Choose the correct symbol for interval notation when a value is to be included in the solution
A. Parenthesis
ex
you had
x3 when x=8
it will be
(8)3
For this case what you should know is that both functions are of the potential type.
We have then that
y = 2 * 2 ^ x This function grows exponentially upwards.
y = -2 * 5 ^ x This function grows exponentially downwards.
Answer See attached graphics.
<span>-3(5+8r)=33-8r
-15 - 24r = 33 - 8r
-15 - 33 = - 8r + 24r
-48 = 16r
-48/16 = r
-3 = r
r = -3</span>
It depends on what level of classes you take, but algebra classes in college do tend to be harder than algebra classes in high school or middle school.
