Answer:
(x) = √ x + 4
Step-by-step explanation:
step 1) replace f(x) with y
y = x² - 4
step 2) switch the x and y (because every (x, y) has a (y, x))
x = y² - 4
step 3) add 4 to both sides of the equal sign
x + 4 = y²
step 4) take the square root of both sides of the equal sign (the square root symbol cancels out the ²)
√ x + 4 = y
step 5) you know have the inverse of f(x) = x² - 4
(x) = √ x + 4
Answer:
<em>The distance between the points (1, 7) and (10, 1) is 10.82 units</em>
Step-by-step explanation:
<u>Distance between two points
</u>
The distance between points A(x,y) B(w,z) can be calculated with the formula:

We are given the points (1,7) and (10,1), let's use their values and compute the required distance:



The distance between the points (1, 7) and (10, 1) is 10.82 units
Answer:
C
Step-by-step explanation:
Hi there!
The Eqn. is :-
1.5 (x + 4) - 3 = 4.5 (x - 2)
1.5x + 6 - 3 = 4.5x - 9
Combining the like terms :-
1.5x - 4.5x = - 9 - 6 + 3
- 3x = - 15 + 3
- 3x = - 12
x =

x = 4
Hence, the required answer is → x = 4
