Answer:
The plans will cost the same when the amount you have to pay for talking for "x" minutes on Plan A is the same has what you have to pay for talking for the same number of "x" minutes when using Plan B.
$$ Plan A = $$ Plan B
To find the charge on each plan we add the base rate to the per minute call rate for each.
Plan A = $27 + $0.11x
Plan B = $13 + $0.15x
Let's drop the $ sign for now and get rid of the decimal point by multiplying by 100.
2700 + 11x = 1300 + 15x
Subtracting 11x and 1300 from both sides:
4x = 1400
x = 350 min.
Using this result the plans both cost $65.50 for 350 min of talk time.

Answer:
- y-intercept: (0, 3)
- axis of symmetry: x = -1
Step-by-step explanation:
The y-intercept is the constant, 3. It is the value of f(0).
__
The axis of symmetry of the quadratic function ...
f(x) = ax^2 +bx +c
is ...
x = -b/(2a)
Here, using that formula gives ...
x = -(2a)/(2(a)) = -1
The axis of symmetry is x = -1.

Hope it helps
I think -4
Because the form is y=ax + b
a is the slop so -4 is the answer.
