You are choosing between two different cell phone plans. The first plan charges a rate of
shutvik [7]

If you talk for 384.23 minutes the two plans will have the same cost.

<h3>What is a system of equations?</h3>

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

x is the number of minutes that will be used during a month:

C₁ = 0.24x

C₂ = 49.95 + 0.11x

So, when 1st = 2nd

0.24x = 49.95 + 0.11x

0.24x - 0.11x = 49.95

0.13x = 49.95

x = 49.95/0.13

x = 384.23 minutes

Hence, If you talk for 384.23 minutes the two plans will have the same cost.

Lindsay is creating a bridge out of dried pasta and glue. In her plans, she sketches the graph to determine the lengths of the n
alexgriva [62]
From the graph shown it can be seen that the bridge is represented by a parabola with vertex of (5, 8) and roots of 1 and 9.

Recall that the vertex form of the equation of a parabola with vertex (h, k) is given by
y=a(x-h)^2+k

Thus, the equation of the given graph in vertex form is given by
y=a(x-5)^2+8

Also, recall that the equation of a parabola with roots, p and q, is given by
y=a(x-p)(x-q)

Thus the equation of the given graph can be given by
y=a(x-1)(x-9)

To get the value of a, we equate both equations and solve as follows:
a(x-5)^2+8=a(x-1)(x-9) \\  \\ a(x^2-10x+25)+8=a(x^2-10x+9) \\  \\ ax^2-10ax+25a+8=ax^2-10ax+9a \\  \\ 25a-9a=-8 \\  \\ 16a=-8 \\  \\ a=- \frac{8}{16} =- \frac{1}{2}

Therefore, the <span>function that Lindsay used to create her design is
f(x)=-0.5(x-5)^2+8
