Lets say you have a spinner with 6 sides. Numbers 1-6

The probability of each number to be landed on is 1/6 or about 16%

For an even number to be landed on, it would be 3/6 or 1/2 or 50% bc there are 3 even numbers: 2,4, and 6

What are the solutions to the equation 2x^2 + 9x =5

Maksim231197 [3]

Answer:

$\displaystyle -5 \ and \ \frac{1}{2}$

Step-by-step explanation:

$2x^2 + 9x =5$

we have to move 5 in the other side with a different sign, to get a 2 grade ecuation

$2x^2 + 9x -5= 0$

now we know

a=2

b=9

c=-5

we have to find delta

$\boxed{\Delta=b^2-4ac} \\\\ \Delta=9^2-4\cdot2\cdot(-5)\\ \Delta=81+40 \\ \Delta=121$

and now we have to use the formula to find the root square

$\displaystyle \boxed{ X_{1,2}=\frac{-b\pm\sqrt{\Delta} }{2a} }$

$\displaystyle X_1=\frac{-b-\sqrt{\Delta} }{2a} =\frac{-9-11}{2\cdot2}=\frac{-20}{4} =-5$

$\displaystyle X_2=\frac{-b+\sqrt{\Delta} }{2a} =\frac{-9+\sqrt{121} }{2\cdot4} =\frac{-9+11}{4} =\frac{2}{4} =\frac{1}{2}$
