Answer:
-5
Step-by-step explanation:
Using rules of exponents we can change this equation to
y ^ (-9 * b) = y^45
-9*b = 45
b = -5
4 thousands equals 40 hundreds.
Xintercept is where the line crosses the x axis or where y=0
yintercept is where the line crosses the y axis or where x=0
aka
finding the finding the x intercept is finding the x value when y=0
finding the finding the y intercept is finding the y value when x=0
y=-1/2x-5
xint
y=0
0=-1/2x-5
5=-1/2x
-10=x
(-10,0) is x intercpet
yint
set x=0
y=-1/2(0)=5
y=-5
(0,-5) is yint
xint: x=-10 or at point (-10,0)
yint: y=-5, or at point (0,-5)
Answer:
????? what?
Step-by-step explanation:
Step-by-step explanation:
The derivative of log is

You can easily derive this using the Change of base rule, and natural log rules

Next, we differentiate with respect to x.


So back to the topic at hand,.
a=7, so we get

We plug in 0, we would get undefined
