Equation 1)  y=x+3
Equation 2)  y=2x+5

Rearrange both equations so that (x) and (y) are on the same side.

1) -x+y=3
2) -2x+y=5

Subtract equations with each other.

x=-2

Plug in -2 for (x) in equation 1.

y=(-2)+3

Simplify.

y=1

(-2, 1)

Write an equation of the parabola in intercept form with x-intercepts of 12 and -6; and an axis of symmetry of (14, 4).
xenn [34]

Intercept form is: y = a(x - p)(x - q)  

It is given that:  p = 14, q = -6, x = 14, y = 4

4 = a(14 - 12)(14 - (-6))

4 = a(2)(20)

4 = 40a

\frac{4}{40} = \frac{40a}{40}

\frac{1}{10} = a

Answer: y = \frac{1}{10}(x - 14)(x + 6)

Cell phone companies estimate that the total number of text messages (t) since the beginning of the month can be modeled by t=40
GalinKa [24]

The desired number is the difference between the number of messages sent by the 16th day and the number sent by the 9th day:

... n = t(16) - t(9)

... n = (40×√16) - (40×√9)

... n = 40×(4 - 3) = 40


40 text messages were sent between the ninth and sixteenth day of the month.
