Answer:
it is -30
Step-by-step explanation:
you would divide both sides by x,then f=2
using PEMDAS we come to -30

155 x (11/20) =85.25 feet
Answer:
d=.5
Step-by-step explanation:
Subtract 1/3 from 5/6 and you will get your answer which is .5
Answer:
2
Step-by-step explanation:
f(x)=2x^2+9x-5
When we are find how many times it intersects the x axis, we are finding the zero's. Set the equation equal to zero
0=2x^2+9x-5
Factor the equation
0 = (2x+1) (x-5)
2*1
1*-5 = -5
2*-5 +1*1 = -9
This checks for the first last and middle terms so we factored correctly
Then using the zero product property
2x+1 = 0 and x-5 =0
2x = -1 x=5
x = -1/2 and x=5
This function crosses the x axis 2 times
