Answer:
4x-105
Step-by-step explanation:
The answer is 4x-105 because you do cross multiply with (x+7)(x-3) and that answer is (2x-21) then you multiply (4x-21)(2x+5) and the overall answer is 4x-105.
15.20 would be the tip
Hope this helps :)
First graph the normal graph y = -x
Then since y is less than -x, shade the whole graph below the line.
Answer:
stars.
Step-by-step explanation:
We have been given that a particular galaxy has a total mass of
grams and the average star in that galaxy has a mass of
grams. We are asked to find the number of stats in the galaxy.
To find the number of stats in the given galaxy, we will divide total mass of galaxy by mass of an average star in the galaxy as:
![\text{The number of stats in the given galaxy}=\frac{10^{58}}{10^{34}}](https://tex.z-dn.net/?f=%5Ctext%7BThe%20number%20of%20stats%20in%20the%20given%20galaxy%7D%3D%5Cfrac%7B10%5E%7B58%7D%7D%7B10%5E%7B34%7D%7D)
Using exponent property
, we will get:
![\text{The number of stats in the given galaxy}=10^{58-34}\\\\\text{The number of stats in the given galaxy}=10^{24}\\\\\text{The number of stats in the given galaxy}=1000,000,000,000,000,000,000,000](https://tex.z-dn.net/?f=%5Ctext%7BThe%20number%20of%20stats%20in%20the%20given%20galaxy%7D%3D10%5E%7B58-34%7D%5C%5C%5C%5C%5Ctext%7BThe%20number%20of%20stats%20in%20the%20given%20galaxy%7D%3D10%5E%7B24%7D%5C%5C%5C%5C%5Ctext%7BThe%20number%20of%20stats%20in%20the%20given%20galaxy%7D%3D1000%2C000%2C000%2C000%2C000%2C000%2C000%2C000)
Therefore, there are approximately 1000,000,000,000,000,000,000,000 stars in the given galaxy.
