The residual value when x = 4 is 6.72 if the line of best fit to be y = 2.78x – 4.4
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more number and variables.
Given the function:
y = 2.78x - 4.4
When x = 4:
y = 2.78(4) - 4.4 = 6.72
The residual value when x = 4 is 6.72 if the line of best fit to be y = 2.78x – 4.4

1. -9 need to multiple to both number
-9 X n= -9n -9 X -3 = 21
-9n + 21
2. -10 X 9n = -90n -10 X 3 = -30
-90n - 30 - 8
-90n - 38
Hope that helps

Answer:
3) 146 degrees
4) 471 degrees
5) x = 100 and 3x = 300
Step-by-step explanation:
all three are polygons whose sum of all interior angles can be found by using the formula (n - 2)*180 where 'n' refers to the number of sides
In #3 and 5 there are 5 sides, so (5 - 2)*180 = 3(180) giving a total of 540 degrees. Add all known angles and deduct from 540.
#4 has 7 sides, so (7 - 2)*180 = 1260 degrees. Add all known angles and deduct sum from 1260.
#5 Add all integers plus 'x' + '2x' to get 240 + 3x = 540
