaurant at the same time and travel along a straight highway in opposite directions.At the end of 3 hours, t
DENIUS [597]
The faster car would be traveling at 60 miles per hour and the slower car would be traveling at 40 miles per hour.

300÷3=100 so once you find how long they travel per hour. you need to divided they into equal parts. than you need them to be 20 apart(one is traveling 20 mi. faster than the other) if you give 10 to the other it leaves you with 60 and 40. Hope this helps and I didn't confuse you!

Y=-2x+2y=-2x-2what is the answer?
ale4655 [162]

We can follow the next step to find the solutions to this system of linear equations:

-2x+2=-2x-2\Rightarrow-2x+2x+2=-2x+2x-2=2\ne-2

Since we have the previous result ( 2 is different from -2), the system has no solutions.

Therefore, the system of line equations has no solutions.
