Answer:
x = -24
Step-by-step explanation: Please brainliest!
Subtract 1/3 from both sides of the equation.
x/12 + 1/3 = 5/3
x/12 + 1/3 - 1/3 = -5/3 - 1/3
-----------------------------------------------------------
Simplify and subtract the numbers.
x/12 = 2
-----------------------------------------------------------
Multiply all terms by the same value to eliminate fraction denominators.
x/12 = -2
12 . x/12 = 12 (-2)
------------------------------------------------------------
Cancel multiplied terms that are in the denominator.
12 . x/12 = 12 (-2)
x = 12 (-2)
------------------------------------------------------------
Multiply the numbers.
x = 12 (-2)
x = -24
Answer x = -24
The 2-point form of the equation of a line is
.. y = (y2 -y1)/(x2 -x1)*(x -x1) +y1
For your points (x1, y1) = (0, 3) and (x2, y2) = (3, 5), this is
.. y = (5 -3)/(3 -0)*(x -0) +3
.. y = (2/3)x +3
Written as a function, it is
.. f(x) = (2/3)x +3
1,2,2,2,3,3,3,3,4,4,4,4,5 are all the test scores. if you add them all up, its 40, and there are 13 numbers in the data set, so you divide 40 by 13, and you get 3.07692 overscore, or 3 and 10/13
