9) A basic cell phone plan at Verizon Wireless costs $45 a month with an additional $0.10 per text message sent. AT&T charges $30 a month with an additional $0.13 per text message sent. How many text messages would you have to send for the plans to cost the same? If you send an average of 1200 text messages a month, which company would you want to choose as your provider?
a. Define your variables &Write your system of equations
b. Use your equations to solve. Make sure you label your answer

Answers

Number of tests made =x

Verzon C(x) = 45 + 0.1x => 45+0.1*1200 =165

AT & T C(y) = 30 + 0.13x=> 30 + 0.13*1200=186

For 1200 texts C(x) is less than C(y)

If the costs are to be the same then

45 + 0.1x = 30 + 0.13x

15=0.03x

15/0.03= x

Two different buses start their routes at the same corner at 9 A.M. Buses from one route stop at the library every 9 minutes. Buses from the other route stop at the library every 12 minutes. In what number of minutes will both buses end up at the library?

Answers

Answer: In 36 minutes both buses  will end up at the library.

Step-by-step explanation:

Given: Buses from one route stop at the library every 9 minutes.

Buses from the other route stop at the library every 12 minutes.

The number of minutes in which both buses will end up at the library= LCM(9,12)

Now , 9= 3 x 3

12= 2 x 2 x 3

LCM(9,12) = 2 x 2 x 3 x 3 = 36

In 36 minutes both buses  will end up at the library.

Find (f-g) (x)

Answers

Answer:

After solving we get [tex]\mathbf{(f-g)(x)=-4x^3+7x^2+5x-8}[/tex]

Option A is correct option.

Step-by-step explanation:

We are given :

[tex]f(x) = 4x^2 +5x -3\\g(x)= 4x^3 - 3x^2 +5[/tex]

We need to find (f-g)(x)

(f-g)(x) is equal to  f(x)-g(x)

So, finding (f-g)(x)

[tex](f-g)(x)=f(x)-g(x)\\(f-g)(x)=4x^2+5x-3-(4x^3-3x^2+5)\\(f-g)(x)=4x^2+5x-3-4x^3+3x^2-5\\Combining \ like \ terms:\\(f-g)(x)=-4x^3+3x^2+4x^2+5x-3-5\\(f-g)(x)=-4x^3+7x^2+5x-8[/tex]

So, after solving we get [tex]\mathbf{(f-g)(x)=-4x^3+7x^2+5x-8}[/tex]

The range of lengths the third piece of wood would be  3 < x < 37 .

Using triangle inequality theorems,  which states that the sum of two side lengths of a triangle is always greater than the third side.

Therefore,

A triangle with sides x, y  and z will be as follows;

x + y > z

x + z > y

y + z > x

Therefore, for the woods to form a triangular piece. The third length will be in the range 4 inches to 36 inches.  

Let's text the rules for the end points

20 inches + 17 inches > 4 inches

20 inches + 4 inches  > 17 inches

17 inches + 4 inches > 20 inches

20 inches + 17 inches > 36 inches

20 inches + 36 inches > 17 inches

17 inches + 36 inches > 20 inches

Therefore, the range of length for the third piece of wood  would be

Answer:

  1. line b is perpendicular to the other two, which are parallel

  2. line a is perpendicular to the other two, which are parallel

Step-by-step explanation:

1. The differences between coordinates (∆x, ∆y) are ...

  (-2, 3) -(1, -1) = (-3, 4) . . . line a

  (-3, 1) -(1, 4) = (-4, -3) . . . line b

  (0, 2) -(3, -2) = (-3, 4) . . . line c

When the (∆x, ∆y) values are identical, the lines are parallel. If the values are swapped, and one differs in sign, the lines are perpendicular.

  line b is perpendicular to lines a and b, which are parallel

__

2. When all of the equations are written in standard form, they are ...

4x +y = 7 . . . line ax -4y = 2 . . . line bx -4y = 3 . . . line c

As above, when the x- and y-coefficients are identical, the lines are parallel. If they are swapped and one is negated, the lines are perpendicular.

  line a is perpendicular to lines b and c, which are parallel
