Answer:
Assuming you're solving for <em>n</em>, 1. n=-1 2. n=-1.6
Step-by-step explanation:
1. -5(2-5n)+6=-5n-34-2
Distributive Property
-10+25n+6=-5n-32-2
Add Like Terms
-4+25n=-5n-34
Subtract -4
25n=-5n-30
Subtract -5n
30n=-30
Divide by 30
n=-1
2. -5(2-5n)+6=-5n-34-20
Distributive Property
-10+25n+6=-5n-32-20
Add Like Terms
-4+25n=-5n-52
Subtract -4
25n=-5n-48
Subtract -5n
30n=-48
Divide by 30
n=-1.6
For 11a its 2:10 because how you would come up with it is by placing pablos free minutes first and then putting pablos paid minutes and 11b is8:25 because once again you would place sams free minutes first and then his paid minutes
I would make a table and plug in values for "x" in the equation to find f(x) or y
x = 0
(there is a rule that when the exponent is 0, the result is 1)
f(0) = 2 (0,2)
x = 1
f(1) = 6 (1,6)
You could do more points.
But these two points shows that the y-intercept (the y value when x = 0 or (0,y)) is 2, and that the graph is increasing.
Your answer is B
Are you trying to find what X AND Y equal or just X/Y?
