Answer:

The next number to complete the sequence is 13

Step-by-step explanation:

The sequence of given data is the reducing number by the specific value and the add double of same number in the outcome.

The difference between numbers

-6-3 = -9

12 -(-6) = 18

4 - 12 = -8

20 - 4 = 16

The pattern if behaves as

x-n

x-2x

According to given pattern new number should be

x - 20 = -7

x = -7 +20

x = 13

The next umber will be 13

Answer:

13

Step-by-step explanation:

From the sequence above the number has a negative sign,increasing and decreasing at rates not quite understandable unless a proper attention is paid.

The sequence of the above data is the reducing number by the specific value and the add double of same number in the outcome.

Take a look a this

-6-3 = -9(the first number is subtracted from the second)

12-(-6)=18

4 - 12 = -8

20 - 4 = 16

From the above one can realize that the outcome of every single linear algebra having the -ve sign will increase by 1(that means +1 is added to the previous number with a negative sign.

So to following the sequence, the next number will b -7

According to given pattern new number should be

x - 20 = -7

x = -7 +20

x = 13

Cameron said that the Y intercept of a quadratic function always tells the maximum value of the function. explain Cameron's erro
Leno4ka [110]

Answer:

We can have two cases.

A quadratic function where the leading coefficient is larger than zero, in this case the arms of the graph will open up, and it will continue forever, so the maximum in this case is infinite.

A quadratic function where the leading coefficient is negative. In this case the arms of the graph will open down, then the maximum of the quadratic function coincides with the vertex of the function.

Where for a generic function:

y(x) = a*x^2 + b*x + c

The vertex is at:

x = -a/2b

and the maximum value is:

y(-a/2b)

It's linear

If you evaluate x when it's 0 you'll get the cut in y, that means the function will pass on (0,7)

The formula for linear functions is y=mx +b

In this case b is 7

M=7-5/0+1

M=2

Now you just write the function down, it would be

F(x) =2x + 7

The question is asking you which shape is the same shape as the shape displayed with the question. The shape could be bigger, smaller, flipped around, or any other different way, but it has to be the same shape.

The answer is B.

The reason why B is your answer because the shape is the same, but it's just that it is smaller. The shapes scale is just smaller, but it's still the same shape. and flipped around.
