For example smallest x which makes inequelity is x =14
because 14 + 7 = 21 > 20
you can take any number >= 14
Answer:
$12.40
Step-by-step explanation:
You can set this up as .20 x 62 which will give you $12.4 or $12.40. You get .20 by converting 20% to a decimal. Also you can simply put 60-20% on a calculator.
Step-by-step explanation:
for a mid point of (-3,-5) and(5,3) is.
(X1,Y1)= (-3,-5)
(X2,Y2)=(5,3)
now,
midpoint=(x1+x2)/2, ,(y1+y2)/2
=(-3+5)/2, (-5+3)/2
=2/2, (-2)/2
=( 1, -1)
:- midpoint=(1,-1)
Answer:
4x / (2x^2+1)
Step-by-step explanation:
g(x)=ln(2x^2+1)
Using u substitution
u= 2x^2 +1
du = 4x dx
g'(x) = d/du ( g(u) du)
We know that the derivative of ln(u) = 1/u since this is always positive
= 1/ u* du
Substituting x back into the equation
g'(x) = 1/(2x^2+1) * 4x
= 4x / (2x^2+1)
