if f(9) = -14, then what will be the value of f^-1(-14)

Answers

Answer:

Step-by-step explanation:

Since f and f⁻¹ are inverse functions, the domain of the one equals to the range of the other:

f(9) = -14 ⇒ f⁻¹(-14) = 9

helpp me i dont know the answer

Answers

Answer: k = -1

2m = -6 that means m = -3
You can tell by dividing -6 by 2 to get -3

Now we know m = -3 let’s put that in the equation

3(-3) - 4k = -5

-9 - 4k = -5

Just try the option you have to figure it out. You know it’s not -3.5 or 3.5 because it’s a whole number so it wouldn’t be anything that’s a decimal.

-9 - 4(1) = ?

-9 - 4 = 13

Now let’s try doing -1

-9 - 4(-1) = ?

-9 - -4 = -5

Write the equation of a line that is perpendicular to y = 1/2x - 7 with a y-intercept of 15.
What is the perpendicular slope?
What is the new equation?

Answers

Answer:

m = -2

y = -2x + 15

Step-by-step explanation:

so it's asking for the perpendicular slope so perpendicular means negative reciprocal so the negative reciprocal of 1/2 is -2

and since the question has already provided the y intercept, just write out the new equation in slope intercept form so y = -2x + 15. hope this helps

Answer:

11.0

Step-by-step explanation:

10.962 rounded to the nearest tenth:

10.962 ≈ 11.0 ⇒ round up 9 to 10 since the previous number is greater than 5, it adds 1 to 10 and makes it 11, and 9 is replaced with zero

4.what equation passes through the 2 points
(2, 1) and (6, 9)

Answers

Answer:

y = 2x - 3

Step-by-step explanation:

Finding the slope:

[tex]\frac{y2-y1}{x2-x1}[/tex]

= (9-1)/(6-2)

= 8/4

= 2

Slope: 2

Substituting this value into the equation 'y=mx+c':

y = 2x + c

Substituting any points (in this case, (2,1)) into the above equation:

1 = 2(2) + c

1 = 4 + c

c = 1 - 4

c = -3

Hence,

y = 2x - 3

Hope this helps and be sure to have a wonderful time ahead at Brainly! :D

Answer:

y=2x-3

Step-by-step explanation:

first put in the equation:

[tex]\frac{9-1}{6-2}[/tex] and you get 8/4 which equals 2. so this is your slop.

now put in this equation:

[tex]y-y_{1}=m(x-x_{1})[/tex]

so you put in (2-1)

[tex]y-1=2(x-2)[/tex]

and you get

y-1=2x-4

and if u add 1 to both sides you get y=2x-3

Answer:

The train appears to go the same distance each minute

9mins

The cost for each person appears to be the same

Step-by-step explanation:

So for the first qu you basically want to find the distance the train travels each minute, so for

3mins : 9km

therefore

1min : 3km

basically divide 9 by 3

then the train travels 27km, how long does it take?

if 3km = 1min

then 27/3 = 9

so it takes the train 9 minutes

Then for the second qu you'll do the same thing

2ppl : $16

so one person : 16/2

so 1 person costs $8

so for 8 ppl you multiply 8 by 10

8ppl : $80

hope this helps:))))

lin drew a triangle and a dilation of a triangle with scale factor 1/2. what is the center of the dilation?

A grocery store sells a case of 24-500ml bottles of water for $2.99. They also Sell a case of 6-1.5 L bottles for $2.99. Which bottles are the best by? How much are you saving per liter?

Answers

Answer:

24 - 500ml bottles; $.08 per L

Step-by-step explanation:

1 liter = 1,000 ml

so 500ml = .5 L

Now compare the amount of water: 24 at .5L = 12L

6 at 1.5L = 9L

So the 12L /24 = .5 L per bottle cost about $.25

1.5L/ 6 = .25 L per bottle cost about $.33
