Answer:
the answer is d (x+4)^2/9 - (y-1)^2/25
Step-by-step explanation:
its correct on edge
I'm pretty sure the original price would be $90.75 because 3/4 is .75, so all you have to do is add that to the $90
Answer:
n = 3; enlargement
Step-by-step explanation:
The dashed-line figure is larger. That is the meaning of "enlargement."
Points on the dashed-line figure are 3 times the distance from point H as the corresponding point on the sold-line figure, so the scale factor is 3.
Answer:
Let b=x
Such that b^2 =8b-8 will x^2=8x-8
Using the almighty quadratic formula
x1={-b+sqrt (b^2-4ac)}/2a
x2={-b-sqrt (b^2-4ac)}/2a
From the question
a=1
b=8
c=-8
x1={-8+sqrt (8^2-4(-8))}/2
x1=(-8+5.66)/2
x1=-1.17
x2={-8-sqrt (8^2-4(-8))}/2
x2=(-8-5.66)/2
x2=-6.83
:.(x1,x2)=(-1.17,-6.83)
Step-by-step explanation:
Let the land area of country A = a
and the land area of country B = b
a + b = 199973
a = b + 573
(b + 573) + b = 199973
2b = 199400
b = 99700
a = 100273
The land area of country A is 100,273 square kilometers
and the land area of country B is 99,700 square kilometers.
