The answer is 9 because
5x+1+3x+3=20
x=2
3(2)+3
9
Answer:
you need 100ml of 5X TAE and 400ml of water.
Step-by-step explanation:
You need to use a rule of three:
where:
and
Therefore:
Then just rest the TAE volume to the final Volume and you get the amount of water that you need to reduce the concentration.
In the interval where the function is decreasingcreasing, the input or x values increase as the output or y values decrease. Looking at the graph, moving from the left to the right, the values of x are increasing whie the values of y are decreasing. This trend continued till we got to x = 0.5. Thus, in the interval from negative infinity to x = - 0.5, the function was decreasing.
The correct option is C
It is: c⁹d⁻⁷ / c¹⁴d⁻¹⁰
= c⁹⁻¹⁴ d⁻⁷⁺¹⁰
= c⁻⁵d³
In short, Your Answer would be c⁻⁵d³
Hope this helps!
