Answer:
the answer to this question is x=21
Step-by-step explanation:
Hope this didnt help
x^2b + t = x^2e
x^2e - x^2b = t
x^2(e - b) = t
x^2 = t /(e -b)
x = √[t /(e -b)] or x = - √[t /(e -b)]
The answer is B, 5*2*30. Hope this helps
The piecewise-defined function with linear parts f(x)= |2x + 9|
f(x) = {2x + 9 x ≥ -9/2)
{-2x - 9 x < 9/2}
<h3>How to write piecewise functions?</h3>
To write this function as a piecewise function, you have to use the definition of absolute value.
The absolute value equation is; f(x)= |2x + 9|
The definition says that;
|x| = {x x ≥ 0)
{-x x < 0}
Applying this definition to the function you get:
|2x + 9| = {2x + 9 2x + 9 ≥ 0)
{-2x - 9 2x + 9 < 0}
After simplifying the inequalities you get:
|2x + 9| = {2x + 9 x ≥ -9/2)
{-2x - 9 x < 9/2}
So finally you can write the piecewise function as:
f(x) = {2x + 9 x ≥ -9/2)
{-2x - 9 x < 9/2}
