Answer:
y = 3x -18 ( where y = balls sent back by Rudolf; x= balls given to Rudolf)
Step-by-step explanation:
x (Balls given) y( Balls sent back)
8 6 Δy/Δx = (27-6)/(15-8) = 3
15 27
25 57 Δy/Δx = (57-27)/(25-15) = 3
Observing the number sequence shows constant gradient and as such we can use equation of a straight line to relate the two variables.
Using the equation of a straight line we have:
(y-y1)/(x-x1) = (y2-y1)/(x2-x1)
y-6/x-8 = (27-6)/(15-8)
y-6/x-8 = 3
y-6 = 3(x-8)
y-6 = 3x - 24
y = 3x-18
12y = 132
Now, solve for y.
Do the inverse operation.
12y = 132
12y/12 = 132/12
y= 132/12
y= 11
Equation: 12y = 132
Y equals: 11
Answer:
69
Step-by-step explanation:
both edges equal 90 degrees
90 plus 90 plus 111 =291
360-291
-3(x+4)+6
-3x-12+6
-3x-6 <= that’s the answer but just in case you want to find what “x” is:
-3x-6=0
add 6 to both sides
-3x=6
divide -3 to both sides
x=-2
Answer:
Yes they can it would be a isosceles triangle.
Step-by-step explanation:
An isosceles triangle can have 1 side that is different from the other 2.
