What’s the next three numbers after 1, -3.9,27

Mathematics
1 answer:
4vir4ik [10]3 years ago
4 0

Answer:

-105.3,729,-2843.1

Step-by-step explanation:

so I ruled out addition and subtraction cause it's not decreasing or increasing regularly

so I considered division and multiplication

where I did the latter over the former

3.9/1= -39/10 and 27/-3.9=-90/13

so I used the two to form an alternating pattern

27×{-39/10}= -105.3

-105.3×{-90/13}= 729

729×{-39/10}= -2843.1

Domain and range of graph need ASAP
Lostsunrise [7]

Answer:

Domain: -6 \leq x \leq 3

Range: -3 \leq x \leq 6

Step-by-step explanation:

The domain is the set of real values which can be inputted into a function and produce a real output. In this case, the domain is the following: -6 \leq x \leq 3, because this is the set of real values for which the function will produce a real output.

The range is the set of real values which a function outputs when a value from the domain is entered into the function. This is the set of y-values that one can see on the graph, the possible y-values are in between (-3) and (6).

Find the equation of a line that is parallel to the line x equals negative 1x=−1 and contains the point left parenthesis negativ
sineoko [7]
The equation of the line is given as y-x=-1

A straight line equation is given in the form y=mx+c where m is the gradient and c is the y-interest.

We need to rearrange y-x=-1 to make y the subject. 
y= x-1 ⇒ from here we can read the gradient and the y-intercept. The gradient, m=1 and c=-1.

<span>A line that is parallel to y=x-1 will have the same gradient, m=1 but different y-intercept. One example of equation of a line that is parallel to y=x-1 is y=x+3
