Answer:
Step-by-step explanation:
Rewrite equation: 
Factor out 
:
Divide both sides by 
:
Anything to the power of 1 is itself. Hence,
Hello :
the center of this cercle is : O( 0, 0)
calculate the slope m of the line : OA .. A (3,-4)
m= (yA - yO) / (xA- xO)
m = (-4-0)/(3-0)
m= -4/3
if : k the slope of the tangent : k×m = -1 (the tangent perpendiclar of : OA)
k× (-4/3) = -1
k = 3/4
an equation of this tangent is : y - (-4) = (3/4)(x-3)
Answer: 57.14%
Step-by-step explanation:
Because it’s not 4.76% or 10%, and 210% seems drastic. Lemme know if it’s right though.
Answer:
5+3a=29
Step-by-step explanation:
let Ella's age be 'a'
Vicki's age=5+2a
sum of their ages= 29
So, the equation is
(5+2a)+a=29
5+3a=29
<em>hope this helps!</em>
the answer is b, just divide 50 by 59 and multiply that sum to 6.4
