We calculate the sum of all interior angles using this formula 180(n-2) , n=number of sides
180(40-2)= 6840
6840 ÷ 40 = 171
Mean of the 5 is the average
lets solve for what score gets 80
and lets say last score is x
so
(sum of scores)/4=80
(62+75+90+x)/4=80
(227+x)/4=80
times 4 both sides
227+x=320
minus 227 from both sides
x=93
yo need a 93
good luck
Answer:
1) 5/1 is the slope, and 10 is the y intercept.
2) Inital amount is the y intercept, and 10 is the rate of change.
3) Should be easy from there! Just graph (0,10), and go up 5, right 1, and repeat.
Step-by-step explanation:
This is in slope intercept form! Where 5 is the slope, and 10 is the y intercept. The rate of change is another way of saying slope, and the inital amount is your starting value, or y intercept.

Answer:
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept → (0, </em><em>b</em><em>)</em>
<em />
The fromual of a slope:
<em>(x₁, y₁), (x₂, y₂)</em><em> - points on a line</em>
<em />
We have the points from the graph:
(0, 1) → <em>b = 1</em> and (3, 3).
Calculate the slope:
Finally we have the equation of a line:
