Kobotan [32]
9 x² + 16 y² = 144  /:144
\frac{ x^{2} }{16} + \frac{ y^{2} }{9} =1
General formula of ellipse ( the center is at the origin ):\frac{ x^{2} }{ a^{2} }+ \frac{ y^{2} }{ b^{2} } =1 
a² = 16,  b² = 9
Domain: [-a, a ] = [-4, 4]
Range:[-b, b ]
Answer: B ) ellipse.
Domain: { -4 ≤ x ≤ 4 }
Range: { -3 ≤ y ≤ 3 }

Which statement best explains the value of 17 - (-3)?
djverab [1.8K]

B) the additive inverse of -3 is +3, so 17-(-3) = 20 is your answer.

Remember, two negatives = one positive, and so:

- (-3) = 3

17 + 3 = 20

Therefore, B is your answer

hope this helps

Solve the following system. y = x 2 - 9x + 10 and x + y + 5 = 0. The solutions are
shepuryov [24]
X+y+5=0

y=-x-5

If a solution exists y=y so we can say

x^2-9x+10=-x-5  add x+5 to both sides

x^2-8x+15=0 now factor

x^2-3x-5x+15=0

x(x-3)-5(x-3)

(x-5)(x-3) so x=3 and 5, using y=-x-5

y(3)=-8 and y(5)=-10

So the two solutions are:

(3,-8) and (5,-10)
