Answer:
(2x-1)(x+3)
Step-by-step explanation:
2x^2+5x-3
2x^2-x+6x-3
x(2x^2/x - x/x) +3(2*3x/3 - 3/3)
(2x-1)(x+3)
First find equation
center is (h,k) then
(x-h)^2+(y-k)^2=r^2
given
(7,0) is center
(x-7)^2+y^2=r^2
also given (2,0)
(2-7)^2+0^2=r^2
(-5)^2=r^2
25=r^2
(x-7)^2+y^2=25 is equation
take derivitive of both sides, implicit differntiaton
2(x-7)+2y dy/dx=0
2(x-7)=-2y dy/dx
(7-x)/y=dy/dx
at (2,0)
(7-2)/0
undefined
that means the line is x=something
(2,0)
the equation is x=2
The answer would be an=-2+5n
Answer:
19: The difference between the temperature in Fair Banks and Barlow is 3°F
20: -13°F, -10°F, 15°F, 24°F.
Step-by-step explanation:
I'm assuming that by "compare", it means to find the difference between temperatures in question 19. If it means something else, let me know and I'll try and help you find it.
