oc/) = 1 - 1
OD. (I) = 12 - 211

Answers

Answer:

Gah! Inverses!

Step-by-step explanation:

This is a pretty simple concept, just switch the x and f(x) values!

If you don't understand, look at how I solve it!

[tex]f(x)=\frac{1}{3} -\frac{1}{21} x[/tex]

Switching the positions of the x and f(x) values...

[tex]x=\frac{1}{3} -\frac{1}{21} f(x)^{-1}\\[/tex]

Note: That f(x)^-1 is the proper notation for inverse functions.

[tex]x-\frac{1}{3} =-\frac{1}{21} f(x)^{-1} \\f(x)^{-1}=-21x+7[/tex]

There you go!

Hope this helps, and don't procrastinate!

A store buys a camera for $80 and decides to markup the price 35%. How much does the camera sell for?

Answers

Step-by-step explanation:

80$ is original price so 100%

markup by 35% make price 135%

crossmultiplication

ans=108

Based on the cost of the camera and the percentage markup, the selling price of the camera is $108.

The camera's selling price is 35% more than its cost price. That 35% is:

= 80 x 35%

= $28

The selling price of the camera is therefore:

= Cost of camera + Increase

= 80 + 28

= $108

In conclusion, the camera is being sold for $108.

Peter​ says, "If you subtract 12 from my number and multiply the difference by −7​, the result is −175​." What is Peter​'s ​number​

Answers

Answer:

37

Step-by-step explanation:

let’s say peter’s number is x

(x-12)(-7) = -175

-7x + 84 = -175

-7x = -259

x = 259/7

x = 37

Answer:

The number is 37.

Step-by-step explanation:

-175 ÷ -7 = 25

25 + 12 = 37

You have to work backwards from -175 by doing the reverse of what peter did to get the original number.

From what I can see two points of the line are (0,1) and (5,4) so you can just count and do rise/run which is y/x or the formula which is like y^2-y^1/x^2-x^1 they both get the same answer which is 3/5

The directions on a sewing pattern say to buy an extra 12.5% of fabric to account for error. Sam needs 2.75 yards of fabric to make a shirt, so he buys 2.4 yards. Choose the correct statement.

A.Sam bought the correct amount of fabric because he bought what was suggested.

B.Sam bought the correct amount of fabric because he needs less than 2.4 yards.

C.Sam did not buy the correct amount of fabric because he needs less than 2.4 yards.

D.Sam did not buy the correct amount of fabric because he should have bought 3.09 yards​

Answers

Answer:

Sam should have bought 3.09 yards of fabric instead of 2.4 yards

So, Option D is correct.

Step-by-step explanation:

Total fabric needed by Sam = 2.75

According to directions on a sewing pattern they say to buy an extra 12.5%

So, extra fabric would be: 12.5% of 2.75

Solving

[tex]12.5\% \ of \ 2.75\\=\frac{12.5}{100}\times 2.75 \\=0.343[/tex]

Now adding 0.343 into 2.75 to get extra fabric quantity:

2.75+0.343

=3.09

Therefore Sam should have bought 3.09 yards of fabric instead of 2.4 yards

So, Option D is correct.

A total of 202 tickets were sold for a theatre showing. If child tickets cost $6 and adult tickets cost $10, how many tickets of each were sold if the theatre earned a total of $1708.

Answers

Answer:

167 adult tickets were sold

35 children tickets were sold

Step-by-step explanation:

Let the number of adult tickets be x

Let the number of children tickets be y

Total number of each ticket sold;

x + y = 202 equation 1

Total cost of the tickets

10x + 6y = 1708 equation 2

Let

x= 202 - y equation 3

Substitute 3 into 2

10(202 - y) + y = 1708

2020 - 10y + y = 1708

-9y = 1708 - 2020

-9y = -312

y= 35

Substitute y =35 into 1

x + 35 =202

x= 202 - 35

x= 167

Therefore;

167 adult tickets were sold

35 children tickets were sold

im sorry if it was wrong it was what I got

Step-by-step explanation:

Write an equation in​ point-slope form of the line that passes through the given​ points, then write the equation in​ slope-intercept form. ​(​-6,6), (6,2)

Answers

Point-Slope form = y-y1=m(x-x1)

Y-6 = -1/3 (x+6)

Slope-intercept form = Y=mx+b

y = -1/3 + 4

The equation of line is y= -2/3x + 2.

What is Slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

Points: (​-6,6), (6,2)

Slope= (-2 - 6)/( 6 -(-6))

slope= -8 / 12

slope= -2/3

Now, using slope intercept form

y-b = m(x- a)

y- 6 = -2/3( x + 6)

y -6 = -2/3x - 4

y= -2/3x + 2

Hence, the equation of line is y= -2/3x + 2.

Step-by-step explanation:

2x - 3y = -4  multiply both sides by 3 by adding paranthesis to represent this

3( 2x - 3y ) = 3 (-4)   Then use distributive property for the left side equation

6x - 9y = -12               Finally just multiply -4 by 3 and you get this equation

D. Neither graph 1 nor graph 2 represent a proportional relationship.

B. Graph 2 represents a proportional relationship, but graph 1 does not.

Step-by-step explanation:

All proportional relationships pass through the origin. Graph 2 does but Graph 1 does not. Additionaly, Graph 2 is a straight line that represents a proportional relationship. Another way to find out if it is proportional is to find the constant of proportionality by dividing the y by the x in different parts of the line. The numbers should all have the same constant of proportionality.

15/3 = 5

10/2 = 5
