Answer:

c=-37/42 b=-71/42 a=9/14

Step-by-step explanation:

Find what c is equal to using terms of a and b

c=16-4a-3b

Do the same for a using terms of c and b

a=11+3b-2c

Plug in a terms into c equation

c=16-4(11+3b-2c)-3b=-28/3-5b

Plug in c term into a equation

a=11+3b-2(16-4a-3b)=21/9-b

Plug in both a and c equations into 11a-2b+3c=45

11(21/9-b)-2b+3(-28/3-5b)=45

distribute and simplify to get that b=-71/42

plug in b to your c equation

c=-28/3-5x-71/42=-7/42

plug in b to a equation

a=21/9-(-71/42)=9/14

Find the values of a and b such that x2 - 2x + 2 = (x -a) + b LOADS OF POINTS ON THE LINE!!!
Hitman42 [59]

Answer:

Step-by-step explanation:

Factorize using square root method.

x² - 2x + 2 = (x-a)² + b

x² -2x + 1 + 1 = (x-a)²+b

(x² - 2*x*1 + 1²) + 1 = (x -a)²+ b       {Compare with a²- 2ab+b² which is (a - b)²}

(x - 1)² + 1 = (x - a)² + b

a = 1 and b = 1

2. / 250

3. / 375

4. / 500

5. / 625

2.

f(x)= 125 x views=125.hours

The slope of the function equals the visits of each hour.

3. (1;125) (2;250) (3;375) (4;500) (5;625)

4. "views as a function of hours"

5. in 12 hours the website will have f(12)=125 . 12 = 1500 views.

we can see in the plot that the line gets to that number for 8

Which of the following pairs of functions are inverses of each other ​
Ghella [55]

Option (A) represents the function and its inverse of a function option (A) is correct.

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function and inverse of a function shown in the picture.

Checking for option (A):

\rm f(x) = \dfrac{x}{4}+10 \ \ \ and \  \ \ g(x)  = 4x -10

Taking f(x):

\rm f(x) = \dfrac{x}{4}+10

To find the inverse of a function interchange the x and y variables:

f(x) → x

x  → g(x)

\rm x = \dfrac{g(x)}{4}+10

Solving:

4x = g(x) + 10

g(x) = 4x - 10

Similarly, we can find the inverse of a function.

Thus, option (A) represents the function and its inverse of a function option (A) is correct.
