1) 2x + 9  = 2x -5

            9 ≠ -5 ; No solution

2) 2x-  1 = x + 3

   x = 4; One solution x = 4

3) x + 2 = x + 2

   0 = 0; Identity (or all real numbers)

Under her cell phone plan, Peyton pays a flat cost of $48 per month and $3 per gigabyte. She wants to keep her bill at $60.60 pe
Ad libitum [116K]

Answer: 4.20 gigabyte

Step-by-step explanation:

Based on the information given in the question, the equation that can be used to determine the the number of gigabytes of data Peyton can use while staying within her budget will be:

48 + 3g = 60.60

3g = 60.60 - 48

3g = 12.60

g = 12.60/3

= 4.20

The number of gigabytes of data is 4.20g

Use quadratic formula to find both solutions to the quadratic equation given below . 3x^2-5x-1=0
Rudiy27

Answer:

x1=\frac{5+\sqrt{37}} {6}

x2=\frac{5-\sqrt{37}} {6}

Step-by-step explanation:

we know that

The formula to solve a quadratic equation of the form ax^{2} +bx+c=0 is equal to

x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}

in this problem we have

3x^{2} -5x-1=0  

so

a=3\\b=-5\\c=-1

substitute in the formula

x=\frac{5(+/-)\sqrt{(-5)^{2}-4(3)(-1)}} {2(3)}

x=\frac{5(+/-)\sqrt{37}} {6}

x1=\frac{5+\sqrt{37}} {6}

x2=\frac{5-\sqrt{37}} {6}
