X = 4
-26 = -8x + 6
-32 = -8x
4 = x
Since that f is continuous for all x in R, and f > 0 then
for hence the asymptote is
y = 4
1pound is 800/560......which is 80/56-->10/7
so 1 pound is 10/7 dollars....
because you don't say for one dollar it is this many pounds.
also for unit rate i divide by 560 on both sides to get one pound on one side and then how many dollars on the other
Answer:
0<=x<10 or [1,10)
Step-by-step explanation:
You need to solve this using logarithms. I will use natural logarithms (LN on your calculator)
15,000 is the initial price of the car because 0.88^0=1.
All we need is 0.88^x>0.1
Remember that the logarithm of a^b is b*LN(a).
x*LN(0.88)>LN(0.1)
x<LN(0.1)/LN(0.88)
The relation changes from > to < because we are dividing by LN(0.88) which is negative.
The calculator now yields
LN(0.1)/LN(0.88)=10
So, x<10 years. But you buy the car at x=0, hence the relevant domain is.
0<=x<10 or [1,10)
I'm assuming there is supposed to be a x next to the -9. If that is the case, the inverse is:
f(x) = (x - 8)/-9
You can find this by switching the x and f(x) values and then solving for the new f(x) value.
<span>x=-9f(x)+8 ---> subtract 8 from both sides
</span>x - 8 = 9f(x) ----> divide both by -9
(x - 8)/-9 = f(x)
