From the table, the domain are all real numbers and they can be substituted for x to return a valid f(x) value:

  • f(x) = x²
  • Domain = 2, 3, 4, 15 and x.
  • Range = 4, 9, 16, 225 and x².

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a Cartesian coordinate, which are the x-axis and y-axis.

By critically observing the table (see attachment), we can logically deduce that relationship between the amount of ink and the size of the sign is modeled by this function:

f(x) = x²

From the table, the domain are all real numbers and they can be substituted for x to return a valid f(x) value:

  • Domain = 2, 3, 4, 15 and x.
  • Range = 4, 9, 16, 225 and x².

Arthur has 6 more than 5 times the number of pencils as Jenny. If Arthur and Jenny combined have 30 pencils, how many pencils do
pashok25 [27]

Answer:

Jenny has 4 pencils.

Step-by-step explanation:

Let

Jenny has pencils = x

Arthur has pencils = 5x+6 (Arthur has 6 more than 5 times the number of pencils as Jenny. )

Total pencils = 30

We need to find how many pencils does Jenny have.

We basically can write the equation:

Total pencils = Jenny pencils + Arthur pencils

Putting values and solving to find value of x:

30=x+5x+6\\30=6x+6\\30-6=6x\\24=6x\\=> 6x=24\\x=\frac{24}{6}\\x=4

So, we have value of x = 4

Now, finding number of Jenny pencils:

Jenny has pencils = x = 4

Therefore, Jenny has 4 pencils.

What is the slope of the line that passes through the points (-8, -3) and
Alchen [17]

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 8, - 3) and (x₂, y₂ ) = (- 12, - 3)

m = \frac{-3+3}{-12+8} = \frac{0}{-4} = 0
