Rossi is upgrading his cell phone in monthly service plan. Triax offers a new phone for $50 and a limited service for a monthly

Margaret [11]

Answer:

5 months

Step-by-step explanation:

Let n be the number of months.

1. Triax offers a new phone for $50 and a limited service for a monthly fee of $40. Then the phone will cost

$50+$40·n.

2. Cellular offers a new phone and unlimited service for a monthly fee of $50. Then the phone will cost

$50·n.

Equate these to amounts:

50+40n=50n,

50=50n-40n,

50=10n,

10n=50,

n=50:10,

n=5.

$\frac{6.78}{6}$

Now, let's divide 6.78 in to 6 to find our unit price.

$\frac{1.13}{1}$

Now we know 1 pound, (our unit price), costs...

$$1.13$

Write a quadratic function for each graph described.

user100 [1]

Answer:

$y=2x^2-\frac{4}{3}x-\frac{10}{3}$

Step-by-step explanation:

we know that

The roots of the quadratic function (x-intercepts) are

x=-1 and x=5/3

we can write the equation of the parabola as

$y=a(x+1)(x-\frac{5}{3})$

where

a is a coefficient

Remember that

The parabola pass through the point (5,40)

substitute the value of x and the value of y of the ordered pair in the quadratic equation and solve for a

x=5, y=40

$40=a(5+1)(5-\frac{5}{3})$

$40=a(6)(\frac{10}{3})$

$40=20a\\a=2$

substitute

$y=2(x+1)(x-\frac{5}{3})$

apply distributive property

$y=2(x^2-\frac{5}{3}x+x-\frac{5}{3})\\\\y=2(x^2-\frac{2}{3}x-\frac{5}{3})\\\\y=2x^2-\frac{4}{3}x-\frac{10}{3}$
