Answer:
b = - 0.389
Step-by-step explanation:
38/99=b+17/22
to solve this expression we would make b the subject of the formulae
and evaluate the other parameters.
38/99=b+17/22
collect the like terms
38/99 - 17/22 = b
22( 38) - 99 (17)/ 2178 = b
836 - 1683/2178 = b
-847/2178 = b
b = - 0.389

Question:
Approximate log base b of x, log_b(x).
Of course x can't be negative, and b > 1.
Answer:
f(x) = (-1/x + 1) / (-1/b + 1)
Step-by-step explanation:
log(1) is zero for any base.
log is strictly increasing.
log_b(b) = 1
As x descends to zero, log(x) diverges to -infinity
Graph of f(x) = (-1/x + 1)/a is reminiscent of log(x), with f(1) = 0.
Find a such that f(b) = 1
1 = f(b) = (-1/b + 1)/a
a = (-1/b + 1)
Substitute for a:
f(x) = (-1/x + 1) / (-1/b + 1)
f(1) = 0
f(b) = (-1/b + 1) / (-1/b + 1) = 1
Answer:28
Step-by-step explanation:
If she can invite only 45 and 17 are family just subtract 45 from 17 which is 28 she can Invite 28 more people
1/3= .3333333
.3333333 x 5= 1.6666666
1.66666+ 7(5)= 1.66666 +35
36.666666
