How to work out 5x+9=4

1 answer:

4 0

=> 5x + 9 = 4

Adding - 9 on both sides,

=> 5x + 9 - 9 = 4 - 9

=> 5x = - 5

Divide by 5 on both sides,

$= > \frac{5x}{5} = \frac{ - 5}{5}$

=> x = - 1

Hence the value of the variable x is - 1

Consider the function f (x) = x2.

klio [65]

Answer: The graph is shifted 2 units to the right.

Step-by-step explanation:

Given a function f(x), we know that one transformation rule is:

If $f(x-k)$ then the function is shifted "k" units to the right.

Therefore, for the function $f(x)=x^{2}$ , when we subtract 2 from the input, then we get the function g(x) in the form:

$g(x)=(x-2)^{2}$

We can conclude that subtracting 2 from the input of the function $f(x)=x^{2}$ , then the graph is shifted 2 units to the right.
