A geometric sequence follows a pattern with a common ratio.

Find the ratio between 3 and 9

If you multiply 3 by 3 the answer would be 9.

The common ratio is 3.

Now multiply 9 by 3 to get 27.

The answer is D. 27

The first step in determining the solution to the system of equations, y = -x2 - 4x - 3 and y = 2x + 5, algebraically is to set

sweet-ann [11.9K]

Answer:

Combine like terms onto one side of the equation

Step-by-step explanation:

You have

-x^2 -4x - 3 = 2x + 5

It seems that we should combine like terms to make this equations smaller.

-x^2 - 4x - 3 - 2x - 5 = 0

-x^2 -6x - 8 = 0

- (x + 2)(x + 4) = 0

x = -2 or x = -4

Can someone plz help I do not know what I am doing

PolarNik [594]

the answer is D-n is greater then or equal to nine.

because the red dot starts on nine and goes up its greater than nine and because its on nine its also going to equal it. I had a problem getting the signs messed up when I learned it but I remember the sign always eats the greater number. I hope this answer could help and I'm sorry if the answer is incorrect.

Determine which consecutive integers do not have real zeros between them.

Alisiya [41]

The answer is option c (-1,0)
Solving the equation you get that the zeros of this are approximately
x ≈ -2.8019
x ≈ -1.4450
x ≈ 0.24698
Then the function has three real roots, but none of them is within the range (-1,0)
Below is a graph of the function.
