Answer:
-0.38268343236 (or 0.382)
Ok, so what happend was 4 was added to every x, the whole thing was multiplied by -1 and -2 was added to the whole function
so
adding 4 to every x shifts the graph to the left 4 units
multiplying the whole function by -1 reflects it over the x axis
adding -2 to the whole function moves it down2 units
so that would be the first option
The <em>correct answers</em> are:
A) Both can be solved by graphing;
C) Both can be solved by substitution; and
D) Both have solutions at the points of intersection.
Explanation:
Just as a system of linear equations can be solved by graphing, a system of quadratic equations can as well. We graph both equations. We then look for the intersection points of the graphs; these intersection points will be the solutions to the system.
We can also solve the system by substitution. If we can get one variable isolated, we can substitute this into the other equation to solve.
Answer:
r is the common ratio (in geometric sequence)
d is the common difference (in arithmetic sequence)
n is the term number
a1 is the value of the first term
an is the value of the nth term
Step-by-step explanation:
arithmetic sequence formula:
an=a1+d(n-1)
geometric sequence formula:
an=a1•(r)^(n-1)
