Answer:

Step-by-step explanation:

If one standard frequency scale is 220 hertz

Then the number of scales 1100 hertz frequency can be calculated as follows

= 1100/220

= 5

Hence 5 scales are present in 1100 hertz frequency

The function g is defined as follows for the domain given. g(x) = 2 - 2x , domain = \{- 1, 0, 1, 2\} Write the range of g using

Musya8 [376]

Explanation:

The function is given below as

$g(x)=2-2x$

The set of domains is given below as

$\lbrace-1,0,1,2\rbrace$

Step 1:

Put x=-1

$\begin{gathered} g(x)=2-2x \\ g(-1)=2-2(-1) \\ g(-1)=2+2 \\ g(-1)=4 \end{gathered}$

Step 2:

Put x=0

$\begin{gathered} g(x)=2-2x \\ g(0)=2-2(0) \\ g(0)=2 \end{gathered}$

Step 3:

Put x=1

$\begin{gathered} g(x)=2-2x \\ g(1)=2-2(1) \\ g(1)=2-2 \\ g(1)=0 \end{gathered}$

Step 4:

Put x=2

$\begin{gathered} g(x)=2-2x \\ g(2)=2-2(2) \\ g(2)=2-4 \\ g(2)=-2 \end{gathered}$

Hence,

The range of g(x) using set notation will be

$\Rightarrow\lbrace4,2,0,-2\rbrace$

Hence,

The graph of g(x) is given below as

PLEASE HELP ANSWER THIS QUESTION I DON'T KNOW IT AT ALL

Answer:

Is y = 4x - 7 a linear function?
Is y = 6x² - 1 a linear function?
Is y = $\frac{1}{2x}$ + 10 a linear function?

Step-by-step explanation:

Yes it is - when you graph this equation, it results in a [straight] line, signalling that it is a linear function.
No it's not - when you graph this equation, it results in a v- kinda shape on the graph. Linear functions are [straight] lines on a graph, and this line wasn't straight. In fact, this wasn't even a line.
No it's not - when you graph this equation, it results in a bend at the origin. The line on the graph is not straight, so this is not a linear equation.

For the graphs -

The first one represents the linear function [y = 4x - 7]

The second one (that looks like an L) represents the last not linear function [y = $\frac{1}{2x}$ + 10]

The third one (that looks like a V) represents the first not linear function [y = 6x² - 1]

A family has two cars. The first car has a fuel efficiency of 40 miles per gallon of gas and the second has a fuel efficiency of

kozerog [31]

Answer:

Step-by-step explanation:

Let x = gallons consumed by car 1

Let y = gallons consumed by car 2

We set up our equations:

35x+40y = 1850 eq1

x+y = 50 eq2

Substituting eq 2 into eq 1,

35x+40(50-x) = 1850

35x+2000-40x = 1850

-5x+2000 = 1850

-5x = -150

x = 30

Substitute value of x into eq 2.

x+y = 50

30+y = 50

y = 20

Car 1 consumes 30 gallons of gas.

Car 2 consumes 20 gallons of gas.

Komok [63]

Checking the numbers that are greater than 10 in this set, we have:

11.2 and 12

The numbers in this set that are lesser than or equal 9 are:

0, 4.5, 5 and 9

Solving the inequality, we have:

$\begin{gathered} x+3>10 \\ x>10-3 \\ x>7 \end{gathered}$

Three values greater than 7 are:

8, 9, 10

Solving the inequality, we have:

$\begin{gathered} 3x$

Three values smaller than 5 are:

4, 3, 2

Solving the inequality, we have:

$\begin{gathered} \frac{x}{5}\ge2 \\ x\ge2\cdot5 \\ x\ge10 \end{gathered}$

Three values greater than or equal 10 are:

10, 11, 12
