Answer:
x.
Step-by-step explanation:
If h(x) is the inverse of f(x) them h(f(x)) = x.
question no.1
here, f (2) is given so
f (x)= x-4
f (2)=2-4
f (2)=-2
so ,the functional value f (x)= -2
Answer:
$120.00
Step-by-step explanation:
2000/100 = $20 = 1%
20x12 = $240 = annual intrest = 12m
June 15 - December 15 = 6m
240/2 = $120 for half a year intrest!
Answer:
7x2 + 14x = 0
x2 + 3x -5 = 0
x2 - x = 3x + 7
Step-by-step explanation:
A quadratic equation has the highest power of x to the second power. It must have x to the second power
7x2 + 14x = 0 quadratic
x3 - 3x2 + 1 = 0 not quadratic but cubic
5x - 7 = 0 not quadratic but linear
x2 + 3x -5 = 0 quadratic
x - 5 = 9x + 7 not quadratic but linear
x2 - x = 3x + 7 quadratic
Answer:
The answer to this question can be described as follows:
Step-by-step explanation:
Given equation:

As in the given question the two ways to solve the equation can be defined as follows:
First way:
Let square the above-given equation then we will get:

The calculated equation doesn't have any like term that's why it can't be factorised.
Second way:
after calculating the equation that is
