Answer:
Step-by-step explanation:
<u>We know that:</u>
<u>Solution:</u>
- 30 kilometers = 1 hour
- => 30 x 21/2 kilometers = 21/2 hours
- => 15 x 21 kilometers = 21/2 hours
- => 315 kilometers = 21/2 hours
Hence, in 21/2 hours, the cyclist rides 315 kilometers.

Answer:
Step-by-step explanation:
To find the inverse, we want to switch the y with x and x with y. Once we do that, we solve for y.
[switch x and y]
[subtract both sides by 3]
[multiply both sides by 2]
Now, we know that .
The answer is -3^15
You start with the brackets and (3^2x3^3) =3^5. Now we have -(3^5) ^3. Because the is one expoente out of the brackets and one in you multiple the exponent (3x5=15) and you distribute the negative sign you get -3^15. Hope this helps!
