Answer:
Step-by-step explanation:
How does y change as x increases over a range?
As x increases from -6 to -4, y decreases from 0 to -7
It is a decreasing function in this range and for ranges less than x = -6 as well as the slope is nearly constant
As x increases from -4 to 0, y increases from -7 to 4
It is an increasing function in this range.
For x increasing from zero, y becomes less and less
It is a decreasing function in the range larger than x = 0
<span>We have this equation:
</span>
and we need to find the value of x.
First of all, we multiply the whole equation for 1/2, so our goal is to isolate x, therefore:
Next step we must do is to apply <span>logarithms:
</span>
Next, we have to apply identities and then to solve the equation:
Finally, we have the value of x which was our goal. This is the answer for the question above:
Answer:
2.38 lb bag = 4.99/lb 5.08 lb bag = 5.21/lb The 2.38 is the better buy
Step-by-step explanation:
11.88/2.38 = 4.99
26.47/5.08 = 5.21
4.99 is cheaper than 5.21 so the 2.38 lb bag is better buy
The answer is y-4=-3(x-13)
