steps)7-2n=3

then you move the constant to tge right hand side and change its sign

-2n=3-7

then

calculate the difference

-2n=3-7

-2n= -4

Divide both sides

The graph of function f is shown on the coordinate plane. Graph the line representing function g, if g is defined as shown below

Aleonysh [2.5K]

Answer:

$g(x)=x-1$

Step-by-step explanation:

Any problem of this kind should first be approached by solving the initial function.

This question is based on curve translation on x-axis. But, there can be questions asked on translation in both axes, rotation of curve about origin, or both combined.

Initial function f(x) is a straight line from picture.

Common equation of straight line is

$y=mx+c$

m= slope of the line

c= y-intercept

Slope of the line:

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

Let those points on graph be A(3,0) and B(0,-6)

Therefore, slope of line AB, using formula is:

$m=\frac{0-(-6)}{3-0}$

m=2

And c=(-6)

And equation of line AB is:

$y=2x-6$

$f(x)=2x-6$

Now this line is translated backwards by 2 units, (x) becomes (x+2)

Let us consider a X, such that, $X=x+2$

$f(X)=2X-6$

$f(x+2)=2(x+2)-6$

$f(x+2)=2x+4-6$

$f(x+2)=2x-2$

Now, there is another function such that, $g(x)= \frac{1}{2} f(x+2)$

$g(x)= \frac{1}{2}(2x-2)$

$g(x)= x-1$ ; according to your question.

In the picture, they are asking for a function, $g(x)= \frac{-1}{2} f(x+2)$

Then, $g(x)= -x+1$ ; according to the picture.

Here, I have attached a file showing all the graphs for clear understanding.

A drama club earns $1400 from a production it sells a total of 64 tickets adult tickets and 132 student tickets in adult ticket

Ket [755]

Answer: an adult ticket cost $8 and a student ticket cost $4

Step-by-step explanation:

Let x represent the cost of one student ticket.

Let y represent the cost of one adult ticket.

A drama club earns $1040 from a production. It sells a total of 64 adult tickets and 132 student tickets. It means that

132x + 64y = 1040 - - - - - - - - - -1

An adult ticket costs twice as much as a student ticket. It means that

y = 2x

Substituting y = 2x into equation 1, it becomes

132x + 64 × 2x = 1040

132x + 128x = 1040

260x = 1040

x = 1040/260 = 4

y = 2x = 2 × 4

y = 8

Isa finished 30% of his homework in 27 minutes. How many more minutes will it take Isa to complete his homework, assuming that h

Brilliant_brown [7]

Answer:

90 Minutes

Step-by-step explanation:

If he took 27 minutes to do 30% of his homework, then we can reverse the operation to find the total amount

30% is the same as 0.3, therefore you divide 27 by 0.3 because the 100% is 1, so by dividing you'll get the 100%.
