Answer:
negative 9 plus or minus the square root of 17 divided by 8
Step-by-step explanation:
move all terms to one side
4x^2 + 9x + 4= 0
Use the quadratic formula
and you get negative 9 plus or minus the square root of 17 divided by 8
3 sin x + 5 cos x = 0
3 sin x = - 5 cos x /: cos x ( divide both sides by cos x )
3 sin x / cos x = - 5
3 tan x = - 5
tan x = -5/3
x = arc tan (-5/3)
x ≈ - 59.036°
5 * 20 +7= 67..................
Answer:



Step-by-step explanation:
We can create an equation for this problem by converting the words to an equation.
The <em>flat fee</em> was $119. We then add $75 for every hour worked. This means that this becomes
. Since the total cost was $306.50, the equation is
.
We can now solve for x, the amount of hours worked, to find it’s value.

Hope this helped!
