Answer:

table two

Step-by-step explanation:

The increase rate for table one is constant that's why it is a linear function

In the second table, however, the increase rate increases as x increases, it is not constant; therefore, table two is a quadratic function.

Dash offers and unlimited talk and texting plan for $80 per month AB&C charges $0.20 per text message and $55 for 1,000 min

mr_godi [17]

Answer:

Let's define x as the number of text messages send.

y as the number of 1,000 minutes talk per month.

(so we can write y = N/1000) where N is exactly the number of minutes that you talked that month.

> The equation for Dash is:

C1(x, y) = $80

>The equation for AB&C

C2(x,y) = $0,20*x + $55*y

> Horizon

C3(x,y) = $0.10*x + $75*y.

Now, which company you should go for?

Well, it depends on the values of x and y that you have.

if in your case you have x > y, you may want to go with Horizon, because the price per text is smaller.

if you usually talk, you may want to go with AB&C because the slope for y is smaller.

If you send a lot of texts and talk a lot, then Dash is the best option, because there is no dependence with the variables x, y

Which two equations would be most appropriately solved by using the quadratic formula?

leva [86]

For this case we have that by definition, the quadratic formula is: $x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}$

A quadratic equation is of the form:

$ax ^ 2 + bx + c = 0$

Option A: This equation can be solved without the quadratic formula

$x ^ 2 = \frac {9} {3}\\x ^ 2 = 3\\x = \pm \sqrt {3}$

Option B:

This equation is not as easy to solve by factoring or as option A. We can use the quadratic formula.

Option C:

$-2x ^ 2 + 5x = 7$

Similarly, this equation can be solved with the quadratic formula

Option D:

$- (x - 3) (x + 9) = 0$

In this factored equation we can see that the roots are

$x_ {1} = 3\\x_ {2} = - 9$

Answer:

Option B, C
