Answer:
See below
Step-by-step explanation:
The Fundamental Theorem of Algebra states that the degree of the polynomial is the number of roots, where some may be complex depending on the polynomial or degree.
In this case, 2x^2-x+2=0 has its highest degree of 2, so there are 2 roots.
N=1/5 I think i had this question before.
In an hour the distance will be 27+3=30 miles
27*x+3*x=41
30*x= 41
x= 41/30 hours
x= 1,3(6) hours
Answer:
f(4) = 85.
Step-by-step explanation:
When you substitute the 4 into the x and solve for f(4), all that means is that every x in the equation becomes 4. There's only one on the right side: the 18x. This becomes 18*4, or 72, which is then added to 13, to get 85.
