4/3 or 1.3. hope this helps.
3+p=8
-p -p
3=8-p
-8 -8
-5=-p
swap signs
5=p
In mathematical notation, ∑ means summation. So wherever you see the symbol, you have to sum over all elements in the set. Let's solve the question.
a. ∑m means, to sum all elements in the set m: ∑m = 12 + 15 + 20 + 30 = 77
b. ∑ means to sum all elements in the set f as the square of the elements f =
c. ∑mf means to sum all elements as the product of the elements of m and f = (12×5) + (15×9) + (2010) + (30×16) = 875
d. ∑ means to sum all elements as the product of the square of m and f =
Multiply -8 on both sides
n + 2 = 32 Subtract 2 on both sides
n + 2 - 2 = 32 - 2
n = 30
The y-intercept is 2 and the Slope is 2/4 but if you simplify that, it will be 1/2.
