Answer:
2
Step-by-step explanation:
first, add terms
8 + 5 + 12 + 4 + 5 + 8 + 7 = 49
seven terms, therefore we divide by 7
49/7 = 7
find distance
8-7= 1
7-5= 2
12-7=5
7-4=3
7-5=2
8-7=1
7-7=0
added together you get 14,
14/7 = 2
your answer is 2
hope this helps:)

Answer:
x = 5/2 and 3.
Step-by-step explanation:
Factor the equation. Find numbers that will sum up to -11 involving the coefficient of 2, and that multiply into 15.
2x² - 11x + 15 = 0
(2x - 5)(x - 3) = 0
Use the Zero Product Property to solve for the roots of this equation:
2x - 5 = 0
2x = 5
x = 5/2
----------
x - 3 = 0
x = 3.
Therefore, the two values of x that are roots of this equation are:
x = 5/2 and 3.

Answer:
Step-by-step explanation:
so to find the equation tangent to the curve x^2+1 at the point (1,2)
-First we must find the derivative then plug in the point
d/d(x)=2x (power rule)
so then we plug in the x and y values (we don't need to worry about the 2-y value- because we did not need to compute and derivatives with y)
so we plug in 1 for the x
y=2(1)
2
now we plug it into equation of a line
y - 2 = 2(x - 1)
or
y=2x
