Add 3 to both sides so that the equation becomes -2x^2 + 5x + 5 = 0.
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -5 ± √(5^2 - 4(-2)(5)) ] / ( 2(-2) )
x = [-5 ± √(25 - (-40) ) ] / ( -4 )
x = [-5 ± √(65) ] / ( -4)
x = [-5 ± sqrt(65) ] / ( -4 )
x = 5/4 ± -sqrt(65)/4
The answers are 5/4 + sqrt(65)/4 and 5/4 - sqrt(65)/4..
X= # tickets Shaun sold
1/2x+3= # tickets Trudy sold
Add them together.
= x + (1/2x + 3)
combine like terms
= (x + 1/2x) + 3
= 1 1/2x + 3
convert to improper fraction
= 3/2x + 3
ANSWER: 3/2x + 3 (3rd choice down)
Hope this helps! :)

Answer: <em>f(x) </em>is a polynomial. The degree is 5 and the leading coeficient is -7.
Step-by-step explanation:
1. By definition a polynomial is the sum of terms that consist of a number (which is called "coefficient") that multiplies a variable with an exponent (This exponent is a whole number). Therefore, the function is a polynomial.
2. To find the degree of the polynomial you must see the greatest exponent. In this case, this is 5. Therefore, the degree is 5.
3. The leading coefficient is the number that multiplied the variable with the greatest exponent. Therefore, the leading coefficient is -7.
