Answer:
2. increasing when x > 0
the result of root is a positive number
and since there is no value of neg number in roots so it's increasing when x>0
plus in zero it self has a positive number (0,8)
but u cannot find either it's increasing or decreasing in zero bcoz in first derivative test
when x =0
y= not defined
The answer would be D. because the point-slope formula is y-y1=m(x-x1). Since both of the numbers in the point are positive the equation will be the same. You will just substitute the numbers into the equation making it answer D.
Percent is parts out of 100 so
45%=45/100=9/20
'of' means multiply
18 =9/20 times something
multiply both sides by 20/9 to clear fraction
360/9=something
40=something
the value is 40
