Answer:
f-1(x)=-
x-
Step-by-step explanation:
First, switch f(x) to the variable "y".
y=-
x-8
Next, swap "x" and "y" with each other.
x=-y-8
Next, lets move the denominator of 2 to the other side by multiplying both sides by 2. Your result will be...
2x=-3y-16
Now move -16 to the left side.
16+2x=-3y
To get "y" by itself, lets divide each side by -3. Our result is...
y=-x-
To finish the problem off, replace y with f-1(x) and your complete answer will be...
f-1(x)=-x-

Step-by-step explanation:
Answer: Y = 7x/2 -2
Step-by-step explanation:
Y intercept of -2 means there's a point at (0,-2).
Given the two points (4,12) and (0,-2), we can now find the slope
12-(-2)/4-0 = 14/4 = 7/2 which is the slope
so the equation is Y = 7x/2 -2
The factors are 17 and 3.
The given conditions are two factors of the first number, 51 such that their product is 51 and the sum is the second number 20.
let say, the factors are x and y.
therefore, we can write, x.y = 51 ... (1) and x + y = 20 .... (2)
Putting the value of x from equation (2) in equation (1) we get,
(20 - y).y = 51
or, 20y - y² = 51
or, y² - 20y + 51 = 0
or, y = 17, 3
then x = 3,17
Therefore, The factors are 17 and 3.

To find the area of the paper. You must multiply the width and the height, which is 9 and 19.
9 x 19 is 171
And multiply that by 4
171 x 4 = 684
Total area is 684
