f(5) is -8 ⇒ 1st answer

Step-by-step explanation:

Function is a relation between set of of ordered pairs (x , y),and every x has only one y

Examples:

  • {(-1 , 2) , (2 , 4) , (5 , -3)} is a function because x = -1 has only y = 2, x = 2 has only y = 4 and x = 5 has only y = -3
  • {(-2 , 4) , (0 , -1) , (-2 , 5)} is not a function because x = -2 has y = 4 and 5

The notation of the function is f(x) = y

The table:

→    x     :    f(x)

→    -4    :    -2

→    -1     :    5

→     3    :    4

→     5    :   -8

From the table

∵ x = -4

- The corresponding value of y to x = -4 is -2

∴ f(-4) = -2

∵ x = -1

- The corresponding value of y to x = -1 is 5

∴ f(-1) = 5

∵ x = 3

- The corresponding value of y to x = 3 is 4

∴ f(3) = 4

∵ x = 5

- The corresponding value of y to x = 5 is -8

∴ f(5) =-8

f(5) is -8

Find the discriminant and the numbers of real roots for this equation: 4x^2+12x+9=0
Len [333]

Answer:

D=0

The quadratic equation has one real root with a multiplicity of 2.

Step-by-step explanation:

Given a quadratic equation:

 ax^2+bx+c=0

You can find the Discriminant with this formula:

D=b^2-4ac

<em> </em>In this case you have the following quadratic equation:

4x^2+12x+9=0

Where:

a=4\\b=12\\c=9

Therefore, when you substitute these values into the formula, you get that the discriminant is this:

D=(12)^2-4(4)(9)\\\\D=0

Since D=0, the quadratic equation has one real root with a multiplicity of 2 .

Which of the following is an example of a proper fraction?
nirvana33 [79]
The numbers should be less than the denominator, therefore i think it's 5/9 , because the rest have a numerator greater than the denominator, even the 3 . it's written as 3/1 and 3 >1.

Answer:

1. Each crayon weights 2 grams.

2. John can make 20 birthday cards in 1 hour.

Step-by-step explanation:

1. First we need to convert Kilograms into grams, to do this, we must multiply the # of Kgs by 1000. Then we need to solve for the mass of the crayon.

500c=1\\\\500c=1000\\\\c=\frac{1000}{500} \\\\c=2

Each crayon weights 2 grams.

2. First we need to convert 1 hour into minutes. As there are 60 minutes in an hour, we must multiply the number of hours by 60 to find the minutes. Then we can solve for the number of birthday cards.

3c=1\\\\3c=60\\\\c=\frac{60}{3} \\\\c=20

John can make 20 birthday cards in 1 hour.
