Answer:
520 dollars
Step-by-step explanation:
5 percent of 400 is 20, over 6 years you multiply 20 by 6 giving you 120. 400 plus 120 is 520
Answer:
y = e^x -4
Step-by-step explanation:
The function has increasing slope so is exponential, not logarithmic. That eliminates the first two choices. The horizontal asymptote is -4, so the function is shifted down 4 units (not 3). The appropriate choice is ...
y = e^x -4
At x=-3:
2x^2+ x
= 2(-3)^2+ (-3)
= 2*9 -3
= 18 -3
= 15
The value of 2x^2+ x is 15 if x=-3~

-

=

Since the two fractions have a common denominator already, we can just subtract the numerators.
b-3b=-2b or -3b+b=-2b
Either way you get the same answer :)
Our new fraction is

Now we know that this must be equal to

Again, since the denominators are already the same of course they are equal. 13=13
Now we have to set the numerators equal
-2b=8
Use inverse operations to get b alone
-2b=8
÷-2 ÷-2
b=-4
