It  looks like they're multiplied, then you can simply add the exponents,

b⁸ * b⁴ = b⁸⁺⁴ = b¹²

remember, b⁸=b*b*b*b*b*b*b*b and b⁴=b*b*b*b

so b⁸ * b⁴ = b*b*b*b*b*b*b*b * b*b*b*b = b¹²

A phone company offers two monthly plans. Plan A is $26 plus and additional $.07 for each minute of calls. Plan B is $17 plus $.
finlep [7]
Ok, so the starting numbers are the fixed amounts. If we think of a graph, this is the y-intercept/ starting point and the rate would continue from there. This conclusion is very important to writing a linear equation in slope-intercept form.

If you don’t remember, slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.

First, let’s make our equations.....

Plan A: y = 0.07x + 26
Plan B: y = 0.12x + 17

Now since it is not stated, I’m not sure if you need to find where the cost of both plans is equal, but that would be found by setting up a system of equations and using substitution.

y = 0.07x + 26
y = 0.12x + 17

Substitute one equation into the other...

0.07x + 26 = 0.12x + 17
- 0.05x = -9
0.05x = 9
x = 180

And there you have it! After 180 minutes [3 hours] of talking, both phone plans will have the same cost.

The answers to (a)-(d) work is not needed just answers
Debora [2.8K]
A)  n(a) = 25 + 15 = 40
b) n(b) = 42+15 =57
c) n (a U b) = 25 +15+ 42 = 82 
d) n (a') = 42
e) n(b') = 25
f)  n(a intersection b)' =  82-15 = 67 
g) n (a U b)' =     14 
h)  n (a'  intersection  b') =  14
i)  n (a' U b') = 42 + 25 +14 = 81 


hope i helped a bit .. :-)
