7.05 as a fraction and as a percent

yes since you multiply the x number by 3 to get y

Graph that represents the function f(x) and  [tex]f^{-1}(x)[/tex] is the first graph

Option A

Given :

The graph of some functions are given

we need to find out which graph represents the function f(x) and f inverse (x)

we know that [tex]f^{-1}(x)[/tex] is obtained by reflection the graph of f(x) about the line y=x

We look at the graph where f(x) is reflected about the line y=x

In the first graph we can see that the graph has a reflection about the line y=x

Option A graph represents the function f(x) and  [tex]f^{-1}(x)[/tex]

Answer:

(23/2, 1/2)

Step-by-step explanation:

Let's solve this system through elimination by addition/subtraction:

Divide all three terms of the first equation by 3.  This results in the equivalent system

-2x - 2y = 33

2x + 4y = -32

Combining like terms results in:

2y = 1, and so y = 1/2.

Let's use the first equation and y = 1/2 to find x:

-6x - 6(1/2) = 66

This becomes -6x - 3 = 66, or -6x = 69, or x = -69/6 , or x = 23/2

The solution is thus (23/2, 1/2)

Answer:

110

Step-by-step explanation:

y = 11/6x where x is in minutes

there are 60 minutes in an hour

plug in 60 as x

11/6 *60 = 11*10 = 110

Answer:

(0, 50) (25, 57.5) (50, 122.5) (75, 195) (100, 275)

Step-by-step explanation:

We know that he earns 30% percent of the money made on sales, plus $50 a week. We know that he starts off with 50, because that's how much he made by working that week. To figure out how much money he made off of each one, we have to calculate 30% of the sale, and add that to the total amount of money he has made up to that point. I hope this helps :)

Answer:

y=50x(.3)+30

Step-by-step explanation:

You get an average of $50 per week and then work 30 hours per week but the outcome is multiplied by .30 from the sales commision so the answer would be y=50x(.3)+30

Answer:

EG is perpendicular to HF

Step-by-step explanation:

We know this because in order for two segments to be perpendicular there has to be a right angle. And there is a right angle therefore segment EG is perpendicular to segment HF

Answer:F is perpindicular to G

Step-by-step explanation: Well I think this because they both have angles but im kinda confused to this is just a guess

Answer:

(2,5)

Step-by-step explanation:

Coordinates means where the numbers line up to the point.

So first you go to the x-axis and look for te number that leads to the point and you do that with the y-axis too and you get (2,5) as the coordinates.

Answer:

Step-by-step explanation:

Volume of triangular prism=120in³

Area of triangle ×length =120in³

1/2×6×x×4=120in³

12x=120

X=120/12=10in

Answer:

Step-by-step explanation:

f(x)= 36( 1 - 0.12)^x. F(x)= 36(0.88)^3. f(x)= 95.04    190-95.05 = 94.95 degree.

Because the temperature is going down, we will use (1-0.12) instead of (1+0.12). X=3 because it is what temperature after 3 min. x= time.

I don't understand the question that well, but please don't report me. I will fix it if I can.

Answer:

A. 5

Step-by-step explanation:

You have $15.

1 box = $3

3x _= 15

3x 5=15

So, 5 boxes of candy, you can buy for $15.

Answer:

A: 5

Step-by-step explanation:

ech box cost 3 dollars and we have 15 dollars  

3 x 5 = 15 so we can get ( A:5 ) boxes of candy

Step-by-step explanation:

Answer:

60degrees

Step-by-step explanation

To get the angle x, you must first know that the sum of angle at a point is 360degrees. Hence;

x + <ADB + <CDB  = 360

x +150 + 150 = 360

x+ 300 = 360

x = 360 - 300

x = 60

Hence the value of x is 60degrees

Answer:

c = 1.05p

Step-by-step explanation:

the price of the hat before the increase was 100%, after the increase it becomes 100 + 5% = 105%. Representing it as a decimal becomes 1.05p

Let illustrate with an example.

The price of a hat was $100, after the 5% increase. the cost of the hat becomes

100 + (0.05 x 100) = 105

To find the percentage increase

divide 105 by 100 and subtract 1

(105/100) - 1 = 1.05

Answer:

18 cm and 42 cm

Step-by-step explanation:

a = wl

7w = 3l, then l = 7/3w

756 = w(7/3w)

756 = 7/3w²

w² = 324

w = 18

l = 42

Step-by-step explanation:

Answer:

m<S = [tex]35.3^{o}[/tex]

Step-by-step explanation:

Applying the sine rule to the given question, we have;

[tex]\frac{r}{Sin R}[/tex] = [tex]\frac{s}{Sin S}[/tex]

[tex]\frac{24}{Sin 120}[/tex] = [tex]\frac{16}{Sin S}[/tex]

cross multiply to have,

16 x Sin 120 = 24  x Sin S

16 x 0.8660 = 24 Sin S

13.856 = 24 Sin S

Sin S = [tex]\frac{13.856}{24}[/tex]

         = 0.57733

S = [tex]Sin^{-1}[/tex] 0.57733

  = 35.2630

Thus, m<S = [tex]35.3^{o}[/tex]
