answerrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr
The complete question in the attached figure
let
r-----------> <span>the amount charged for a refill
</span><span>b ----------> the amount charged for the egg breakfast.
we know that
2r+b=8.40
3r+b=9.35
Part a) </span><span>Write a system of equations for the situation
the answer Part a) is</span>
2r+b=8.403r+b=9.35<span>
Part b) </span><span>Graph the equations in the system
</span>
using a graph tool
see the attached figure
Part c) <span>Use your graph to estimate how much each item cost.
we know that
</span><span>the point of intersection of both graphs is the solution of the system
</span>
the solution is the point (0.95,6.5)
therefore
r=0.95
b=6.5
the amount charged for a refill is $0.95 the amount charged for the egg breakfast is $6.5
Answer:
M= -3/4

Thanks for letting me answer your question! If you have any more questions feel free to ask me! Have a nice day and please consider making me Brainliest!
Please, use " ^ " to denote exponentiation: p(t) = t^2 + 5t + 6.
To find the critical points, differentiate p(t) with respect to t, set the result = to 0, and then solve the resulting equation for t:
p '(t) = 2t + 5 = 0
Solving for t: 2t = -5, and so t = -5/2. (-5/2, p(-5/2)) is the critical point. That evaluates to (-5/2, -0.25). This happens to be the vertex of a parabola that opens up.
