Answer:
centre= (2,-3)
radius=2
equation= (x-2)^2+(y+3)^2= 4
Step-by-step explanation:
equation is found by the co-ordinates and the length of the radius
if the co-ordinates (2,-3)
x=2
y=-3
r= 2
so the equation will be like
=(x-2)^2+(y+3)^2=2^2
=(x-2)^2+(y+3)^2=4
Thankyou ^^
Answer:
$13.99
Step-by-step explanation:
20% of $69.99 is $13.998
We get this by taking 69.99 X .2 = 13.998
Technically she would save $14 if we rounded up. But most stores will round down in order to save more money.
I will have to assume that you actually meant " e^(ln 7x). The exponential and logarithmic functions are inverses of each other, so d^(ln 7x) = 7x (answer C).
Subtract 5x from both sides, 7x+2=-26, subtract 2 from both sides, 7x=-28, divide both sides by 7, x=-4
