There are multiple ways to calculate slope.
Firstly, if you have a graph, it is rise over run. (Also y2-y1/x2-x1) this calculates the difference between 2 points on both their x and y axis, so they are the same.
Also from equation form.
Y=mx+b (the m is the slope)
ax+by= (-a/b is the slope)
Answer:
see explanation
Step-by-step explanation:
Using the product/ difference identity
sinxsiny = 
[ cos(x - y) - cos(x + y) ]
Consider the left side
2sin(
+ α)sin( - α )
= cos[ + α - + α ] - cos [ + α + - α ]
= cos2α - cos
= cos2α - 0
= cos2α = right side , thus proven
J+(18/(-4))=8
j-9/2=8
2j-9=16
2j=25
j=25/2=12.5
--------------------------------------
TEST:
12.5+(18/(-4))=8 (Therefore the value of j is correct.)
Answer:
18 people.
Step-by-step explanation:
Are you going to lay a protractor on the pizza and measure 40° ?) Multiply that by two(because theres two pizzas) so 18 people.
