He got 42,000 subs in the 2 weeks.
Step-by-step explanation:
radius = 7
the equation of a circle in standard form is
(x-a)² + (y-b)² = r²
where (a, b) are the coordinates of the centre and r is the radius
To obtain this form ' complete the square ' on both the x and y terms
x² + 2(1)x + 1 + y² + 2(3)y + 9 = 39 + 1 + 9
(x+1)² + (y+3)² = 49 ← in standard form
with centre (1, 3) and r = √49 = 7
Answer:
yes
Step-by-step explanation:
Answer:
(25x * 4y * 2z) + (15x * 2y^3)
10xy(20z + 3y^2)
(if you want working, just comment [too much effort lol])
To eliminate x, you can multiply the second equation by 2. This will make -2x into -4x, so that 4x and 4x will be able to cancel out leaving you to solve for y.
To eliminate y, you can multiply the second equation by 3. This will make 3y into 9y, so that -9y and 9y will be able to cancel out leaving you to solve for x.
Hope this helped.
