Which graph represents a nonlinear function?​

9514 1404 393

Answer:

  B.  9

Step-by-step explanation:

This is probably most easily evaluated by finding f(4) and then g(f(4)).

  [tex](g\circ f)(4)=g(f(4))=g(-4^3)=g(-64)\\\\=\left|\\\dfrac{1}{8}\cdot(-64)-1\right|=\left|-\dfrac{64}{8}-1\right|=|-9|\\\\\boxed{(g\circ f)(4)=9}\qquad\textbf{matches B}[/tex]

Answer:

-2

Step-by-step explanation:

8(-a)^2+24*-a=80

or,8a^2-24a=80

or,8a^2-24a-80=0

or,8(a^2-3a-10)=0

or,a^2-3a-10=0

or,a^2-(5-2)a-10=0

or,a^2-5a+2a-10=0

or,a(a-5)+2(a-5)=0

or,(a-5)(a+2)=0

either,

a-5=0

•°•a=5

or,

a+2=0

•°•a=-2(negative integer)

The value of the unknown integer is -2.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given data eight times the square of a negative integer plus 24 times the negative integer equals 80 in the form of the mathematical expression will be written as:-

8(-a)²+24-a=80

8a²-24a=80

8a²-24a-80=0

8(a²-3a-10)=0

a²-3a-10=0

a²-(5-2)a-10=0

a²-5a+2a-10=0

a(a-5)+2(a-5)=0

(a-5)(a+2)=0

a-5=0

a=5 or, a+2=0 a=-2

Therefore, the value of the unknown integer is -2.

Answer:

x=2

Step-by-step explanation:

4 (x + 6) - 3x = 26

solve the parenthesis

4x + 24 - 3x = 26

subtract 24 from both sides to get x by itself

4x - 3x = 2

solve

x = 2

The order of  functions from narrowest graph to widest graph is 3x²,    -x,  x² and 2x. A graph is a structure that amounts to a set of items.

A graph is a structure that amounts to a set of items in which some combinations of the objects are already in some manner "connected" in discrete mathematics, more specifically within graph theory.

The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge. A graph is typically shown diagrammatically as a collection of dots as well as circles representing the vertices and lines or curves representing the edges. The order of  functions from narrowest graph to widest graph is 3x²,    -x,  x² and 2x.

Therefore, the order of  functions from narrowest graph to widest graph is 3x²,    -x,  x² and 2x.

Step-by-step explanation:

Answer:

Monica = 48.50

Samuel = 24.25

Kara = 17.25

Step-by-step explanation:

First you write equations as you are reading the text:

m = 2s ("Monica earned twice as much as Samuel")

s = k+7 ("Samual earned 7 more than Kara")

m = 48.50

Next, you convert these equations to solve for s and k respectively.

So, if m=2s, then s=m/2:

s = m/2 = 24.25

Likewise, if s=k+7, then k=s-7

k = s-7 = 17.25

The difference between greatest and least is 48.50 - 17.25 = 31.25

Answer:

[tex]\frac{4}{3}[/tex]

Step-by-step explanation:

The average rate of change can be found by using the following formula

[tex]\frac{f(x_{2}) - f(x_{1}) }{x_{2} - x_{1}}[/tex]

Since the interval goes from -7 to 2, we should find the y-values that correspond to x=-7 and x=2.

By inspection of the graph, we can clearly see that when x is -7, y is -7 as well and when x is 2, y is 5.

Now that we know this, we can simply plug these values into the formula!

[tex]\frac{f(2) - f(-7) }{2 - (-7)} = \frac{5 - (-7)}{2 - (-7)} = \frac{5 +7}{2+7} = \frac{12}{9} = \frac{4}{3}[/tex]

Good luck!

Answer:

18$

Step-by-step explanation:

Answer: (13 + y) / 5

Step-by-step explanation:

Since Grandma Gertrude gave 13 pieces of jewelry and Grandma Fien gave y pieces of jewelry to the Carlson sisters, the total jewellery given to the sisters will be:

= 13 + y

Since there are 5 Carlson sisters, the number of pieces of jewelry that each sister receive will be:

= Total jewelries / Number of sisters

= (13 + y) / 5

Answer:Grandma Gertrude gave 131313 pieces of jewelry and Grandma Fien gave yyy pieces, so the sisters received a total of 13+y13+y13, plus, y pieces of jewelry.

The sisters divided the 13+y13+y13, plus, y pieces of jewelry evenly among themselves, and there were 555 sisters. So each sister received \dfrac{13+y}{5}

5

13+y

​

start fraction, 13, plus, y, divided by, 5, end fraction pieces of jewelry.

Each sister received \dfrac{13+y}{5}

5

13+y

​

start fraction, 13, plus, y, divided by, 5, end fraction pieces of jewelry.

Graph: Closed circle at 11, shading to the right

======================================================

Work Shown:

[tex]x+7 \ge 18\\\\x+7-7 \ge 18-7\\\\x \ge 11[/tex]

In the second step, I subtracted 7 from both sides to undo the "plus 7".

To graph this, we place a closed or filled in circle at 11. Then we shade to the right. The endpoint x = 11 is included as part of the solution set, which is why we use a closed circle instead of an open hole.

This visually describes all values that are equal to 11 or larger than 11.
