The answer would be D.

The answer is D because the dot is on -2 and the direction of the arrow is based on the inequality symbol. In this case, since the sign is 'greater than', the arrow would also be facing the same direction as the sign. Also, the dot is always open whenever there is just a 'greater than' sign.

The dot would be closed if it were a 'greater than or equal to sign'.

2. The equation of a circle is x^2 + 2x + y^2 + 6y = 0.

pentagon [3]

Answer:

a)
${x}^{2} + 2x + {y}^{2} + 6y = 0$
${x}^{2} + 2x + 1 + {y}^{2} + 6y + 9 = 10$
${(x + 1)}^{2} + {(y + 3)}^{2} = 10$
b)
center I(-1;-3)

Please help me, I don't know how to solve it

goblinko [34]

Answer:

2a-3 and a+4

Step-by-step explanation:

Given the equation

2a²+8a -15 = 3a - 3

We are to find one of its factors

Equate the expression to zero

2a²+8a -15 = 3a - 3

2a²+8a -15 - 3a + 3 = 0

Collect the like terms

2a²+8a - 3a - 15 + 3= 0

2a²+5a - 12= 0

Factorize

2a²+8a-3a - 12= 0

2a(a+4)-3(a+4) = 0

(2a-3)(a+4) = 0

Hence the factors are 2a-3 and a+4

Let f(x) =x+5 and g(x)=x^2-3 then f(g(x)) =?

guajiro [1.7K]

Answer:

Option (a) is true.

Step-by-step explanation:

Given the function

$f(x)=x+5$

$g\left(x\right)=x^2-3$

(f∘g)(x) = f(g(x)) = f(x²-3) = (x²-3)+5

= x² + 2

Thus,

f(g(x)) = x² + 2

Therefore, option (a) is true.
