Answer:
C. (1,-2)
Step-by-step explanation:
The solution to a system of equations is where the graphs intersect.
The graphs intersect where x = -1 and y = -2
Answer:
Part 1)
The possible multiplicities are:
multiplicity 1
multiplicity 3
multiplicity 1
multiplicity 2
Part 2
The factored form is

Step-by-step explanation:
Part 1.
The missing diagram is shown in the attachment.
The zeroes of the seventh degree polynomial are the x-intercepts of the graph.
From the graph, we have x-intercepts at:
,
,
, and
.
The multiplicities tell us how many times a root repeats.
Also, even multiplicities will not cross their x-intercept, while odd multiplicities cross their x-intercepts.
The possible multiplicities are:
multiplicity 1
multiplicity 3
multiplicity 1
multiplicity 2
Note that the total multiplicity must equate the degree.
Part 2)
According to the factor theorem, if
is a zero of p(x), then
is a factor.
Using the multiplicities , we can write the factors as:




Therefore the completely factored form of this seventh degree polynomial is 
Answer: 7.1 inches
Step-by-step explanation:
The area of a square is simply the square of one of its length. Therefore since we are informed that the area of the square box is given as 50 inches².
Then the best estimate of the length of one side will be the square root of 50 which will be:
= ✓50
= 7.1 inches approximately
