N^2-5n-24 show all work

romanna [79]

Answer:

-3,8

Step-by-step explanation:

1) we can factor this since this quadratic function is in the form of

ax^2+bx+c

where we need to find out what*what=c

and what+what=b

since c is -24 and b is -5 we need to figure out the factors of -24 which equal -5:

-8+3=-5

and

-8*3=-24

hence -8 and 3 is our factors, next we will substitute them in place of "b"

n^2-8n+3n-24

split this equation in two groups:

group 1) n^2-8n

group 2) 3n-24

gcf of group 1= n

n(n-8)

gcf of group 2: 3

3(n-8)

next take numbers outside of parentheses and group them together:

so (n+3) (n-8)=0

since anything times 0 is equal to 0, either (n+3) is 0 or (n-8) is 0

n+3=0

n=-3

n-8=0

n=8

hence n=-3,8

Hope this helps!

A trail mix recipe requires 5 cups of mixed nuts, 1 cup of raisins, 2 cups of chocolate chips, and 3 cup of pretzels for one bat

Tcecarenko [31]

Answer:

Step-by-step explanation:

Mixed Nuts = 5 cups

Raisins = 1 cup

Chocolate chips = 2 cups

pretzels = 3 cups

Ingredients for 2 batches

Multiply all ingredients by 2

Mixed Nuts = 5 cups × 2

Raisins = 1 cup × 2

Chocolate chips = 2 cups × 2

pretzels = 3 cup × 2

Mixed Nuts = 10 cups

Raisins = 2 cups

Chocolate chips = 4 cups

pretzels = 6 cups

Ingredients for 3 batches

Multiply all ingredients by 3

Mixed Nuts = 15 cups

Raisins = 3 cups

Chocolate chips = 6 cups

pretzels = 9 cups

Ingredients for 4 batches

Multiply all ingredients by 4

Mixed Nuts = 20 cups

Raisins = 4 cups

Chocolate chips = 8 cups

pretzels = 12 cups

Ingredients for 5 batches

Multiply all ingredients by 5

Mixed Nuts = 25 cups

Raisins = 5 cup s

Chocolate chips = 10 cups

pretzels = 15 cups

Which table represents a function? A 2-column table with 4 rows. The first column is labeled x with entries negative 3, 0, negat

tangare [24]

Answer:

This is a many-to-one function as the value of y = -1 corresponds to two values of x:

$\begin{array}{|c|c|}\cline{1-2} x & y\\\cline{1-2} -3 & -1\\\cline{1-2} 0 & 0\\\cline{1-2} -2 & -1\\\cline{1-2} 8 & 1\\\cline{1-2}\end{array}$

Step-by-step explanation:

Function

A special relationship where each input (x-value) has a single output (y-value).

A function is one-to-one if each value in the range (y-values) corresponds to exactly one value in the domain (x-values).

A function is many-to-one if some values in the range (y-values) correspond to more than one (many) value in the domain (x-values).

This is a many-to-one function as the value of y = -1 corresponds to two values of x:

$\begin{array}{|c|c|}\cline{1-2} x & y\\\cline{1-2} -3 & -1\\\cline{1-2} 0 & 0\\\cline{1-2} -2 & -1\\\cline{1-2} 8 & 1\\\cline{1-2}\end{array}$

This is not a function as the value of x = -5 corresponds to two values of y:

$\begin{array}{|c|c|}\cline{1-2} x & y\\\cline{1-2} -5 & -5\\\cline{1-2} 0 & 0\\\cline{1-2} -5 & 5\\\cline{1-2} 6 & -6\\\cline{1-2}\end{array}$

This is not a function as the value of x = -2 corresponds to two values of y:

$\begin{array}{|c|c|}\cline{1-2} x & y\\\cline{1-2} -4 & 8\\\cline{1-2} -2 & 2\\\cline{1-2} -2 & 4\\\cline{1-2} 0 & 2\\\cline{1-2}\end{array}$

This is not a function as the value of x = -4 corresponds to two values of y:

$\begin{array}{|c|c|}\cline{1-2} x & y\\\cline{1-2} -4 & 2\\\cline{1-2} 3 & 5\\\cline{1-2} 1 & 3\\\cline{1-2} -4 & 0\\\cline{1-2}\end{array}$
