Answer:
.
Step-by-step explanation:
From the given table it is clear that x and y are linearly related.
Now, any two points that satisfy the relation between x and y are sufficient to express the equation.
The first two given points are (2,3), and (4,4).
Therefore, the equation is

⇒ . (Answer)
Answer:
5x3+5x2-55x-15
Step-by-step explanation:
The number of people who grow potatoes is 3 times the number that grow sugar beet.
⇒ 48 + x = 3( x + 12)
--------------------------------------------
Solve for x :
--------------------------------------------
48 + x = 3( x + 12)
48 + x = 3x + 36
2x = 12
x = 6
--------------------------------------------
People who do both grow either.
--------------------------------------------
Number of people who does not grow potato or sugar beets = 100 - 48 - 12 - 6 = 34
------------------------------------------------------------------------------
Answer: The answers are 6 and 34.
------------------------------------------------------------------------------
"6" is inbetween "48" and "12".
"34" is outside the two circles.
let 'x' represent the number of all the passes for the year
350 passes = 70% of all the passes
350 passes = 70% of x
0.70x = 350
by solving we find:
x = 500 passes
The coordinates of the midpoint of AB is (4.5, -1.5)
We can find this by taking the average of each coordinate. The average of the x's (2 and 7) is 4.5, while the average of the y's (-4 and 1) is -1.5.
The coordinates of the midpoint of CD is (-5.5, 1)
We can find this by taking the average of the coordinates as we did in the first one. The average of the x's (-3 and -8) is -5.5, while the average of the y's (-2 and 4) is 1.
