Answer:
what does d equal?
Step-by-step explanation:
6 is the answer 18 divided by 3 equals to 6 so that’s the answer
Substitute 8 for x in the function.
y=50(8)=400
He would travel 400 miles
When you are multiplying an exponent directly into a number/variable with an exponent, you multiply the exponents together.
For example:
![(x^{2} )^{3} = x^6](https://tex.z-dn.net/?f=%28x%5E%7B2%7D%20%29%5E%7B3%7D%20%3D%20x%5E6)
![(x^{3} )^5=x^{15}](https://tex.z-dn.net/?f=%28x%5E%7B3%7D%20%29%5E5%3Dx%5E%7B15%7D)
When you are multiplying a variable with an exponent by another variable with an exponent, you add the exponents together.
For example:
![(x^{2} )(x^{3})=x^{5}](https://tex.z-dn.net/?f=%28x%5E%7B2%7D%20%29%28x%5E%7B3%7D%29%3Dx%5E%7B5%7D)
![(x^{1} )(x^{2})=x^{3}](https://tex.z-dn.net/?f=%28x%5E%7B1%7D%20%29%28x%5E%7B2%7D%29%3Dx%5E%7B3%7D)
![(\frac{(x^{-3})(y^{2})}{(x^{4})(y^{6})} )^{3}=\frac{(x^{-9})(y^{6})}{(x^{12})(y^{18})}](https://tex.z-dn.net/?f=%28%5Cfrac%7B%28x%5E%7B-3%7D%29%28y%5E%7B2%7D%29%7D%7B%28x%5E%7B4%7D%29%28y%5E%7B6%7D%29%7D%20%29%5E%7B3%7D%3D%5Cfrac%7B%28x%5E%7B-9%7D%29%28y%5E%7B6%7D%29%7D%7B%28x%5E%7B12%7D%29%28y%5E%7B18%7D%29%7D)
You multiply 3 into each exponent in the numerator and the denominator
![\frac{(x^{-9})(y^{6})}{(x^{12})(y^{18})}= \frac{y^{6}}{(x^{9})(x^{12})(y^{18})}](https://tex.z-dn.net/?f=%5Cfrac%7B%28x%5E%7B-9%7D%29%28y%5E%7B6%7D%29%7D%7B%28x%5E%7B12%7D%29%28y%5E%7B18%7D%29%7D%3D%20%5Cfrac%7By%5E%7B6%7D%7D%7B%28x%5E%7B9%7D%29%28x%5E%7B12%7D%29%28y%5E%7B18%7D%29%7D)
When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.
![\frac{y^{6}}{(x^{21})(y^{18})} = \frac{1}{(x^{21})(y^{12})}](https://tex.z-dn.net/?f=%5Cfrac%7By%5E%7B6%7D%7D%7B%28x%5E%7B21%7D%29%28y%5E%7B18%7D%29%7D%20%3D%20%5Cfrac%7B1%7D%7B%28x%5E%7B21%7D%29%28y%5E%7B12%7D%29%7D)
When you have something like this:
![\frac{x^{2}}{x^5}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B2%7D%7D%7Bx%5E5%7D)
You subtract the exponents together, so:
![\frac{x^2}{x^5} = x^{2-5} = x^{-3} = \frac{1}{x^3}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E2%7D%7Bx%5E5%7D%20%3D%20x%5E%7B2-5%7D%20%3D%20x%5E%7B-3%7D%20%3D%20%5Cfrac%7B1%7D%7Bx%5E3%7D)
Your answer is the second option
