Answer:
Step-by-step explanation:
The given expression is
We have to find the value of given expression when -x=-4/5 and y= 1/3.
Substitute -x=-4/5 and y= 1/3 in the above expression, to find the value of given expression when -x=-4/5 and y= 1/3.
After multiplication we get
Taking LCM, we get
Therefore, the value of given expression is .
A)
Increase %= (new # - old #)/old * 100
new= 8
old= 5
Increase %= (8-5)/5 * 100
=3/5 * 100
=0.60 * 100
=60% increase
B)
Decrease %= (old # - new #)/old * 100
new= 5
old= 8
Decrease %= (8-5)/8 * 100
= 3/8 * 100
= 0.375 * 100
= 37.5% decrease
ANSWER: a) 60% increase; b) 37.5% decrease
Hope this helps! :) Good luck on your test!!
Answer:
(x-10)^2 + (y-2)^2 = 49
Step-by-step explanation:
I'm assuming that 10-2 means (10,2)
Equation of circle:
(x-a)^2 + (y-b)^2 = r^2
Plugging in the values that we know:
(x-10)^2 + (y-2)^2 = 7^2
(x-10)^2 + (y-2)^2 = 49
Hope this helps!
-2 would be the coefficient of the y-term
