Equatin of a line in slope intercept form is y = mx + c; where m = (y2 - y1)/(x2 - x1) = (14 - 2)/(10 - 0) = 12/10 = 6/5
Equation of a line is obtained by (y - y1) = m(x - x1)
(y - 2) = 6/5(x - 0)
y - 2 = 6/5x
y = 6/5x + 2
Let us say that the number of weeks is "x" and the number of chores is "y".
If we state an algebraic expression for Janie's allowance it would be
3x+2y=13
However, there are two variables, hence many answers. To solve this problem, there must be more information about the relation between x and y.
Answer:
the correct answer is 24.9
Step-by-step explanation:
Answer:
x = 11, y = 17
Step-by-step explanation:
Set the equations equal to each other. Since the vertical angles are congruent, 8x + 7 = 9x - 4 and 5y = 7y - 34. Now, solve your equations for the x and y values.
8x + 7 = 9x - 4
x = 11
5y = 7y - 34
2y = 34
y = 17
