Answer:

Hi there!

Your answer is;

1) x= 13

2) x= 5

Step-by-step explanation:

x-5 = 8

3x+2= 17

x-5=8

+5

x= 13

3x+2 = 17

-2

3x= 15

/3

x= 5

Hope this helps

15,000 blue trout were released into the Meherrin River for a scientific study. The function, f(x) = 15,000 (9/8)^x represents t
Ainat [17]
I'm guessing you mean f(x)=15,000(9/8)^x. If this is what you mean, the population would increase by about 12,000 (12030.4870605 to be exact).
Step-by-step explanation:
Starting equation: f(x)=15,000(9/8)^x
You can clean up the 9/8 to be 1.125
Now what you want to do is find the answer to (9/8)^5 which is 1.8020324707
Next multiply 1.8020324707 by 15,000 and you get 27030.4870605
Finally 27,030.4870605 - 15,000 gives you 12030.4870605. Which means that the population increased by about 12,000.

Solve. (x + 3)^1/2– 1 = x
Natali [406]

Answer:

x=1

Step-by-step explanation:

(x + 3) ^{ \frac{1}{2} }  - 1 = x  \\  \sqrt{x  + 3}   - 1 = x \\  \sqrt{x + 3}  = x + 1 \\ square \: both \: sides \\ x + 3 =  {x}^{2}  + 2x + 1 \\  {x}^{2}  + 2x - x + 1 - 3 = 0  \\  {x}^{2}  + x - 2 = 0  \\ x ^{2}  + 2x - x - 2 = 0  \\ (x^{2}  + 2x) - (x  + 2) = 0 \\ x(x + 2) - 1( x + 2) = 0 \\ (x - 1)(x + 2) = 0 \\ x - 1 = 0 \\ x = 1 \\  \\  \\ x  +  2 = 0 \\ x =  - 2

#82 will give brainliest to best answer!​
Fofino [41]

Answer:

\frac{6}{k-6}

Step-by-step explanation:

First, we can factor all of the following equations to turn that weird, huge looking thing into \frac{(k+6)(k-6)}{(k-6)(k-10)} ÷ \frac{(k-6)^2}{k(k-6)} × \frac{6(k-10)}{k(k + 6)}. We know that division is simply multiplication by the reciprocal, so that whole equation will turn into \frac{(k+6)(k-6)}{(k-6)(k-10)} × \frac{k(k-6)}{(k-6)^2} × \frac{6(k-10)}{k(k+6)}. Now we can cancel out some values if they are both in the numerator and denominator, which will turn that still huge looking thing into \frac{6}{k-6} which is our final answer, as it cannot be simplified further.

Hope this helped! :)

I don´t understand this: Lin’s father is paying for a $20 meal. a) He has a 15%-off coupon for the meal. How much is the discoun
Naddika [18.5K]

You'll have to set this up as two separate problems. First, we want to take 15% off the original $20 bill. To do this, you're going to multiply 20 by .15, which gives you $3. So, 15% off $20 is $17.

Now, we want to find 7% of the new bill, so we're going to multiply 17 by .07 to get $1.19, and add it to the $17, making the final bill $18.19. You could also multiply $17 by 1.07 to get your final total without the extra step in the middle, but only do that once you're comfortable with the math.

Which of the following graphs represents exponential decay?
charle [14.2K]

Answer:

C

Step-by-step explanation:

C is the only viable answer, because it it the only one that decreases as x approaches infinity. Exponential decay decreases, hence the decay part.
